[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] <Overall system configuration> 1 is a schematic diagram showing a cranial shape correction helmet management system 1 according to one embodiment of the present invention. The cranial shape correction helmet management system 1 is a system for manufacturing a cranial shape correction helmet 7 that corrects the shape of the head of a subject 100. As shown in FIG. 1, the cranial shape correction helmet management system 1 of this embodiment includes a doctor's terminal 2, a server 3, a manufacturing terminal 4, and a subject's terminal 5.

[0012] The doctor terminal 2 is an information processing device used by a therapist who treats the subject 100. The therapist is, for example, a doctor or a doctor's assistant. The doctor terminal 2 is, for example, configured by a personal computer, a smartphone, a tablet, or the like.

[0013] The therapist acquires shape data on the shape of the head of the subject 100 in order to measure the shape of the head of the subject 100. For example, the therapist performs 3D scanning to capture the head of the subject 100 at various angles and acquires shape data. Examples of the shape data include a plurality of images, videos, 3D data, etc. captured of the head of the subject 100. In this embodiment, in order to improve the measurement accuracy of the head shape, the subject 100 is photographed while wearing a cap 6 having an identification marker. Note that the cap 6 is not necessarily required for measuring the head shape of the subject 100 in the 3D scanning. The captured shape data (3D scan data) is uploaded from the doctor's terminal 2 to the server 3.

[0014] The server 3 is connected to the doctor's terminal 2, the manufacturer's terminal 4, and the patient's terminal 5 via a predetermined communication network such as the Internet. The server 3 is an information processing device that receives (input processing) and provides (output processing) various information for manufacturing the cranial shape correcting helmet 7 to the doctor's terminal 2, the manufacturer's terminal 4, and the patient's terminal 5. The server 3 is, for example, configured by a computer.

[0015] The manufacturing terminal 4 is an information processing device used by a manufacturer who manufactures the cranial shape correction helmet 7. The manufacturing terminal 4 is configured, for example, by a personal computer, a smartphone, a tablet, etc. The manufacturer downloads multiple images, videos, or 3D data of the head of the subject 100 from the server 3 through the manufacturing terminal 4, and generates 3D data showing the shape of the head of the subject 100 and manufactures the cranial shape correction helmet 7 based on the data.

[0016] The subject terminal 5 is an information processing device used by the subject 100 or a person related to the subject 100. For example, a person related to the subject 100 is a guardian when the subject 100 is an infant. The subject terminal 5 is configured by, for example, a smartphone, a tablet, a personal computer, or the like.

[0017] The skull shape correcting helmet 7 is worn on the head of the subject 100 to promote deformation so that the skull shape is corrected as the skull grows. The subject 100 may be, for example, an infant or a small child with a skull deformity requiring treatment, such as plagiocephaly, brachycephaly, or dolichocephaly. Plagiocephaly is a deformed shape in which the skull is not symmetrical but is tilted to one side. Brachycephaly is a deformed shape in which the skull is significantly short in the anterior-posterior dimension. Dolichocephaly is a deformed shape in which the skull is significantly long in the anterior-posterior dimension. Note that the subject 100 is not limited to an infant or a small child.

[0018] Next, an example of the configuration of the cranial shape correcting helmet 7 that is managed by the cranial shape correcting helmet management system 1 will be described with reference to Figures 2 and 3. Figure 2 is a perspective view showing an example of the cranial shape correcting helmet 7 managed by the cranial shape correcting helmet management system 1 according to an embodiment of the present invention. Figure 3 is a schematic cross-sectional view showing the shape of the shell 70 of the cranial shape correcting helmet 7. Figure 3 shows a horizontal cross section of the shell 70 as viewed in the up-down direction.

[0019] As shown in FIG. 2, the cranial shape corrective helmet 7 comprises an annular shell 70, a cushioned inner liner 71 that is disposed inside the shell 70 and contacts the head of the subject 100, and a belt portion 72 for adjusting the shape of the shell 70.

[0020] As shown in FIG. 3, the shell 70 has a cross-sectional shape formed in a substantially C-shape in a plan view, and forms a head accommodation space Sp inside. The shell 11 also has a gap with a slit width d between one end 73 and the other end 74. The shell 70 can accommodate changes in the head shape of the subject 100 by adjusting the size of the gap with the slit width d. When the head of the subject 100 grows larger, the belt part 72 can be adjusted so that the slit width d becomes larger, thereby making it possible to match the outer shape of the shell 70 to the head of the subject 100 that has grown larger. In this way, the cranial shape correction helmet 7 can adjust the size of the head accommodation space Sp that accommodates the head according to the treatment status of the head of the subject 100.

[0021] Note that the shape of the cranial shape correction helmet 7 described with reference to Figures 2 and 3 is just one example, and the items managed by the cranial shape correction helmet management system 1 can include cranial shape correction helmets 7 of various shapes and configurations.

[0022] <Hardware configuration> Next, an example of a hardware configuration for implementing the cranial shape corrective helmet management system 1 will be described.

[0023] First, an example of the hardware configuration of the doctor's terminal 2 will be described with reference to Fig. 4.

Alternatively, the processor 261 is a combination of a plurality of these. The processor 261 may also be a combination of these with a hardware accelerator or the like. The processor 261 controls each unit to realize various functions of the doctor's terminal 2 based on programs such as firmware, system software, and application software stored in the ROM 262, the RAM 263, or an auxiliary storage device that is a part of the storage unit 22. Note that a part or all of the programs may be incorporated in the circuit of the processor 261.

[0026] The photographing unit 21 is a device that photographs a subject, and mainly includes an imaging lens 211, an adjustment mechanism 212, an image sensor 213, and an A / D conversion unit 214.

[0027] The imaging lens 211 is composed of a lens that collects light in order to capture an image of a subject. Examples of the imaging lens 211 include a lens that forms an image of a subject on the light receiving surface of the image sensor 213 and a lens that can freely change the focal length within a certain range.

[0028] The adjustment mechanism 212 is a mechanism for adjusting the exposure time, aperture, ISO sensitivity, focal length, and the like.

[0029] The image sensor 213 forms an image of a subject on a light receiving surface where pixels are arranged two-dimensionally in a matrix, and converts the image into an electrical signal. The image sensor 213 may be, for example, a CMOS image sensor or a CCD image sensor.

[0030] The A / D conversion unit 214 converts the electrical signal read out from the image sensor 213 into a digital signal. An image is formed by the digital signal converted by the A / D conversion unit 214. The image captured by the imaging unit 21 is transmitted to the computer 26, the storage unit 22, the display unit 25, etc.

[0031] The storage unit 22 is a storage area for various programs and various data for causing the hardware group to function as the doctor's terminal 2, and can be configured with a ROM, a RAM, a flash memory, a solid-state drive (SSD), a hard disk drive (HDD), etc. Specifically, the storage unit 22 stores a program for causing the computer 26 to execute each function of this embodiment, the size of the image sensor 213 of the photographing unit 21, the size and shape of the identification marker of the cap 6, quality standards for images (described later), etc.

[0032] The communication unit 23 executes a process for the doctor terminal 2 to communicate with the server 3 and other devices. The communication unit 23 of this embodiment is configured to be capable of wireless communication between the doctor terminal 2 and the server 3.

