Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a diagnostic and treatment device and system. Background Technology

[0002] Radiation therapy is a treatment method for tumors that primarily uses high-energy rays to kill or control the growth of cancer cells, thereby treating the tumor. The radiation therapy process typically begins with imaging the patient to obtain information such as the tumor's location, size, and shape. The patient is then transferred to the treatment device, and based on the information obtained from the imaging, high-energy rays are directed at the patient to perform radiation therapy.

[0003] In related technologies, during patient examination using imaging devices, the patient is typically fixed on the imaging device's examination table, and marks are made on the patient's body surface. Subsequently, during radiotherapy for tumors using treatment devices, the patient needs to be positioned on the treatment table of the treatment device to ensure that the marks and laser positioning lines coincide, thereby ensuring that high-energy rays irradiate the tumor. However, positioning the patient based on the marks on the body surface and the laser positioning lines has poor accuracy, easily causing deviations in the position of high-energy ray irradiation, resulting in poor treatment outcomes. Utility Model Content

[0004] The purpose of this invention is to provide a diagnostic and treatment device and system that aims to solve the problem that poor patient positioning accuracy during radiotherapy can easily cause deviations in the position of high-energy radiation, resulting in poor treatment effects.

[0007] The diagnostic and treatment device in this application includes an imaging apparatus capable of capturing the patient's body features to obtain a three-dimensional contour surface of the patient's body. This allows for patient positioning based on more points on the three-dimensional contour surface, thereby improving positioning accuracy and, consequently, the positioning accuracy of high-energy radiation irradiation, thus enhancing treatment efficacy.

[0008] In some embodiments, the diagnostic device includes a plurality of imaging devices arranged at circumferential intervals along the through-hole.

The fixing portion is sleeved on the rotating member, and the connecting portion is connected to the fixing portion, with the connecting portion and the fixing portion arranged sequentially along the axial direction of the through hole. The connecting portion is located on one side of the rotating member along the axial direction of the through hole. At least one imaging device is fixed to the connecting portion.

[0012] In some embodiments, the imaging device includes a camera body and a lens. The lens is connected to the camera body, and the camera body can capture images through the lens. The lens is extendable and retractable along its optical axis.

[0013] In some embodiments, the angle between the optical axis of the lens and the axis of the through hole is an acute angle.

[0014] In some embodiments, the rotation axis of the rotating component is parallel to the axis of the through hole.

[0015] In some embodiments, the diagnostic device further includes a base, and a fixing sleeve is disposed on the base. The dimension of the base in the axial direction of the through hole is larger than the dimension of the fixing sleeve in the axial direction of the through hole.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that in practical applications, due to limitations in equipment precision or installation errors, achieving absolute parallelism or perpendicularity is difficult. The descriptions of "perpendicular," "parallel," or "in the same direction" in this application are not absolute limitations, but rather indicate that a vertical or parallel structural arrangement can be achieved within a preset error range, achieving the corresponding preset effect. This maximizes the technical effect of the defined features and makes the corresponding technical solution easy to implement, possessing high feasibility. For example, "perpendicular" includes absolute perpendicularity and near-perpendicularity, where the acceptable deviation range for near-perpendicularity can be, for example, within 5°. "Parallel" includes absolute parallelism and near-parallelism, where the acceptable deviation range for near-parallelism can also be, for example, within 5°. "In the same direction" includes absolute same direction and near-same direction, where the acceptable deviation range for near-same direction can also be, for example, within 5°.

[0033] In the description of the embodiments of this application, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0034] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a direct connection or an indirect connection through an intermediate medium, or a communication between the internal components of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] In the description of embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, article, or apparatus that includes that element.

[0036] In the description of the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this utility model should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0037] Radiation therapy is a treatment method for tumors that primarily uses high-energy rays to kill or control the growth of cancer cells, thereby treating the tumor. The radiation therapy process typically begins with imaging the patient to obtain information such as the tumor's location, size, and shape. The patient is then transferred to the treatment device, and based on the information obtained from the imaging, high-energy rays are directed at the patient to perform radiation therapy.

[0038] In traditional radiotherapy, during patient monitoring using an imaging device, the patient is typically fixed on the imaging bed, and laser lines are marked on the patient's skin. Then, during radiotherapy for the tumor, the technician positions the patient on the treatment bed based on the alignment of these marks and the laser positioning lines to ensure that high-energy rays are directed at the tumor. While the technician needs to observe the alignment of the laser positioning lines and the patient's skin markings to confirm correct positioning, this method of positioning is not very precise and can easily lead to deviations in the placement of high-energy rays, resulting in poor treatment outcomes.

