Technical Field

[0001] This invention relates to a portable processing device, processing method, and computer program. Background Technology

[0002] In medical examinations, images obtained by directly photographing the object being examined or by visualizing measurement results obtained using electromagnetic waves are used for diagnosis. In particular, techniques for obtaining images by moving imaging elements within the organ are widely used in the examination of luminal organs.

[0003] To ensure the safe and reliable performance of medical procedures such as percutaneous coronary intervention (PCI), imaging diagnosis of vascular organs, especially blood vessels, is essential. Therefore, in addition to angiography, which uses contrast agents to take images externally, intravascular imaging techniques such as catheter-based IVUS (Intravascular Ultrasound), OCT (Optical Coherence Tomography), and OFDI (Optical Frequency Domain Imaging) have become widely used.

[0004] Patent document 1 discloses an ultrasonic probe that is wirelessly audible and wirelessly rechargeable, designed to solve the problem of cumbersome cable laying. In imaging technologies using conduits, such as OVUS and OCT, portability can also be achieved through wireless image transmission. Existing technical documents Patent documents

[0022] Hereinafter, specific examples of the image diagnostic apparatus, image diagnostic method, and computer program according to embodiments of the present invention will be described with reference to the accompanying drawings.

[0023] (First Embodiment) Figure 1 This is a schematic diagram of an image diagnostic system 200 including the processing apparatus 1 of the first embodiment. The image diagnostic system 200 is configured to include a processing apparatus 1, a conduit 2, a light source device 3, and an information processing device 4. The processing apparatus 1, conduit 2, light source device 3, and information processing device 4 can be used as follows when not in use: Figure 1 The diagram shows the parts separated.

[0024] The catheter 2 is a flexible medical tube inserted into the lumen of a diagnostic subject's organ. The catheter 2, referred to as an imaging catheter, has a shaft through which an imaging device 21 is connected at its end. The imaging device 21 within the catheter 2 and the shaft are driven by a processing device 1 connected via a connector 22 at the base end to rotate circumferentially.

[0025] The imaging device 21 of the catheter 2 is a dual-mode device comprising a transmitter and a receiver for waves (ultrasound, light) of different wavelengths. The imaging device 21 includes circuitry for IVUS and OCT. The dual-mode is not limited to a combination of IVUS and OCT; it can also utilize near-infrared spectroscopy, etc. The imaging device 21 is not limited to dual-mode; it can also utilize imaging techniques using only IVUS, only OCT, or only near-infrared spectroscopy.

[0026] The signal obtained by the imaging device 21 of the catheter 2 is output to the base end of the catheter 2 via a signal line arranged in the shaft. The processing device 1 connected to the catheter 2 operates the imaging device 21 of the catheter 2, processes the signal obtained by the imaging device 21, and sends it to the information processing device 4.

[0027] The light source device 3 is a device equipped with an optical system for obtaining OCT images by utilizing the interference-prone nature of light. The light source device 3 is not strictly necessary, but in the first embodiment, since a dual-mode device combining IVUS and OCT is used as the imaging device 21, a structure with the light source device 3 connected to it will be described. The light source device 3 is disposed under the bed of a patient using the image diagnostic system 200. The light source device 3 receives power from the power system and, via the processing device 1, outputs light from the light source to the imaging device 21 of the catheter 2.

[0028] The information processing device 4 is a device that, based on signals obtained by the imaging device 21 of the processing device 1, creates a tomographic image of the inside of a lumen organ to which the catheter 2 is inserted, and outputs information obtained by processing the created tomographic image. The information processing device 4 is, for example, a medical device such as an intravascular imaging diagnostic device, an angiography device, an external monitor, and an electrocardiograph. The information processing device 4 outputs the processed information to a built-in display unit 45 or to an externally connected display unit 45. The information processing device 4 can be a smartphone or tablet terminal, a laptop computer (PC), or a desktop PC, and functions as a medical device such as an intravascular imaging diagnostic device based on software programs, depending on its intended use.

[0029] In the image diagnostic system 200 disclosed herein, the processing device 1 is as follows: Figure 1 As shown, the display unit 45 and information processing device 4 are not integrated with the area where medical treatment is performed. The processing device 1 can be detachably configured so that it can be taken out from a designated location and used in the area where the catheter 2 is used for medical treatment. When performing medical treatment using the catheter 2, the operator, such as a doctor or examination technician, connects the catheter 2 and the light source device 3 to the processing device 1, and then connects it to the information processing device 4 wirelessly to use the processing device 1.