[0033] The input unit 24 is a user interface that is electrically connected to the computer 26. The input unit 24 is composed of buttons and a display. The display is composed of, for example, a liquid crystal display (LCD) or an organic EL (Electro-Luminescent) display, and a touch panel that detects the position touched by the user is provided on the image display surface of the display. The user can input information by touching the image display surface of the display.

[0034] The display unit 25 is a user interface electrically connected to the computer 26. The display unit 25 is configured with a display. The display unit 25 displays images and various information transmitted from the photographing unit 21, the storage unit 22, the computer 26, etc.

[0035] In the doctor's terminal 2, the imaging unit 21 may be physically housed in the same housing as the other components, or may be a separate component independent of the housing that houses the other components. In the case of a separate component, the imaging unit 21 may be configured to exchange acquired image information with the other components through wired or wireless communication.

[0036] Next, an example of the hardware configuration of the server 3 will be described with reference to Fig. 5. Fig. 5 is a block diagram showing the hardware configuration of the server 3 in the cranial shape corrective helmet management system 1 according to an embodiment of the present invention.

[0037] 5, the server 3 includes a computer 33, a storage unit 31, and a communication unit 32. A bus 334 and the like connect these units together.

[0038] The computer 33 includes a processor 331, and a read-only memory (ROM) 332 and a random-access memory (RAM) 333 as main storage devices. The processor 331 is a central processing unit (CPU), a micro processing unit (MPU), a system on a chip (SoC), a digital signal processor (DSP), a graphics processing unit (GPU), an application specific integrated circuit (ASIC), a programmable logic device (PLD), or a field-programmable gate array (FPGA). Alternatively, the processor 331 is a combination of a plurality of these. The processor 331 may also be a combination of these with a hardware accelerator or the like. The processor 331 controls each unit to realize various functions of the server 3 based on programs such as firmware, system software, and application software stored in the ROM 332, the RAM 333, or an auxiliary storage device that is a part of the storage unit 31. Note that a part or all of the programs may be incorporated in the circuit of the processor 331.

[0039] The storage unit 31 is a storage area for various programs for causing the hardware group to function as the server 3, various data, etc., and can be configured with a ROM, a RAM, a flash memory, a solid-state drive (SSD), a hard disk drive (HDD), etc. Specifically, the storage unit 31 stores programs for causing the computer 33 to execute each function of this embodiment, images acquired from the doctor's terminal 2, generated 3D data of the head, etc.

[0040] The communication unit 32 executes a process for the server 3 to communicate with the doctor's terminal 2 and other devices via the network. The communication unit 32 in this embodiment is configured to be capable of wireless communication between the doctor's terminal 2 and the server 3.

[0041] In this embodiment, the manufacturing terminal 4 has a common or similar hardware configuration to that described in FIG. 5. The target terminal 5 has a common or similar hardware configuration to that described in FIG.

[0042] <Functional configuration> Next, various functions realized by the hardware configuration of the server 3 will be described with reference to Fig. 6. As shown in Fig. 6, the server 3 includes a data acquisition unit 51, a severity calculation unit 52, an order management unit 53, a target helmet data management unit 54, a treatment period estimation unit 55, a target head circumference calculation unit 56, a slit width calculation unit 57, a patient data management unit 58, an application linkage unit 59, and an interaction means presentation unit 60 as functional units operating on a processor (processor 331).

[0043] The data acquisition unit 51 acquires 3D scan data (multiple images) uploaded from the doctor's terminal 2 and registers it in a patient database constructed in the storage unit 31. The manufacturer downloads the 3D scan data from the server 3 using the manufacturing terminal 4 and creates 3D data showing the actual shape of the head based on the downloaded image data. The data acquisition unit 51 also acquires 3D data of the subject 100 uploaded from the manufacturing terminal 4.

[0044] The severity calculation unit 52 calculates an index indicating the severity based on three reference points specified by the therapist for the 3D data of the actual head. The severity calculation unit 52 will be described with reference to Figs. 7 to 9. The three reference points are a nose reference point 101 based on the position of the nose, a left ear reference point 102 based on the position of the left ear, and a right ear reference point 103 based on the position of the right ear. The three reference points are specified by the therapist for the 3D data of the actual head of the subject 100.

[0045] Fig. 7 shows an example of a display of a three-reference-point specification screen including 3D data of an actual head. In the example of Fig. 7, a 3D data display section 401, a six-plane display section 402, a cross-sectional display section 403, and a numerical value display section 404 are shown.

[0046] The 3D data display unit 401 displays 3D data showing the actual shape of the head. The therapist can specify three reference points on the 3D data display unit 401. For example, the therapist can specify the three reference points by clicking on the points showing the three reference points on the display screen and moving the points to the specified part. Alternatively, the processor 331 may specify the three reference points by automatically identifying the positions of the three reference points, without the therapist's involvement. The six-sided display unit 402 displays a six-sided view of the 3D data. The display of the three reference points specified by the therapist is also reflected in this six-sided view. The cross-sectional display unit 403 displays a cut surface of the head of the subject 100 cut on a third plane, which is the third plane from the bottom excluding the zeroth plane when the plane including the three reference points is set as the zeroth plane and the head is divided into ten parts up to the top of the head by a plane parallel to the zeroth plane. The third plane tends to have the largest head circumference among the ten-divided planes. The numerical value display unit 404 displays a table showing the numerical values ​​of each index calculated based on the specified three reference points and the numerical values ​​showing the shape of the head.

[0047] The calculation of various values ​​by the severity calculation unit 52 will be described. FIG. 8 is a diagram for explaining an example of a method for measuring the shape of the skull based on the three-point standard. As shown in FIG. 8, the severity calculation unit 52 draws a pair of first and second oblique lines OL1 and OL2 inclined at a predetermined angle θ1 from a nose center line (a line segment indicating the anterior-posterior diameter Ln of the head), which is a straight line connecting the nose reference point 101 and the skull center 104 and extending to the occipital side. The predetermined angle is, for example, 30 degrees. The severity calculation unit 52 calculates the intersection points of the first and second oblique lines OL1 and OL2 with the contour 105 of the head. The severity calculation unit 52 calculates the length L1 inside the contour 105 of the first oblique line OL1. The severity calculation unit 52 calculates the length L2 inside the contour 105 of the second oblique line OL2. The severity calculation unit 52 calculates the degree of deformation of the skull based on the difference between L1 and L2.

[0048] In this embodiment, the indices calculated by the severity calculation unit 52 are CA (Cranial Asymmetry), CVAI (Cranial Vault Asymmetry Index), and CI (Cephalic Index).

[0049] CA is an index that indicates the distortion (plagiocephaly) due to the difference in the shape of the head between the left and right sides. CA is calculated, for example, by the following formula 1. The unit is mm. [Formula 1] CA=|L1-L2|

[0050] CAVI is an index that indicates the degree of distortion (plagiocephaly degree) based on the plagiocephaly ratio. CAVI is calculated, for example, by the following formula 2. The unit is %. [Formula 2] CAVI=(L1-L2) / L2×100

[0051] CI is an index showing distortion (brachycephaly) based on the ratio of the head's left-right diameter Le to its front-to-back diameter Ln in a plane determined by three reference points. CI may also be used as an index showing the degree of flat head. CI is calculated, for example, by the following formula 3. The unit is %. [Formula 3] CI=Le / Ln×100

[0052] In the example of the numerical value display section 404 in Fig. 7, the numerical values ​​of the head shape (head circumference, left-right diameter, front-back diameter, etc.) in a plane determined by the three-point reference, each index such as CA, CVAI, and CI, the frontal symmetry rate, and the occipital symmetry rate are displayed. In addition, the corresponding measurement result is also displayed for each index. In this example, the measurement result of CI indicates normal, the measurement result of CA indicates moderate, and the measurement result of CVAI indicates moderate.