[0039] Furthermore, when the treatment device is a ring-shaped roller accelerator, the patient typically needs to be positioned outside the device, and the treatment bed must then move a certain distance to transfer the patient to the center of the treatment. This reduces the precision of the treatment, resulting in poorer treatment outcomes.

[0040] Based on this, see Figure 1 , Figure 1 This is a schematic diagram of a diagnostic and treatment system 100 provided in this application embodiment, in the state of performing radiotherapy on a patient's chest and abdomen. This application embodiment provides a diagnostic and treatment system 100 to address the problem that poor patient positioning accuracy during radiotherapy can easily cause deviations in the position of high-energy radiation, leading to poor treatment effects and endangering healthy tissues surrounding the patient's target area.

[0041] Among them, see Figure 2 , Figure 2This is a schematic diagram of the structure of a diagnostic and treatment device 1 provided in an embodiment of this application. The diagnostic and treatment system 100 includes the diagnostic and treatment device 1, which includes a fixed sleeve 11 and a rotating member 12. The fixed sleeve 11 is sleeved on the rotating member 12, and the rotating member 12 is rotatable relative to the fixed sleeve 11. The rotating member 12 is provided with a through hole 121, and the rotation axis of the rotating member 12 is located within the through hole 121.

[0042] It should be noted that the rotation axis of the rotating component 12 can be set to be oblique to, parallel to or coincide with the axis of the through hole 121. The specific choice can be made according to the actual situation, and this application does not make any specific limitation.

[0043] For example, the axis of rotation of the rotating member 12 coincides with the axis of the through hole 121, meaning that the rotating member 12 can rotate about the axis of the through hole 121. This arrangement ensures that the position of the through hole 121 remains relatively fixed as the rotating member 12 rotates. This facilitates inserting a patient into the through hole 121 for examination or treatment.

[0044] In some embodiments, see Figure 3 , Figure 3 This is a schematic diagram of another diagnostic and treatment device 1 provided in an embodiment of this application. The diagnostic and treatment device 1 also includes an imaging device 13, wherein the imaging device 13 can be a camera that captures the shape and displacement of a target body, such as a body surface optical camera, a CCD camera, etc.

[0045] For example, such as Figure 3 As shown, along the radial direction of the through-hole 121, the imaging device 13 is disposed on the side of the fixed sleeve 11 near the rotating member 12. That is, the imaging device 13 is disposed inside the fixed sleeve 11, specifically on the side of the fixed sleeve 11 near the treatment area of ​​the diagnostic and treatment device 1. The treatment area is located within the through-hole 121, and the diagnostic and treatment device 1 is used to deliver a radiation beam to the treatment area for radiotherapy of the patient within the treatment area.

[0046] It is understood that the imaging device 13 can be connected to the fixed sleeve 11 to fix the imaging device 13 relative to the fixed sleeve 11; or the imaging device 13 can be connected to the rotating member 12 to rotate with the rotating member 12. The specific choice can be made according to the actual situation, and this application does not make specific limitations in this regard.

[0047] It should be noted that the imaging device 13 can capture the patient's body features within the through-hole 121 of the rotating member 12, thereby obtaining the three-dimensional contour surface of the patient's body. The patient's body features can be the patient's body surface morphology, such as the contours of the patient's head and chest / abdomen or feature points with distinctive shapes, or they can be markers on the patient's body surface; this application does not specifically limit this.

[0048] This embodiment of the application, by setting up the imaging device 13, can position the patient based on more points on the three-dimensional contour surface of the patient's body, thereby improving the positioning accuracy and the positional accuracy of high-energy ray irradiation, so as to improve the treatment effect.

[0049] In related technologies, the imaging device 13 is typically installed on the ceiling of a hospital radiotherapy room. However, to avoid obstructing the movement of operators and equipment, the imaging device 13 usually needs to be positioned far from the treatment isocenter. This results in a greater distance between the imaging device 13 and the patient during radiotherapy. This long-distance irradiation reduces the imaging device 13's sensitivity to the microscopic features of the patient's body surface. Furthermore, in the case of a ring-shaped roller accelerator, the roller can easily obstruct the imaging device 13, making it impossible to accurately and comprehensively observe the state of the patient's lesion at the treatment isocenter, thus reducing positioning accuracy. In addition, the ceiling of a hospital radiotherapy room typically houses many components, making the installation and subsequent maintenance of the imaging device 13 inconvenient. The installation and integration of the imaging device 13 is complex, time-consuming, and labor-intensive.