[0030] Processing device 1 as follows Figure 1 As shown, the housing 10 has an elongated, generally rectangular shape. The processing device 1 is preferably sized to be operable with one hand. The processing device 1 has a built-in battery, which is used as a power source for operation. Thus, the processing device 1 can be attached to and detached from the catheter 2 and the light source device 3, and data input and output with the information processing device 4 can be realized wirelessly, realizing a portable image diagnostic device for the catheter 2.

[0031] While the portability of the processing device 1 facilitates operation, it is important to ensure that the power supply from its built-in battery is not interrupted during medical procedures. Therefore, in the processing device 1 of the first embodiment and the embodiments described below, the remaining power of the processing device 1, displayed on the display unit 14 exposed from the housing 10 or the display unit 45 of the information processing device 4, is used in medical procedure units to display the number of times the processing device 1 can be used with its built-in battery. Here, the number of medical procedure units indicates how many times the power supply of the processing device 1 can be continuously turned on during a single medical procedure, regardless of the number of scans performed using the imaging device 21 after catheter 2 insertion. In a single medical procedure, for example, multiple scans are usually performed to observe the condition of the target vessel wall before stent or balloon placement, and to confirm the condition of the vessel wall after stent or balloon placement. The processing device 1 expresses its remaining power in units of the number of times it can be used uninterruptedly during the period from catheter 2 insertion to the completion of the medical procedure while the power supply is on.

[0032] The structure of the processing device 1 and the handling of the remaining battery capacity will be described below. Figure 2 This is a block diagram showing the structure of the processing device 1 according to the first embodiment. The processing device 1 includes a housing 10, a processing unit 11, a storage unit 12, a wireless communication unit 13, a display unit 14, an operation unit 15, a power supply unit 16, and an image processing circuit 17.

[0033] 10 shells Figure 1 As shown, it has a slender, generally rectangular shape. The housing 10 internally houses a processing unit 11, a storage unit 12, a wireless communication unit 13, a display unit 14, an operation unit 15, a power supply unit 16, and an image processing circuit 17. The housing 10 exposes a portion of each of the display unit 14, the operation unit 15, the power supply unit 16, and the image processing circuit 17.

[0034] The processing unit 11 includes processors such as a CPU (Central Processing Unit), an MPU (Micro-Processing Unit), and a GPU (Graphics Processing Unit). The processing unit 11 also includes memories such as RAM (Random Access Memory) and ROM (Read Only Memory). The processors read data from the memories, temporarily store the processing results in the memories, and then execute the processing. Based on the control program P1 stored in the storage unit 12 and the data, the processing unit 11 controls each structural unit to execute the process of outputting remaining power.

[0035] Storage unit 12 is a non-volatile memory such as flash memory or SSD. Storage unit 12 stores the data referenced by processing unit 11, such as the historical record of the amount of electricity used in a single medical procedure as described later, as a power usage history. Storage unit 12 stores control program P1.

[0036] The control program P1 stored in the storage unit 12 may also be a program that the processing unit 11 reads the control program P9 stored in the non-temporary storage medium 9 that can be read by a computer and stores the control program P9 in the storage unit 12.

[0037] The wireless communication unit 13 is a short-range wireless communication module, such as Bluetooth (registered trademark). The processing unit 11 can use the wireless communication unit 13 to send data to the information processing device 4. The processing unit 11 can also use the wireless communication unit 13 to receive data from the information processing device 4.

[0038] Display unit 14 is a liquid crystal display, an organic EL (electroluminescence) display, or the like. Display unit 14 can also be an LED lamp or a segmented display. Processing unit 11 outputs information related to the remaining power of battery 161 to display unit 14 based on control program P1. In addition to display unit 14, processing unit 11 can also use a sound output unit including a speaker to output information with sound such as beeps.

[0039] The operation unit 15 is a physical UI that enables input and output between the operation unit 11 and the processing unit 11. The operation unit 15 may be a physical button, for example. The operation unit 15 may also be a touch panel built into the display unit 14. The operation unit 15 may also use a sound input unit including a microphone. The operation unit 15 includes a power button and a scan button, which is pressed to start processing by the image processing circuit 17. In addition, the operation unit 15 may also include a record button for recording signal data acquired by the image processing circuit 17. The operation unit 15 identifies which button is selected and pressed and notifies the processing unit 11.