[0053] The severity calculation unit 52 can also display a graph plotting each calculated index on the doctor's terminal 2. The therapist can refer to the graph plotting each index to determine the severity of the subject 100 and consider a treatment plan. Fig. 9 is an example of a display showing a graph of the change in index indicating the distortion of the skull shape over the course of treatment. Fig. 9 shows a first graph display section 411 showing the change in plagiocephaly and a second graph display section 412 showing the change in brachycephaly.

[0054] The first graph display section 411 displays a graph with the number of days of treatment on the horizontal axis and the CVAI or CA on the vertical axis. In the example of FIG. 9, a graph with the CVAI on the vertical axis is displayed. The first graph display section 411 displays a predetermined range of CVAI (for example, a range of 0 to 20%) divided into multiple categories for each diagnostic information corresponding to the measurement results, such as most severe, severe, moderate, mild, and normal. By plotting the CVAI on the first graph display section 411, the therapist can easily and quickly determine the symptoms and treatment plan. In addition, the first graph display section 411 also plots indices based on regular 3D scan photography performed at monthly or twice-monthly examinations, so that the treatment effect can be easily understood from the change over time of the indices.

[0055] 9, the CVAI is plotted in the first graph display section 411, but a graph of CA can also be displayed by using the graph display switching section 413, which is an operation section for switching the display. In this case, too, the predetermined range of CA is displayed in a plurality of sections for each piece of diagnostic information corresponding to the measurement result.

[0056] The second graph display section 412 displays a graph with the number of days of treatment on the horizontal axis and the CI on the vertical axis. A predetermined range of CI (for example, a range of 70 to 120%) is displayed in the second graph display section 412 in a plurality of sections for each diagnostic information corresponding to the measurement results, such as severe, mild, and normal. By plotting the CI on the second graph display section 412, the therapist can easily and quickly determine the symptoms and treatment plan. Indicators based on regular 3D scan photography performed at monthly or twice-monthly examinations are also plotted on the second graph display section 412, so that the treatment effect can be easily understood from the change in the indicators over time.

[0057] The severity calculation unit 52 may output notification information to the doctor's terminal 2 to prompt the completion of the treatment of the subject 100 based on the indexes indicating the degree of plagiocephaly, such as CA and CVAI, and the index indicating the degree of brachycephaly, such as CI, which are information generated by the severity calculation unit 52. The notification information may be output as an image on a display such as the display unit 25, or may be output as a sound. The severity calculation unit 52 may be configured to output notification information indicating that the skull shape is severe to the doctor's terminal 2 when the calculated index exceeds a preset threshold value. In addition, the severity calculation unit 52 may output notification information to the doctor's terminal 2 to inform the subject 100 receiving treatment that the treatment may be completed if both the indexes indicating the degree of plagiocephaly and the index indicating the degree of brachycephaly are within the normal range for the first time after the start of treatment, if both the indexes are within the normal range again at the next examination. Then, when both the index indicating the degree of plagiocephaly and the index indicating the degree of brachycephaly are within the normal range in two consecutive examinations after the start of treatment, the severity calculation unit 52 may output notification information to the doctor's terminal 2 urging the doctor to complete the treatment and informing the doctor that continuous wearing of the cranial shape correcting helmet 7 is not recommended. This allows the doctor to easily grasp the appropriate timing to complete the treatment of the subject 100.

[0058] The order management unit 53 will be described with reference to Fig. 10. The order management unit 53 receives order information required for helmet production from a therapist, and notifies a manufacturer that a request for helmet production has been made based on the received order information.

[0059] Fig. 10 is a display example of an order screen displayed on the doctor's terminal 2 by the order management unit 53. The therapist places an order for the cranial shape correcting helmet 7 using the order screen as shown in Fig. 10. In the example of Fig. 10, an order information input section 421, a helmet pattern designation section 422, and an order form creation instruction section 423 are shown.

[0060] The order information input unit 421 is an operation unit that accepts input of information required for ordering, such as patient ID, name of person in charge, email address, gestational age, type of helmet, delivery date, planned date of wearing, etc. The helmet pattern designation unit 422 is an operation unit that presents images showing helmet patterns as options and accepts the selected image as order information indicating the designation of the helmet pattern. The order sheet creation instruction unit 423 is an operation unit that accepts an instruction to create an electronic order sheet based on the input contents of the order information input unit 421 and the selection contents of the helmet pattern designation unit 422.

[0061] The target helmet data management unit 54 will be described with reference to Fig. 11 and Fig. 12. The target helmet data management unit 54 acquires target data and helmet data created based on 3D data showing the actual shape of the head. The target helmet data management unit 54 provides the target data and helmet data to the therapist in response to a viewing request from the doctor's terminal 2. The target helmet data management unit 54 of this embodiment acquires the target data and helmet data uploaded from the manufacturer's terminal 4, and displays a confirmation screen for allowing the doctor's terminal 2 to confirm the target data and a confirmation screen for allowing the doctor's terminal 2 to confirm the helmet data.

[0062] Fig. 11 is a display example of a confirmation screen for target data displayed on the doctor's terminal 2 by the target helmet data management unit 54. The therapist judges the validity of the target data through the confirmation screen as shown in Fig. 11. On the confirmation screen shown in Fig. 11, 3D data of the actual head shape and target data showing the ideal head shape are displayed superimposed on each other.

[0063] In the example of Figure 11, a three-dimensional display section 501, a six-sided display section 502, a cross-sectional display section 503, a cutting position change section 504, a data A display section 505, a data B display section 506, a display switching section 507, a confirmation point display section 508, and a correction selection section 509 are displayed to visually check the head shape.

[0064] The stereoscopic display unit 501 is a display unit for checking the orientation of the head from an oblique angle, with 3D data and target data superimposed, and the display orientation can be changed by operating the doctor's terminal 2. The six-sided display unit 502 is a display unit for showing six-sided views of the head, with 3D data and target data superimposed. The cross-sectional display unit 503 is a cutting plane based on three-point reference, and the display position of the cutting plane can be changed by the cutting position change unit 504. The data A display unit 505 shows the numerical values ​​of the actual head shape (3D data), and the data B display unit 506 shows the numerical values ​​of the ideal head shape (target data).

[0065] The display switching unit 507 is an operation unit that changes the display mode, allowing switching between display of 3D data (data A), display of target data (data B), and transparent display. The confirmation point display unit 508 displays the judgment criteria for confirming validity in text. The confirmation point display unit 508 shows the judgment criteria for the index values ​​of CI and CIAV and the judgment criteria for the shape of the target data. The correction selection unit 509 is an operation unit that allows the therapist to select the validity of the target data through the doctor's terminal 2. If the therapist judges that the target data is valid, he / she selects "OK" in the correction selection unit 509, and if the target data needs to be corrected, he / she selects "requires correction". The selection result can be confirmed by the manufacturer through the manufacturer's terminal 4.