[0050] In this embodiment, the imaging device 13 is positioned inside the fixing sleeve 11, which shortens the distance between the imaging device 13 and the patient, enabling close-range observation of the patient. This arrangement results in clearer, more precise, and more recognizable images captured by the imaging device 13, facilitating accurate patient positioning at the treatment center and monitoring of the patient's location. Furthermore, the imaging device 13 can be integrated with the fixing sleeve 11, rotating component 12, etc., of the diagnostic and treatment equipment 1, achieving a high degree of integration. This reduces the hassle of later installation of the imaging device 13, improving the installation efficiency of the diagnostic and treatment equipment 1 and increasing on-site delivery efficiency.

[0051] This application embodiment does not specifically limit the number of imaging devices 13 in the diagnostic and treatment equipment 1. The diagnostic and treatment equipment 1 may include one or more imaging devices 13, which can be selected according to the actual situation.

[0052] For example, such as Figure 4 As shown, Figure 4 This is a front view of a diagnostic and treatment device 1 provided in an embodiment of this application. The diagnostic and treatment device 1 includes a plurality of imaging devices 13, which are arranged at circumferential intervals along a through-hole 121. This arrangement allows for observation of the patient from different perspectives through the multiple imaging devices 13, facilitating the identification of finer movements of body features.

[0053] In some embodiments, see Figure 5 , Figure 5 for Figure 3A cross-sectional view of the diagnostic and treatment device 1. At least one imaging device 13 is fixed relative to the fixing sleeve 11. It is understood that during radiotherapy, the imaging device 13, which is fixed relative to the fixing sleeve 11, can remain relatively fixed to the patient within the through-hole 121. Using this camera, the patient can be continuously observed in the same direction, allowing for more intuitive and detailed observation of whether the patient's position has changed, thus helping to improve the accuracy of observation.

[0054] For example, such as Figure 6 As shown, Figure 6 for Figure 1 The diagram shows the structure of the diagnostic and treatment system 100 from another perspective. The diagnostic and treatment device 1 includes three imaging devices 13, meaning there are three imaging devices 13 in the diagnostic and treatment device 1. The three imaging devices 13 are fixed relative to the fixing sleeve 11, and the visual isocenters of the three imaging devices 13 converge at the same point.

[0055] To facilitate observation of the patient, three imaging devices 13 can be positioned above the through-hole 121. For example, the three imaging devices 13 include one main-view camera 131 and two side-view cameras 132. Along the circumference of the through-hole 121, the main-view camera 131 is located between the two side-view cameras 132, and the main-view camera 131 is located in the center above the through-hole 121 (for example, the main-view camera 131 is located directly above the through-hole 121).

[0056] Among them, the main view camera 131 can monitor the positional changes of the body contour in the upper main view area of ​​the patient, while the two side view cameras 132 can more accurately monitor the subtle displacements of the patient's body on both sides, thus improving the observation accuracy.

[0057] In some embodiments, see Figure 5 The fixed sleeve 11 includes a fixed part 111 and a connecting part 112. The fixed part 111 is sleeved on the rotating part 12, and the connecting part 112 is connected to the fixed part 111. The connecting part 112 and the fixed part 111 are arranged sequentially along the axial direction of the through hole 121.

[0058] The connecting part 112 is located on one side of the rotating part 12 along the axial direction of the through hole 121, and at least one imaging device 13 is fixed to the connecting part 112.

[0059] For example, along the axial direction of the through hole 121, at least one imaging device 13 is disposed on the side of the rotating member 12 near the connecting portion 112 and is fixedly connected to the connecting portion 112 by a mounting bracket.

[0060] In other embodiments, the rotating member 12 includes a first sub-member and a second sub-member, which are spaced apart along the axial direction of the through hole 121, and the fixing part 111 is sleeved on the first sub-member and the second sub-member.

[0061] Based on this, at least one imaging device 13 is fixed to the fixing sleeve 11 through the gap between the first sub-component and the second sub-component.

[0062] For example, along the axial direction of the through hole 121, at least one imaging device 13 is disposed between the first sub-component and the second sub-component, and is fixedly connected to the fixing sleeve 11 by a mounting bracket.

[0063] In some embodiments, see Figure 7 , Figure 7 This is a schematic diagram of the structure of an imaging device 13 provided in an embodiment of this application. The imaging device 13 includes a camera body 133 and a lens 134. The lens 134 is connected to the camera body 133, and the camera body 133 can capture images through the lens 134.

[0064] The lens 134 can extend and retract along its optical axis, which allows for adjustment of the focal length, helps improve the imaging effect of the imaging device 13, and thus improves the accuracy of patient observation.

[0065] It should be noted that the imaging device 13 may contain one or more lenses 134, which can be selected according to the actual situation, and this application does not make a specific limitation in this regard. For example, the imaging device 13 may include one or two lenses 134.