[0040] The power supply unit 16 includes a battery 161 and a battery management unit (BMU) 162. The battery 161 is a rechargeable secondary battery. For example, the battery 161 is a lithium-ion battery. When the power supply unit 16 is activated using the power button included in the operation unit 15, power is supplied from the battery 161 to each structural component of the processing device 1. The battery 161 supplies power to components driven by the conduit 2 connected at the first connection 174, such as the imaging device 21. The battery 161 may also be replaceable. The BMU 162 can output data on the output voltage, current value, and remaining power of the battery 161.

[0041] The power supply unit 16 can accept external power supply via a USB (Universal Serial Bus) cable to charge the battery 161. The power supply unit 16 may include a receiving coil for wireless charging.

[0042] The image processing circuit 17 performs motion control of the conduit 2 of the processing device 1 and processes the signals obtained from the conduit 2. The image processing circuit 17 includes an MDU (Motor Drive Unit) 171, an IVUS circuit 172, an OCT circuit 173, a first connection part 174, and a second connection part 175.

[0043] MDU171 is the drive device for catheter 2. MDU171 is driven according to the control signal from processing unit 11. MDU171 drives the internal motor for catheter 2 connected via first connection part 174 according to the operation of operation part 15 by operator such as doctor or examination technician, thereby controlling the rotation of catheter 2 and the operation of imaging device 21.

[0044] IVUS circuit 172 drives the ultrasonic transducer of imaging device 21 using the IVUS method, acquiring signals from the ultrasonic probe for each radial scan. IVUS circuit 172 outputs the signal for each scan by adding identification data for identifying which data point it is, for example, every 360 degrees.

[0045] The OCT circuit 173 outputs light from the light source device 3 to drive the near-infrared light-emitting part of the imaging device 21. Each radial scan acquires a signal from the near-infrared sensor. The OCT circuit 173 adds identification data to the signal of each scan, for example, every 360 degrees, to identify which data point it is, and outputs it.

[0046] When the image processing circuit 17 starts processing, the processing unit 11 sends the scan signals of IVUS and OCT obtained from IVUS circuit 172 and OCT circuit 173, along with the identification data, from the wireless communication unit 13 to the information processing device 4.

[0047] The connector 22 of the conduit 2 is detachably connected to the first connection portion 174. The first connection portion 174 has a rotary drive mechanism to drive the rotation of the MDU 171 into the shaft within the conduit 2. The second connection portion 175 is detachably connected to the light source device 3. The second connection portion 175 is connected to an optical fiber disposed in the image processing circuit 17. The second connection portion 175 outputs light from the connected light source device 3 to the OCT device within the conduit 2 via the optical fiber and the first connection portion 174.

[0048] Figure 3This is a block diagram showing the structure of the information processing device 4. The information processing device 4 includes a processing unit 40, a storage unit 41, a wireless communication unit 43, a display unit 45, and an operation unit 46. The display unit 45 and / or the operation unit 46 may also be external and exchange signals with the processing unit 40 via an input / output interface.

[0049] The processing unit 40 includes one or more processors such as CPU, MPU, GPU, GPGPU (General-purpose computing on graphics processing units), or TPU (Tensor Processing Unit). The processing unit 40 has built-in non-temporary storage media such as RAM, which stores the data generated during processing in the non-temporary storage media, and performs operations based on the computer program P4 stored in the storage unit 41.

[0050] Storage unit 41 is a non-volatile storage medium such as a hard disk or flash memory. Storage unit 41 stores data read from processing unit 40.

[0051] The wireless communication unit 43 is a short-range wireless communication device. The wireless communication unit 43 can be any communication device that achieves wireless communication with the wireless communication unit 13 of the processing device 1 via a corresponding communication protocol. The processing unit 40 receives data from the processing device 1 using the wireless communication unit 43.

[0052] The display unit 45 uses a liquid crystal display panel, an organic EL display panel, or the like. The display unit 45 basically displays medical images created by the processing unit 40 and information related to those medical images. As described later, the display unit 45 can output information related to the remaining power of the processing device 1, which is output by the processing unit 40.

[0053] The operation unit 46 is an input interface for accepting operations on the information processing device 4. The operation unit 46 can be a keyboard and mouse, or a touch panel, soft keys, and hard keys built into the display unit 45. The operation unit 46 can also accept voice-based input. In this case, the operation unit 46 uses a microphone and a voice recognition engine.