[0066] Fig. 12 is an example of a confirmation screen of helmet data displayed on the doctor's terminal 2 by the target helmet data management unit 54. The therapist judges the validity of the helmet data through the confirmation screen as shown in Fig. 12. In the confirmation screen shown in Fig. 12, 3D data of the actual head shape and helmet data to be manufactured are displayed superimposed. Note that judging the validity of the helmet data means judging whether the size, shape, etc. of the cranial correction helmet indicated by the helmet data are suitable for head treatment from the 3D data indicating the actual head shape to the target data.

[0067] In the example of FIG. 12, a three-dimensional display section 601, a six-sided display section 602, a cross-sectional display section 603, a cutting position change section 604, a confirmation point display section 608, and a correction selection section 609 are displayed to visually check the head shape.

[0068] The stereoscopic display section 601 is a display section for checking the orientation of the head from an oblique angle, with the 3D data and helmet data superimposed, and the display orientation can be changed by operating the doctor's terminal 2. The six-sided display section 602 is a display section for a six-sided view of the head, with the 3D data and helmet data superimposed. The cross-sectional display section 603 is a cut surface based on three points, and displays the cut surface of the helmet data together with the head. The display position of the cut surface in this cross-sectional display section 603 can also be changed by a cut position change section 604. The example in FIG. 12 also shows a scan data display section 605 that shows numerical values ​​of the actual head shape.

[0069] The confirmation point display area 608 shows in text the judgment criteria based on the positional relationship of the head and face parts to the helmet. This is an operation area that enables the therapist to select the validity of the helmet data through the doctor's terminal 2. If the therapist judges the helmet data to be valid, he or she selects "OK" in the correction selection area 609, and if the helmet data needs correction, he or she selects "Correction required". The selection result can be confirmed by the manufacturer through the manufacturer's terminal 4.

[0070] Next, a method for estimating a treatment period by the treatment period estimation unit 55 will be described with reference to Figures 13 and 14. The treatment period estimation unit 55 of this embodiment estimates a treatment period required for the current head circumference to reach the head circumference of the target data.

[0071] FIG. 13 is a schematic diagram showing the relationship between the head circumference of 3D data showing the actual head shape and the head circumference of the target data. FIG. 14 is a graph showing the relationship between the head circumference growth curve and the head circumference of the target data. The horizontal axis of the graph in FIG. 14 is age in months, and the vertical axis is head circumference according to age in months. The curve in the graph is a head circumference growth curve showing the average theoretical head circumference that changes with age in months. For the head circumference growth curve, data issued by a public institution such as the Ministry of Health, Labor and Welfare can be used.

[0072] As shown in FIG. 13, if the head circumference of the target data is M and the head circumference of the 3D data showing the actual head shape (hereinafter also referred to as 3D model head circumference) is S, the grown head circumference D can be calculated using the following formula 4. [Formula 4] D=MS

[0073] The growth rate of infants and children varies greatly depending on their age. Therefore, the treatment period estimation unit 55 calculates the period required for the theoretical head circumference A on the head circumference growth curve at the scan age photographed by the doctor's terminal 2 to grow to the growth head circumference D as the estimated treatment period, instead of the age at which the head circumference M of the target data will be reached.

[0074] A calculation method using the head circumference growth curve in Fig. 14 will be specifically described. In this embodiment, an equation that approximates the curve of the average value for men and women using a power series is used. Head circumference can be calculated using the following Equation 5. Age in months can be calculated from Equation 5 as shown in Equation 6. [Formula 5] Head circumference = 365 × age in months^t (approximation coefficient) [Formula 6] Age in months = e^(ln(head circumference / 365) / t(approximation coefficient))

[0075] The theoretical head circumference A on the head circumference growth curve is calculated by substituting the scan age into the "age in months" of the formula 5. As described above, the theoretical head circumference A is added to the growth head circumference D to calculate the theoretical target head circumference Bt on the head circumference growth curve. The theoretical target head circumference Bt is substituted into the "head circumference" of the formula 6 to calculate the estimated treatment end age. The estimated treatment end age indicates the age at which the theoretical target head circumference Bt is reached on the head circumference growth curve. Since the estimated treatment end age is a numerical value indicating the age at which treatment ends, the estimated treatment period is finally calculated by subtracting the scan age from the estimated treatment end age. That is, the treatment period estimation unit 55 of this embodiment estimates the treatment period required for correcting the skull shape of the infant as the subject 100 based on the current head circumference measurement result, the head circumference of the target data, and the head circumference growth curve. More specifically, the treatment period estimation unit 55 estimates the treatment period required to correct the infant's skull shape based on the difference (grown head circumference D) between the current head circumference (3D model head circumference S) and the head circumference of the target data (head circumference M of the target data), and the head circumference on the head circumference growth curve at the current age in months.

[0076] Next, the target head circumference calculation unit 56 will be described with reference to Fig. 15 and Fig. 16. The target head circumference calculation unit 56 calculates the head circumference of target data taking into account the growth of the subject 100 until the delivery date when the cranial shape correcting helmet 7 is actually delivered to the subject 100 (hereinafter referred to as the target head circumference). The delivery date can also be called the planned date of wearing or the planned date of receipt by the subject 100. The head circumference growth curve is also used in calculating the target head circumference taking into account this delivery date.

[0077] FIG. 15 is a schematic diagram showing the relationship between the head circumference of the target data without taking into account the delivery date and the target head circumference with the delivery date taken into account. There is a waiting period for manufacturing, shipping, etc. until the skull shape correction helmet 7 actually arrives to the subject 100. Since the head circumference of an infant changes depending on the age of the infant, even if the waiting period is about two weeks, the head circumference is likely to change from the above-mentioned scan age. As shown in FIG. 15, it is preferable to set the target head circumference T taking into account the growth.

[0078] FIG. 16 is a graph showing the relationship between the head circumference growth curve and the target head circumference taking into account the delivery date. The horizontal axis of the graph in FIG. 16 is age in months, and the vertical axis is head circumference according to age in months. As shown in FIG. 16, the target head circumference calculation unit 56 calculates theoretical head circumference A on the head circumference growth curve by substituting the scan age for "age in months" in formula 5. Next, the value obtained by adding the number of days to delivery to the scan age is substituted for "age in months" in formula 5 to calculate theoretical head circumference B at the time of delivery. Note that the number of days to delivery in formula 5 is calculated by adjusting the unit to the age in months.