[0066] In some embodiments, see Figure 5 The angle α between the optical axis of lens 134 and the axis of through hole 121 is an acute angle. For example, the optical axis of lens 134 is oblique to the axis of through hole 121.

[0067] The included angle α can be designed based on the axial dimensions of the fixing sleeve 11 in the through hole 121. For example, the larger the axial dimensions of the fixing sleeve 11 in the through hole 121, that is, the wider the fixing sleeve 11, the smaller the included angle α. This prevents the fixing sleeve 11 from obstructing the field of view of the imaging device 13, thereby reducing the blind spot.

[0068] It is understood that the optical axis of lens 134 can also be set to be perpendicular to the axis of through hole 121, and this application does not make specific limitations on this.

[0069] In some embodiments, see Figure 5 The diagnostic and treatment device 1 also includes a base 14, on which a fixing sleeve 11 is disposed. The base 14 provides support for the fixing sleeve 11, and the diagnostic and treatment device 1 can be stably installed on the floor of the machine room via the base 14.

[0070] The dimension of the base 14 in the axial direction of the through hole 121 can be set to be larger than the dimension of the fixing sleeve 11 in the axial direction of the through hole 121. This can improve the reliability of the installation of the diagnostic and treatment equipment 1 and reduce the probability of the diagnostic and treatment equipment 1 shaking.

[0071] In some embodiments, the diagnostic device 1 further includes an industrial design, with the rotating component 12 and the fixed sleeve 11 at least partially encased inside the industrial design, and the imaging device 13 encased inside the industrial design.

[0072] The industrial design includes a clearance opening, and the imaging device 13 is located at the clearance opening. The imaging device 13 can capture the patient's body features through the clearance opening.

[0073] For example, the lens 134 of the imaging device 13 can extend from the inside of the industrial design through a clearance opening, which can reduce the space occupied by the imaging device 13 in the diagnostic and treatment equipment 1 and help improve the acquisition effect of the imaging device 13.

[0074] In some embodiments, see Figure 6 The diagnostic and treatment device 1 also includes a drive assembly 15, which is used to drive the rotating part 12 to rotate relative to the fixed sleeve 11.

[0075] For example, the drive assembly 15 includes a drive motor 151, a transmission assembly 152, and a drive gear 153. The output shaft of the drive motor 151 is connected to the drive gear 153 through the transmission assembly 152, and the drive gear 153 is meshed with the rotating member 12. The transmission assembly 152 may include at least one of a gear and a worm gear.

[0076] Alternatively, the drive gear 153 can be directly connected to the output shaft of the drive motor 151, in which case there is no need to set up the transmission assembly 152.

[0077] It should be noted that the drive motor 151 can be fixed on the base 14 or the fixing sleeve 11, and the specific choice can be made according to the actual situation.

[0078] In some embodiments, see Figure 6 The diagnostic and treatment system 100 also includes a treatment bed 2, which includes a bed board 21 and a drive device connected to each other. The bed board 21 is used to support the patient, and the drive device is used to send the bed board 21 into the through hole 121 of the rotating member 12.

[0079] Understandably, during radiotherapy, the drive device can send the bed board 21 into the through hole 121 of the rotating component 12, so that the patient lying on the bed board 21 can receive examination and treatment from the diagnostic and treatment equipment 1 within the through hole 121.

[0080] This application does not specifically limit the configuration of the drive device; for example, the drive device can be a robotic arm.

[0081] In some embodiments, see Figure 1 and Figure 8 , Figure 8 This is a schematic diagram of a diagnostic and treatment system 100 provided in an embodiment of this application, in a state of performing radiotherapy on a patient's head. The diagnostic and treatment system 100 is capable of performing radiotherapy on a patient. For example, the diagnostic and treatment system 100 can be used to perform radiotherapy on at least one of the patient's head and chest / abdomen.

[0082] During radiotherapy to the patient's head, the drive device can drive the bed board 21 to move so that the patient's head is moved into the irradiation area of ​​the imaging device 13; during radiotherapy to the patient's chest and abdomen, the drive device can drive the bed board 21 to move so that the patient's chest and abdomen are moved into the irradiation area of ​​the imaging device 13.

[0083] It is understood that the diagnostic and treatment system 100 can also be used to perform radiotherapy on other parts of the patient's body, and this application does not specifically limit this.

[0084] In some embodiments, the diagnostic system 100 may further include an imaging control and processing device, a host computer, and a slave computer.