[0054] In the image diagnostic system 200 configured as described above, for each IVUS and OCT, the processing unit 1 sends the signals from each scan obtained by the imaging device 21, along with identification data, to the information processing unit 4. In the information processing unit 4, the processing unit 40 generates a rectangular image in which the signals from each scan are radially aligned and arranged in a rectangular pattern based on the identification data, and a tomographic image obtained by polar coordinate transformation of this rectangular image, and displays it on the display unit 45. The processing unit 40 performs image processing on the tomographic image and displays the processing results on the display unit 45.

[0055] In the image diagnostic system 200, in order to perform the medical treatment of the catheter 2 without interruption in the portable processing device 1, the processing unit 11 displays the remaining power in an easy-to-understand manner on the display unit 14 or the display unit 45 based on the control program P1. The process of displaying the remaining power will now be explained with reference to the flowchart and display examples.

[0056] Figure 4 This is a flowchart illustrating an example of the processing sequence executed by the processing device 1. During its startup period, the processing unit 11 performs the following processing based on the operations received from the operator by the operation unit 15.

[0057] When the processing unit 11 is started in the power-on state by pressing the power button (step S101), it obtains the remaining battery power at startup from the BMU162 of the power supply unit 16 (step S102). The processing unit 11 starts measuring time (step S103), and starts or continues the processing performed by the image processing circuit 17 by pressing the scan button (step S104).

[0058] The processing unit 11 determines whether the scan has ended or the power button has been pressed again, and then shuts down the device (step S105). If it is determined that the power button has not been pressed (S105: No), the processing unit 11 returns the processing to step S104 and continues the processing performed by the image processing circuit 17.

[0059] If it is determined that the power button has been pressed again and the device is turned off (S105: Yes), the processing unit 11 ends the time measurement (step S106) and obtains the remaining battery level before the power-off from the BMU162 of the power supply unit 16 (step S107).

[0060] The processing unit 11 calculates the difference in battery capacity from startup to shutdown and the elapsed time from startup to shutdown (step S108), and stores this as a power usage history in the storage unit 12 (step S109). In step S108, if the processing unit 11 obtains the battery capacity as the charging rate from the BMU162, it can calculate the charging rate by multiplying it by the stored full charge capacity, or it can calculate it directly proportionally. In step S109, the processing unit 11 can also overwrite old historical records with new historical records, storing at least a predetermined number of records.

[0061] Based on the remaining battery power obtained in step S107 and the power usage history stored in the storage unit 12, the processing unit 11 calculates the number of medical treatments that can be performed using the remaining battery power (step S110).

[0062] In step S110, the processing unit 11, for example, sets the difference in battery remaining capacity from startup to shutdown during previous use as the usage power, and calculates the quotient obtained by dividing the battery remaining capacity at the execution time of step S110 by the usage power, using this quotient as the number of medical procedures that can be performed. In step S110, the processing unit 11 may also calculate the average of previous usage power (the difference in battery remaining capacity from startup to shutdown), and set this average as the usage power, using it as the divisor when dividing the battery remaining capacity. The processing unit 11 can calculate not only the average of previous usage power, but also the median or mode, and use these as the usage power.

[0063] In step S110, the processing unit 11 may, after retaining a predetermined number or more historical electricity usage records, pre-store the average value of the predetermined number of electricity usage records as the electricity usage in the storage unit 12, and then use it as the electricity usage without further calculation. In this case, the processing unit 11 may use not only the average value, but also statistical values ​​such as the median or mode. Alternatively, the processing unit 11 may pre-store the average, median, or mode of the electricity usage from the previous electricity usage records (after removing outliers and / or exceptions) as the electricity usage in the storage unit 12 for reference.

[0064] In step S110, the processing unit 11 may also define the elapsed time from startup to shutdown during previous use as one usage time, and calculate the quotient obtained by dividing the remaining battery time at the execution time of step S110 by one usage time, as the number of medical treatments that can be performed. The usable time based on the remaining battery time can be a standard value or calculated based on previous power usage history. For example, the processing unit 11 can calculate the usable time corresponding to the remaining battery time based on the relationship between the power consumption of each usage in the power usage history and the elapsed time from startup to shutdown (usage time).

[0065] The processing unit 11 displays the calculated number of medical treatments on the display unit 14 (step S111), and ends the processing to a power-off state. In step S111, if the calculated number of medical treatments is less than a predetermined number, the processing unit 11 may output a beeping sound from the speaker provided with the processing device 1 and display a message on the display unit 14 indicating that the remaining number of treatments is low.