[0079] The theoretical growth head circumference Dt can be calculated by the following formula 7. The theoretical growth head circumference Dt is added to the head circumference M of the target data to calculate the target head circumference T taking the delivery date into consideration. If the head circumference of the target data is M and the theoretical growth head circumference is Dt, the target head circumference T can be calculated by the following formula 8. In this manner, in this embodiment, the target head circumference calculation unit 56 calculates the target head circumference T taking the delivery date into consideration. That is, the target head circumference calculation unit 56 of this embodiment calculates the target head circumference taking into consideration the growth of the subject 100 until the delivery date based on the difference between the head circumference on the head circumference growth line at the current age (theoretical head circumference A) and the head circumference on the head circumference growth line at the age at the time of delivery (theoretical head circumference B), and the head circumference of the target data. [Formula 7] Dt=BA [Formula 8] T=M+Dt

[0080] Next, the slit width calculation unit 57 will be described with reference to Fig. 17. When the skull shape correction helmet 7 is worn for a long time, the correction force of the skull shape correction helmet 7 causes the head's minor axis A1 (corresponding to OL1 in Fig. 8) to grow, but the length of the major axis B1 (corresponding to OL2 in Fig. 8) does not grow. However, when the skull shape correction helmet 7 is worn for a short time, the minor axis A1 and major axis B1 may grow to the minor axis A2 and major axis B2 (A1 <A2、B1<B2)。

[0081] The cranial shape corrective helmet 7 is manufactured in anticipation of the growth of the subject 100, so even if the circumferential length of the head is set so that no gap occurs when the helmet is worn, the head accommodation space Sp can be expanded according to growth (see FIG. 3). In the example of FIG. 17, the slit width d is generated due to the growth of the long axis B2 of the head.

[0082] The slit width calculation unit 57 calculates the slit width d based on the elongation of the long axis (B1, B2) of the head, which affects the shape of the cranial shape correcting helmet 7 when worn. In this embodiment, the slit width calculation unit 57 approximates the circumference as 2πr, and calculates the slit width d using the following formula 9 based on the elongated length of the long axis. [Formula 9] d=(B2-B1)×π

[0083] The slit width calculation unit 57 outputs notification information according to the slit width d based on information about the slit width d generated by itself. For example, the slit width calculation unit 57 can be set to have a function of outputting notification information to the doctor's terminal 2 or the manufacturer's terminal 4 informing the prohibition of use of the cranial shape correction helmet 7 when the slit width d is equal to or greater than a preset limit threshold (for example, 15 mm). When the slit width d exceeds the threshold, the cranial shape correction helmet 7 being worn may not match the shape of the head of the grown subject 100. In this case, it is necessary to remake the cranial shape correction helmet 7 based on new 3D data indicating the shape of the head of the subject 100. The therapist or manufacturer can appropriately grasp the timing to remake the cranial shape correction helmet 7 by using the function of outputting an alert. The slit width calculation unit 57 may output the slit width d generated by itself to the subject's terminal 5 as notification information.

[0084] When the slit width d is other than 0, the slit width calculation unit 57 may output to at least one of the doctor's terminal 2 and the subject's terminal 5 notification information informing the subject 100 that the time the cranial shape correction helmet 7 has been worn may be short and notification information encouraging the subject 100 to check whether there is a problem with the wearing of the cranial shape correction helmet 7. This allows the therapist to encourage the subject 100 or a person related to the subject 100 to keep to the wearing time of the cranial shape correction helmet 7 and to ask about the wearing status at an appropriate time. Furthermore, when there is a problem with the wearing of the cranial shape correction helmet 7, the subject 100 or a person related to the subject 100 can recognize the need to improve the wearing at an appropriate time.

[0085] When the head circumference is equal to or larger than the head circumference M of the target data or equal to or larger than the target head circumference T, and the slit width d of the cranial shape correction helmet 7 worn by the subject 100 is equal to or larger than a predetermined threshold value (e.g., 10 mm), the server 3 may output notification information to the doctor's terminal 2 indicating that the cranial shape correction helmet 7 may reach its wearing limit. This allows the therapist to know in advance that the time to replace the cranial shape correction helmet 7 or to complete the treatment of the subject 100 is approaching, allowing for safer treatment.

[0086] When the head circumference is equal to or larger than the head circumference M of the target data or equal to or larger than the target head circumference T, and the slit width d of the cranial shape correction helmet 7 worn by the subject 100 is equal to or larger than a predetermined threshold value (e.g., 15 mm), the server 3 may output notification information to the doctor's terminal 2 informing the prohibition of use of the cranial shape correction helmet 7. This allows the therapist to easily grasp the appropriate timing for replacing the cranial shape correction helmet 7 or for completing the treatment of the subject 100.

[0087] The server 3 may output notification information based on the condition of the scalp shown in the image of the subject's 100's head after the start of treatment. Specifically, when the server 3 determines that there is redness or a bedsore on the scalp shown in the image of the subject's 100's head acquired from the subject's terminal 5, the server 3 may output notification information that prompts the confirmation of the condition of the skin trouble or the treatment of the skin trouble. This allows the subject 100 or a person related to the subject 100 to ask the therapist to confirm the symptoms at any time when a worrying symptom such as redness or a bedsore occurs on the subject's 100's head, and the therapist can promptly confirm the symptoms.

[0088] The server 3 may output notification information based on the 3D data showing the shape of the head of the subject 100 after the start of treatment and the head circumference growth curve. For example, the server 3 may output notification information encouraging the subject 100 to continue using the cranial shape correction helmet 7 when the head circumference is not out of line with the head circumference growth curve and the head circumference growth is equal to or less than a predetermined threshold. In addition, for example, the server 3 may output notification information encouraging the subject 100 to check whether there is a possibility other than positional cranial deformity when the head circumference of the subject 100 is out of line with the head circumference growth curve. This allows the therapist to easily grasp the timing when it is necessary to check the treatment status based on more accurate information on the treatment status of the cranial shape.

[0089] Next, the patient data management unit 58 will be described with reference to Fig. 18. The patient data management unit 58 acquires and presents various pieces of information relating to the patient to the doctor terminal 2, the manufacturer terminal 4, or the patient terminal 5.

[0090] Fig. 18 is a display example of detailed patient data displayed on the doctor's terminal 2 by the patient data management unit 58. As shown in Fig. 18, the patient data management unit 58 can display various types of information related to the patient on the doctor's terminal 2. In the example of Fig. 18, a patient information display unit 701 and an imaging information display unit 702 are shown.

[0091] The patient information display unit 701 displays various information such as the patient ID, sex, date of birth, age in months, gestational age, status display (under treatment, ordered, etc.), delivery date of the cranial shape correction helmet 7, planned fitting date, color of the cranial shape correction helmet 7, age in months of first scan, age in months of starting treatment, number of months of treatment / estimated treatment period, current head circumference / estimated target head circumference, etc. When the planned fitting date is entered, information indicating how many days have passed since the first scan is added. The display items for these various pieces of information may be specified on the server 3 side according to access restrictions.

[0092] Among the items displayed on the patient information display unit 701, the age at start of treatment indicates the age in months on the scheduled date of fitting, the number of months of treatment / estimated treatment period indicates the treatment period to reach the target data head circumference, and the current head circumference / estimated target head circumference etc. indicate the target head circumference taking into account growth up to the delivery date.

[0093] The imaging information display unit 702 displays various information such as imaging date, head circumference, left-right diameter, front-back diameter, CI, CA, CVAI, long axis, slit width, memo, etc. The imaging information display unit 702 also includes display instruction units such as "Scan" for displaying an image of 3D data, "Target" for displaying an image of target data, and "Helmet" for displaying an image of helmet data. The imaging information display unit 702 also includes "+Image" as an addition instruction unit for adding a captured image or 3D data.