[0085] The imaging control and processing equipment is used to receive images acquired by the imaging device 13, record the corresponding motion coordinates of the treatment bed 2, analyze and process the images, compare the acquired images with the target treatment position, and output the corresponding offset. The processing may include noise reduction and reconstruction.

[0086] The imaging control and processing device may run a computer system, which includes a processor. The processor is used to receive images acquired by the imaging device 13, analyze and process the images, and output the corresponding offset.

[0087] In some embodiments, the imaging control processing device is a computer device with a graphical user interface (GUI), which includes one or more processors, memory, and one or more application programs. For example, the imaging control processing device may include an imaging system application program, which is executed by the processor of the imaging control processing device to reconstruct multiple sub-projection images from the projection images corresponding to each group of focal light sources, thereby obtaining a three-dimensional image of the target soft tissue.

[0088] In the embodiments of this application, the entity of the imaging control and processing device can be a terminal or a server, and the embodiments of this application do not limit it in this way.

[0089] Optionally, the aforementioned terminal may be at least one of the following devices: smartphone, smartwatch, desktop computer, laptop, virtual reality terminal, augmented reality terminal, wireless terminal, and laptop computer.

[0090] Optionally, the aforementioned server can be an independent physical server, a server cluster composed of multiple physical servers, a distributed file system, or at least one of the following cloud servers providing basic cloud computing services: cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks, and big data or artificial intelligence platforms. This application embodiment does not limit this. In some embodiments, the number of the aforementioned servers can be more or less, and this application embodiment does not limit this. Of course, the server can also include other functions to provide more comprehensive and diversified services. The host computer is used to receive the offset output by the imaging control processing device and determine whether to continue treatment or stop treatment and reposition the patient based on whether the offset exceeds a threshold. When treatment needs to be stopped and repositioned, the host computer can issue a repositioning command.

[0091] The lower-level computer is used to receive positioning instructions and, based on these instructions, control the treatment head to stop emitting the beam and control the movement of the treatment bed 2.

[0092] In the radiotherapy procedure, based on the diagnostic and treatment system 100 in this embodiment, the following steps can be used to achieve automatic patient positioning:

[0093] ① The patient is located on a simulated positioning system, and the treatment target area is marked. The marking method can be either traditional surface marking or data acquisition and marking using the imaging device 13.

[0094] ② During the initial treatment, the imaging device 13 acquires images and sends the image information to the imaging control and processing device. The imaging control and processing device receives the image information, reconstructs and analyzes the image, and outputs an offset value to the host computer. The host computer receives the offset value and determines whether the current position matches the target treatment position based on whether the offset value exceeds a threshold. If yes, the imaging device 13 acquires the patient's body features at the treatment position and records the motion coordinates of the treatment bed 2 at this time. If no, the host computer sends a positioning command, and the lower computer controls the treatment head to stop beam delivery and controls the movement of the treatment bed 2 based on the positioning command. The body features acquired by the imaging device 13 at the treatment position represent the position of the patient's target area at the treatment isocenter.

[0095] ③ During subsequent treatment sessions, the treatment bed 2 moves to the position corresponding to the coordinate value of the treatment bed 2 recorded by the imaging control processing device during the previous treatment.

[0096] ④ After the patient on the treatment bed enters the field of view of the imaging device 13, the imaging device 13 acquires an image and sends the image information to the imaging control and processing device. After receiving the image information, the imaging control and processing device reconstructs the image and compares the current position with the previous treatment position, outputs the corresponding offset and sends it to the host computer. The host computer receives the offset and determines whether the current position is the target treatment position based on whether the offset exceeds the threshold. If yes, the imaging device 13 acquires the patient's body features at the treatment position and records the motion coordinates of the treatment bed 2 at this time. If no, the host computer sends a positioning command, and the slave computer controls the treatment head to stop beam output and controls the treatment bed 2 to move based on the positioning command.

[0097] In addition, during patient treatment, the imaging device 13 can acquire images in real time and send the image information to the imaging control and processing device. After receiving the image information, the imaging control and processing device reconstructs and analyzes the image, and outputs the offset to the host computer. The host computer receives the offset and determines whether to continue treatment or stop treatment and reposition the patient based on whether the offset exceeds a threshold. When it is necessary to stop treatment and reposition the patient, the host computer sends a repositioning command, and the slave computer controls the treatment head to stop beam output and controls the movement of the treatment bed 2 based on the repositioning command.

[0098] In addition, the imaging device 13 can also collect and monitor the characteristics of the patient's body surface during the respiratory process during treatment to determine the movement of the patient's lesion location, so as to monitor the body surface characteristics during the patient's periodic movement process, thereby providing information for technologies such as respiratory gating and DIBH treatment.