[0066] exist Figure 4 In the processing sequence shown in the flowchart, the processing unit 11 calculates the amount of electricity used from the time the power is turned on by pressing the power button until the power is turned off. However, the present invention is not limited to this, and the processing device 1 may also calculate the amount of electricity used from the time the scan button is initially pressed until the device is turned off as the amount of electricity used in one cycle.

[0067] Figure 5 This is a flowchart illustrating another example of the processing sequence executed by the processing device 1. When the processing unit 11 is started in the power-on state by pressing the power button (step S201), it obtains the remaining battery power at startup from the BMU162 of the power supply unit 16 (step S202).

[0068] Processing unit 11 reads the power usage history stored in storage unit 12 (step S203) and determines the power consumption for one use based on the read power usage history (step S204). In step S204, processing unit 11 can determine the power consumption by the difference in battery remaining capacity from startup to shutdown in the immediate period of use, or by calculating the average (median or mode) of the power consumption. In step S204, processing unit 11 can also determine the power consumption for one use by calculating the average (median or mode) after removing outliers and / or irregularities from previous power consumption records in the power usage history. In step S204, processing unit 11 can also determine the power consumption for one use by the value that has been stored in storage unit 12 after a predetermined number of uses.

[0069] Based on the remaining battery power obtained in step S202 and the power consumption determined in step S204, the processing unit 11 calculates the number of medical procedures that can be performed in units of the number of medical procedures that can be performed using the catheter 2 (step S205).

[0070] The processing unit 11 displays the calculated number of medical procedures that can be performed on the display unit 14 (step S206), and ends the display process of the number of medical procedures that can be performed. The processing unit 11 enters a standby state, which can be turned off by pressing the power button, or the processing performed by the image processing circuit 17 can be started later by pressing the scan button.

Figure 6 The display content shown on the display unit 14 indicates the content displayed on the screen. The processing unit 11... Figure 4 Step S111 in the flowchart or Figure 5 Step S206 in the flowchart, to Figure 6 The shape shown indicates a margin. In Figure 6 In the example, the display unit 14 shows a metering unit 141 for indicating the percentage of remaining battery power and a value 142 for indicating the number of medical procedures that can be performed, "3". While the remaining battery power displayed by the metering unit 141 can be implemented using conventional portable electronic devices, it is unclear whether this remaining power can be used for a single medical procedure using the processing device 1. However, as... Figure 6 As shown, by calculating and displaying the number of medical treatments that can be performed, operators can easily manage the remaining power.

[0072] Figure 6 The metering unit 141 shown is not essential, but by displaying not only the numerical value 142 indicating the number of medical procedures that can be performed, but also... Figure 6 The metering unit 141 is also displayed, allowing the operator to visually monitor the correspondence between the number of medical treatments that can be performed and the remaining battery level.

[0073] (Second Implementation) In the second embodiment, the processing unit 11 of the processing device 1 calculates the number of medical procedures that can be performed as a numerical range. The structure of the image diagnostic system 200 of the second embodiment is the same as that of the image diagnostic system 200 of the first embodiment, except for the detailed processing described below. Therefore, the common structural elements of the image diagnostic system 200 of the second embodiment are labeled with the same reference numerals as in the first embodiment, and detailed descriptions are omitted.

[0074] Figure 7 It is a bar chart representing the historical records of electricity usage. Figure 7 The horizontal axis represents the number of times, and the vertical axis represents the amount of electricity used. Figure 7 The height of the bars in the bar chart represents the electrical energy used in each medical procedure (from startup to shutdown). The vertical axis on the right, along with the electrical energy used, represents the time required to complete one medical procedure for reference. Figure 7 As shown, the power consumption per medical procedure is uneven. For example, comparing the power consumption of the first medical procedure with that of the second and third medical procedures, the power consumption of the first medical procedure is about 20% less than that of the second and third procedures. The power consumption of the fourth medical procedure is about 20% more than that of the second and third procedures, and the power consumption of the fifth medical procedure is about 10% more than that of the second and third procedures. Because of this unevenness, in the second embodiment, the processing unit 11 does not represent the number of medical procedures that can be performed using the processing device 1 as a natural number obtained by rounding down the decimal part, but rather as a decimal that takes into account the unevenness.

[0075] In the second embodiment, each time it is used, the processing unit 11 of the processing device 1 functions as in the first embodiment. Figure 4 As shown in the flowchart, the power consumption from startup to shutdown is stored as a power usage history.