[0094] Next, the application linking unit 59 will be described with reference to Fig. 19 to Fig. 21. The application linking unit 59 links various information with the application installed in the subject terminal 5. Hereinafter, the application installed in the subject terminal 5 will be described as a treatment record application.

[0095] Fig. 19 is a display example of a wearing time screen of the treatment record application of the subject terminal 5. In the example of Fig. 19, a wearing time display section 810, a wearing time graph display section 811, a subject display section 812, and an entry section 813 are shown.

[0096] The wearing time display unit 810 displays numerical values ​​indicating the wearing time of the subject 100, such as the wearing time today, the wearing time yesterday, the number of days of wearing, the average wearing time per day, and the total wearing time. The wearing time graph display unit 811 displays the wearing record for a predetermined number of days in the past (e.g., 30 days) in a graph (e.g., a line graph) showing the relationship between the number of days and time. The subject display unit 812 displays an image of the subject 100. The subject display unit 812 displays display images uploaded by the subject 100 or a person related to the subject 100.

[0097] The entry section 813 is a section that accepts input of information related to the wearing time of the subject 100 by the operator of the subject terminal 5. Information related to the wearing time includes information such as the wearing start time, the wearing end time, memos, and images. The operator of the subject terminal 5 can tap the entry section 813 to launch an input window, and input information related to the wearing time into the input window.

[0098] In this way, the subject 100 or a person related to the subject 100 (guardian) can input the wearing time of the cranial shape correction helmet 7 to the server 3 via the subject's terminal 5. If the wearing time per day is short, the treatment may not be effective. In the prior art, it was difficult for the therapist to grasp the wearing time of the subject 100, and it was sometimes impossible to determine whether the lack of effect was due to the wearing time or a problem with the shape of the cranial shape correction helmet 7. In this regard, according to this embodiment, the therapist can obtain the wearing time of the patient from the server 3 via the doctor's terminal 2.

[0099] If the input wearing time is inappropriate, the therapist can input to the server 3 from the doctor's terminal 2 that the wearing time is inappropriate. The input information is associated with the subject 100 and registered in the patient database. Furthermore, if the wearing time input by the subject 100 or a person related to the subject 100 is inappropriate, the server 3 may notify the therapist by alerting that the wearing time is inappropriate. Furthermore, the subject 100 or a person related to the subject 100 may be notified by alert on the subject's terminal 5 via a treatment record app or the like that the wearing time is inappropriate.

[0100] Fig. 20 is a display example of a treatment progress graph of the treatment record app of the subject terminal 5. In the example of Fig. 20, a plagiocephaly graph display section 821, a brachycephaly graph display section 822, a next examination date display section 823, a display selection section 824, and an entry section 813 are shown.

[0101] The plagiocephaly graph display section 821 displays a graph similar to that of the first graph display section 411 described in Fig. 9, and the brachycephaly graph display section 822 displays a graph similar to that of the second graph display section 412 described in Fig. 9. The next examination date display section 823 displays the next examination date. The next examination date can be input by operating the subject terminal 5. The display selection section 824 is an operation section for selecting the display content from a summary screen showing the treatment progress, a 3D data screen, and a helmet screen. In Fig. 20, summary is selected.

[0102] Fig. 21 is a display example of 3D data of the treatment record application of the subject terminal 5. In the example of Fig. 21, a 3D data display section 831, an imaging date selection section 832, a next examination date display section 823, a display selection section 824, and an entry section 813 are shown.

[0103] The 3D data display section 831 displays a 3D model in which the head shape of the subject 100 and an ideal head shape based on the target data are superimposed. The imaging date selection section 832 is an operation section for selecting 3D data to be displayed based on the imaging date. When the date portion of the imaging date selection section 832 is selected, a 3D model in which the head shape of the subject 100 based on the 3D scan imaging on the selected date and the ideal head shape based on the target data are superimposed is displayed. The next examination date display section 823, the display selection section 824, and the entry section 813 are the same as those described in Figs. 19 and 20. In Fig. 21, the display of 3D data showing the actual head shape by the 3D data display section 831 is selected.

[0104] Next, the dialogue means presenting unit 60 will be described. The dialogue means presenting unit 60 provides a chat-style dialogue means between the doctor's terminal 2 and the subject's terminal 5. The dialogue means presenting unit 60 may provide a chat-style dialogue means on a treatment record application. The dialogue means provided by the dialogue means presenting unit 60 allows the subject 100 or the guardian of the subject 100 to ask questions to the therapist, and the therapist can also communicate the treatment policy, etc. to the subject 100. For example, the therapist can input instructions to the patient based on the wearing time.

[0105] The dialogue means presentation unit 60 also provides a chat-style dialogue means between the doctor terminal 2 and the manufacturer terminal 4. The dialogue means provided by the dialogue means presentation unit 60 allows the therapist and manufacturer to exchange information about 3D data, how to use the helmet, how to deal with problems, and the like.

[0106] <Processing flow> Next, the flow of management processing by the cranial shape correcting helmet management system 1 will be described with reference to Fig. 22 to Fig. 26. Fig. 22 to Fig. 26 are flow diagrams showing the flow of management processing for managing the cranial shape correcting helmet 7. The flows shown in Fig. 22 to Fig. 26 are merely examples of processing, but each flow is continuous according to the diagram numbers and step numbers.

[0107] In step S1, the doctor's terminal 2 accepts input of patient information by the doctor and outputs the accepted patient information to the server 3. For example, the patient information is the patient's name, date of birth, medical history, etc. In step S2, the patient data management unit 58 of the server 3 registers the patient information input from the doctor's terminal 2 in a patient database constructed in the storage unit 31.

[0108] In step S3, the doctor's terminal 2 acquires image data of the 3D scan performed on the patient. In step S4, the doctor's terminal 2 uploads the acquired 3D scan image data to the server 3. In step S5, the data acquisition unit 51 of the server 3 associates the 3D scan image data input from the doctor's terminal 2 with the patient and registers it in the patient database.

[0109] In step S6, the manufacturing side terminal 4 downloads and acquires the image data of the 3D scan from the server 3. In step S7, the manufacturing side terminal 4 acquires 3D data created based on the image data of the 3D scan. The 3D data is created, for example, on the manufacturing side terminal 4. In step S8, the manufacturing side terminal 4 uploads the created 3D data to the server 3. In step S9, the data acquisition unit 51 of the server 3 acquires the uploaded 3D data. The acquired 3D data is associated with the subject 100 and registered in the patient database.

[0110] In step S10, the doctor's terminal 2 outputs designation information that designates three reference points (nose reference point 101, left ear reference point 102, and right ear reference point 103) for the 3D data to the server 3. For example, the therapist makes a request to the server 3 to view the 3D data, causing the doctor's terminal 2 to display the three reference points designation screen of FIG. 7. The therapist operates the doctor's terminal 2 to designate the three reference points designation screen. As a result, the three reference points are registered in the patient database of the server 3. In step S11, the severity calculation unit 52 calculates the severity and each index based on the designation information designated by the therapist. The severity and each index calculated by the severity calculation unit 52 are associated with the subject 100 and registered in the patient database.

[0111] In step S12, the doctor's terminal 2 displays information necessary for making a decision, such as the numerical display section 404 of the three-point reference designation screen in Fig. 7 and the graph showing the indexes in Fig. 9. The therapist checks the information displayed on the doctor's terminal 2 and decides whether or not the cranial shape correction helmet 7 is suitable for the subject 100. If the therapist decides that the cranial shape correction helmet 7 is suitable, in step S13, he or she causes the doctor's terminal 2 to display the order screen of Fig. 10, and inputs information necessary for ordering the cranial shape correction helmet 7, such as patient information, color, delivery date, etc., on the order screen. In step S14, the order management section 53 of the server 3 outputs information regarding the electronic contract based on the received order information to the manufacturer's terminal 4.

[0112] In step S15, the manufacturer creates target data on the manufacturing terminal 4 based on the order information and 3D data indicating the actual head shape. In step S16, the manufacturer creates helmet data indicating the shape of the helmet based on the target data on the manufacturing terminal 4. In step S17, the manufacturing terminal 4 uploads the target data and helmet data to the server 3. In step S18, the data acquisition unit 51 of the server 3 registers the target data and helmet data uploaded by the manufacturing terminal 4 in the patient database in association with the patient.

[0113] In step S19, the doctor's terminal 2 outputs a viewing request to the server 3, and displays the target data confirmation screen of Fig. 11 and the helmet data confirmation screen of Fig. 12. The therapist inputs the confirmation results on the confirmation screen. In step S20, the patient data management unit 58 of the server 3 accepts the target data and helmet data confirmation results from the doctor's terminal 2, and registers the confirmation results in the patient database. The confirmation results are also output from the server 3 to the manufacturer's terminal 4.

[0114] If the confirmation result is NG or otherwise requires correction, in step S21, the manufacturer corrects the target data and helmet data on the manufacturing terminal 4. In step S22, the manufacturing terminal 4 uploads the corrected target data and helmet data to the server 3. In step S23, the data acquisition unit 51 of the server 3 registers the corrected target data and helmet data in the patient database in association with the patient.

[0115] In step S24, the doctor's terminal 2 outputs a viewing request to the server 3 and displays a confirmation screen for the corrected target data and helmet data. The therapist inputs the confirmation results on the confirmation screen. In step S25, the patient data management unit 58 of the server 3 accepts the confirmation results of the target data and helmet data from the doctor's terminal 2 and registers the confirmation results in the patient database. If there are no problems with the confirmation results, in step S26, the treatment period estimation unit 55 estimates the treatment period and the target head circumference calculation unit 56 calculates the target head circumference.

[0116] Here, the flow from the manufacture to delivery of the cranial shape correction helmet 7 that is actually manufactured will be described. The flow from the manufacture to delivery of the cranial shape correction helmet 7 will be described with reference to the block surrounded by a dashed line in FIG. 24. The manufacturer actually manufactures the cranial shape correction helmet 7 based on the target data and helmet data confirmed by the therapist. The cranial shape correction helmet 7 is manufactured, for example, by a 3D printer. Next, the manufacturer ships the cranial shape correction helmet 7 to the therapist, who actually receives it. The therapist hands the cranial shape correction helmet 7 to the subject 100 by handing it over when the therapist visits or by shipping it. The subject 100 wears the received cranial shape correction helmet 7.

[0117] In step S27, the application linking unit 59 of the server 3 creates a QR code (registered trademark) for linking various information to the subject terminal 5, and outputs it to the doctor's terminal 2. In step S28, the doctor's terminal 2 prints the QR code input from the server 3 by a printer (not shown). The printed QR code is handed over or shipped to the subject 100 in the same manner as the cranial shape correcting helmet 7.

[0118] In step S29, the subject 100 downloads the treatment record app by operating the subject terminal 5. In step S30, the treatment record app is installed in the subject terminal 5, and patient information is registered in the treatment record app. In step S31, the subject 100 operates the subject terminal 5 to read the QR code provided by the therapist.

[0119] In step S32, the subject terminal 5 reads the QR code and outputs app linkage information indicating that linkage processing of the treatment record app has been performed to the server 3. In step S33, the app linkage unit 59 of the server 3 registers the app linkage information input from the subject terminal 5 and links various information registered in the treatment record app and the patient database of the server 3. In step S34, the subject terminal 5 is in a state where it can display the severity and each index using the linked treatment record app. In step S35, the subject terminal 5 is in a state where it can display the goal data and helmet data using the linked treatment record app.

[0120] In step S36, when the subject terminal 5 receives information such as the time the subject 100 has worn the cranial shape corrective helmet 7 and images of the subject 100 in a worn state and an unworn state, the subject terminal 5 registers the received information in the treatment record application and outputs it to the server 3. The images of the worn state are used, for example, by the therapist to check how the subject 100 is wearing the cranial shape corrective helmet 7. The images of the unworn state are used, for example, by the therapist to check for abnormalities in the subject 100, such as reddening of the skin.

[0121] In step S37, the subject terminal 5 is in a state where the wearing time and images can be displayed by the treatment record application. In step S38, the subject terminal 5 is in a state where summary data related to treatment (see FIG. 19) can be displayed by the treatment record application. In step S39, the patient data management unit 58 of the server 3 registers the information such as the wearing time and images input from the subject terminal 5 in the patient database in association with the patient.

[0122] In step S40, the doctor terminal 2 acquires image data of the 3D scan performed on the patient during a monthly examination. In step S41, the doctor terminal 2 uploads the acquired 3D scan image data to the server 3. In step S42, the data acquisition unit 51 of the server 3 associates the 3D scan image data input from the doctor terminal 2 with the patient and registers it in the patient database.

[0123] In step S43, the manufacturing terminal 4 downloads and acquires the image data of the 3D scan from the server 3. In step S44, the manufacturing terminal 4 acquires newly created 3D data based on the image data of the 3D scan acquired in step S43. In step S45, the manufacturing terminal 4 uploads the created 3D data to the server 3. In step S46, the data acquisition unit 51 of the server 3 acquires the uploaded 3D data and registers it in association with the patient database. In step S47, the application linking unit 59 links with the treatment record application to enable the newly created 3D data to be displayed on the subject terminal 5.

[0124] In step S48, the doctor's terminal 2 outputs to the server 3 the designation information that designates three reference points for the 3D data. In step S49, the severity calculation unit 52 calculates the severity and each index based on the designation information designated by the therapist. The calculated severity and each index are registered in the patient database. In step S50, the application linkage unit 59 links with the treatment record application to enable the newly created severity and each index to be displayed on the subject terminal 5. In step S51, the patient data management unit 58 creates a graph showing the treatment progress. In step S52, the application linkage unit 59 links with the treatment record application to enable the newly created graph to be displayed on the subject terminal 5. In step S53, the slit width calculation unit 57 calculates the expected slit width d. In step S54, the application linkage unit 59 links with the treatment record application to enable the newly created slit width d to be displayed on the subject terminal 5.

[0125] In step S55, the patient data management unit 58 creates a treatment progress report based on a predetermined format, and outputs the created treatment progress report to the manufacturing terminal 4. In step S56, the manufacturing terminal 4 prints the treatment progress report created by the patient data management unit 58 of the server 3 by a printer.

[0126] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified as appropriate.

[0127] According to the embodiment and the modified examples described above, the following effects are achieved.

[0128] (1) The cranial shape correction helmet management system 1 comprises a doctor's terminal 2 used by a therapist treating the cranial shape of the subject 100, a manufacturing terminal 4 used by a manufacturer of the cranial shape correction helmet 7 to be worn on the head of the subject 100 to correct the cranial shape of the subject 100 based on multiple images of the subject's 100's head taken by the therapist, and a server 3 that inputs and outputs helmet information and multiple images related to the cranial shape correction helmet 7 between the doctor's terminal 2 and the manufacturing terminal 4.

[0129] As a result, the therapist uploads an image of the head of the subject 100 to the server 3 through the doctor's terminal 2, and the manufacturer can easily download the image of the head of the subject 100 through the manufacturer's terminal 4. In addition, the manufacturer can upload helmet information such as 3D data, target data, and helmet data created based on the image of the head of the subject 100 to the server 3. As a result, the therapist can check the shape of the cranial shape correction helmet 7 in the pre-manufacturing stage on the cloud (server 3), and can easily give instructions to the manufacturer for corrections, etc. Furthermore, since the information uploaded or input by the doctor's terminal 2 or the manufacturer's terminal 4 can be managed by the server 3, the doctor's terminal 2 or the manufacturer's terminal 4 does not need to build a database for managing the information of the subject 100 by itself, and management costs can be reduced. In this way, the configuration of this embodiment can realize the efficient exchange of data related to the cranial shape correction helmet 7 between the therapist and the manufacturer and the efficient data management.

[0130] (2) In the cranial shape correction helmet management system 1 described in (1), the server 3 inputs and outputs treatment period information regarding the estimated treatment period required to correct the cranial shape of the subject 100 between the doctor's terminal 2 and the manufacturer's terminal 4.

[0131] This allows the therapist or manufacturer to obtain the estimated treatment period without having to calculate it themselves, based on the information output from the server 3. Using the estimated treatment period also makes it easier to predict changes in the head caused by growth during the treatment period, and makes it possible to efficiently manufacture the cranial shape correction helmet 7 that takes into account future changes in head shape.

[0132] (3) In the cranial shape correction helmet management system 1 described in (1), the subject 100 is an infant, and the treatment period information is estimated based on the current head circumference of the subject 100, the head circumference of target data indicating the ideal head shape of the subject 100, and a head circumference growth curve indicating the average head circumference that changes with the infant's age.

[0133] This allows the treatment period to be estimated taking into account the head circumference growth curve, making it possible to estimate and share a more accurate treatment period even for infants and young children, whose head circumference changes in a short period of time.

[0134] (4) The cranial shape correction helmet management system 1 described in any of (1) to (3) further includes a subject terminal 5 used by the subject 100, the cranial shape correction helmet 7 is capable of adjusting the size of the head accommodating space Sp that accommodates the head, the helmet information includes a slit width d as size information regarding the size of the head accommodating space Sp suitable for the subject 100, and the subject terminal 5 is capable of acquiring the size information from the server 3.

[0135] This allows the subject 100 and those related to the subject 100 to understand the appropriate slit width d without having to undergo a medical examination, etc., making it easy to wear the cranial shape correction helmet 7 with the appropriate slit width d.

[0136] (5) In the cranial shape correction helmet management system 1 described in (4), the slit width d as size information is information determined based on helmet data indicating the shape of the cranial shape correction helmet 7 to be worn by the subject 100 and 3D data indicating the shape of the subject 100's head after treatment begins.

[0137] This allows the slit width d to be calculated accurately based on the shape of the head after treatment has started (after a predetermined period has elapsed), thereby achieving higher wearability.

[0138] (6) In the cranial shape corrective helmet management system 1 described in any one of (1) to (5), the server 3 outputs notification information based on the acquired information or information generated by the server 3 itself.

[0139] This allows the therapist, manufacturer, subject 100, or related parties of subject 100 to understand the status of the cranial shape correction helmet and treatment at the appropriate time.

[0140] (7) In the cranial shape correction helmet management system 1 described in any one of (1) to (6), the system further includes a subject terminal 5 used by the subject 100 or a person related to the subject 100, and the server 3 provides a chat-style communication means between the doctor's terminal 2 and the manufacturer's terminal 4 and between the doctor's terminal 2 and the subject's terminal 5.

[0141] This enables real-time sharing and exchange of information regarding the cranial shape correction helmet 7 between the therapist and the manufacturer, and information regarding treatment between the therapist and the subject 100 or a person related to the subject 100.

[0142] (8) In the cranial shape correction helmet management system 1 described in any one of (1) to (7), the server 3 outputs an operation unit to the doctor's terminal 2 for the therapist to select the validity of at least one of the helmet information and the shape data, obtains the selection result of the validity selected through the operation unit output to the doctor's terminal 2, and outputs it to the manufacturing terminal 4.

[0143] This allows the therapist to select the appropriateness of the shape data uploaded by the manufacturer to the server 3 and the cranial shape correction helmet 7 at the pre-manufacturing stage on the cloud (server 3), and the manufacturer can check the selection result by the therapist, i.e., the need for corrections to the data from the therapist, on the cloud. This eliminates the need for complicated processes such as email correspondence between the therapist and the manufacturer, and allows the work to proceed smoothly from data confirmation to manufacturing.

[0144] (9) The cranial shape correction helmet management method has a computer (server 3) execute a process for inputting and outputting helmet information and shape data regarding the cranial shape correction helmet 7 between a doctor's terminal 2 used by a therapist treating the cranial shape of the subject 100, and a manufacturer's terminal 4 used by a manufacturer of the cranial shape correction helmet 7 to be worn on the head of the subject 100 to correct the cranial shape of the subject 100 based on shape data regarding the shape of the subject's 100's head.

[0145] (10) The program causes the computer (server 3) to realize the function of inputting and outputting helmet information and shape data regarding the cranial shape correction helmet 7 between a doctor's terminal 2 used by a therapist treating the cranial shape of the subject 100, and a manufacturer's terminal 4 used by a manufacturer of the cranial shape correction helmet 7 to be worn on the head of the subject 100 to correct the cranial shape, based on shape data regarding the shape of the subject's 100's head photographed by the therapist.

[0146] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified as appropriate.

[0147] For example, the server 3 may not include at least any of the severity calculation unit 52, the treatment period estimation unit 55, the target head circumference calculation unit 56, and the slit width calculation unit 57. For example, if the server 3 does not include the treatment period estimation unit 55, the therapist may calculate the estimated treatment period required for the correction of the cranial shape of the subject 100 and input the calculated estimated treatment period to the server 3 via the doctor's terminal 2. This allows the subject 100 or a person related to the subject 100 to obtain the estimated treatment period from the server 3 using the subject's terminal 5, and information regarding the treatment period can be easily shared with the therapist. Also, for example, if the server 3 does not include the slit width calculation unit 57, the therapist may calculate a slit width d suitable for the subject 100 and input the calculated slit width d to the server 3 via the doctor's terminal 2. This allows the manufacturer of the cranial shape correction helmet 7 or the subject 100 or a person related to the subject 100 to obtain information regarding the slit width d from the server 3 via the manufacturer's terminal 4 or the subject's terminal 5.