[0076] Figure 8 This is a flowchart illustrating an example of the order in which the number of medical procedures that can be performed by the processing device 1 of the second embodiment can be calculated. When the processing unit 11 is started in a power-on state by pressing the power button (step S301), it obtains the remaining battery power at startup from the BMU162 of the power supply unit 16 (step S302).

[0077] The processing unit 11 reads the power usage history stored in the storage unit 12 (step S303), removes outliers and / or outliers from the read power usage history (step S304), and determines the range of power consumption for one use (step S305). In step S305, the processing unit 11 determines, for example, the range of power usage history after removing outliers and / or outliers to be 320 [mAh] to 440 [mAh].

[0078] By using the process of removing outliers and / or isolated values ​​in step S304, the power consumption stored even when the device is in a power-on state after a test startup can be removed from the calculation of statistical values ​​such as average values, thereby improving accuracy.

[0079] Based on the remaining battery capacity obtained in step S302 and the range of power consumption determined in step S305, the processing unit 11 calculates the range of the number of medical treatments that can be performed in units of the number of medical treatments that can be performed by the processing device 1 (step S306). In step S306, for example, if the remaining battery capacity is 1200 mAh, which is 48% of the full charge capacity of 2500 mAh (standard value or estimated value), and the range of power consumption for one use is set to 320 mAh to 440 mAh, the processing unit 11 calculates that the range of the number of medical treatments that can be performed is 2.7 to 3.8 times.

[0080] The processing unit 11 displays the calculated range of possible medical procedures on the display unit 14 (step S307), and ends the display process for the number of possible medical procedures. The processing unit 11 enters a standby state, which can be turned off by pressing the power button again, or the processing performed by the image processing circuit 17 can be started later by pressing the scan button.

[0081] Figure 9 This is a diagram showing the remaining power in the processing device 1 of the second embodiment. Figure 9 Compared with the first embodiment Figure 6 Similarly, the display content of the display unit 14 is displayed. The processing unit 11 executes... Figure 4 In the case of the process shown in the flowchart, in the process of step S111, Figure 9 The shape shown indicates the margin, after execution Figure 8 In the case of the process shown in the flowchart, in the process of step S307, Figure 9 The shape shown indicates a margin. In Figure 9 In this context, the numerical value 142, representing the number of medical treatments that can be performed, is expressed as a range including decimals. For example... Figure 9 As shown, in the second embodiment, the value 142 of the number of medical procedures that can be performed is expressed as a numerical range. This makes it easier for the operator to intuitively grasp the remaining power. Furthermore, by intentionally displaying unevenness, an increase in the reliability of the displayed number of medical procedures that can be performed can be expected.

[0082] (Third implementation) The processing device 1 in the third embodiment has the function of calculating the number of medical procedures that can be performed with higher accuracy using the remaining battery power. The structure of the image diagnostic system 200 in the third embodiment is the same as that of the image diagnostic system 200 in the first embodiment, except for the structure and processing described below. Therefore, for structures in the image diagnostic system 200 of the third embodiment that are common to those in the first embodiment, the same reference numerals as in the first embodiment are used, and detailed descriptions are omitted.

[0083] Figure 10 This is a block diagram showing the structure of the processing device 1 in the third embodiment. In the third embodiment, the processing device 1 further includes a temperature sensor 18. The temperature sensor 18 is housed inside the housing 10 and measures the temperature inside the device. The temperature sensor 18 outputs the measured temperature to the processing unit 11. The processing unit 11 can store the measured temperature along with the electricity usage history stored in the storage unit 12 (step S109).

[0084] In the third embodiment, the processing unit 11 has the function of estimating the aging state of the battery 161. When the remaining power of the battery 161 is close to zero and it is continuously charged to a full charge, the processing unit 11 estimates the full charge capacity based on the accumulation of current detected by the BMU 162, and stores it in the storage unit 12 in correspondence with the time information obtained from the built-in timer or the wireless communication unit 13. The processing unit 11 can estimate the aging state based on the progression of the full charge capacity stored in the storage unit 12. The aging state estimation function can also be implemented using the BMU 162 instead of the processing unit 11. In this case, the processing unit 11 can obtain the aging state from the BMU 162.

[0085] The charge level of battery 161 varies with temperature and aging status. Therefore, the processing unit 11 of the processing device 1 in the third embodiment corrects the calculated number of medical treatments that can be performed based on the temperature data obtained from the temperature sensor 18 and the aging status of battery 161.

[0086] In the third embodiment, the processing unit 11 of the processing device 1, each time it is used, is as in the first embodiment. Figure 4 As shown in the flowchart, the electricity used from startup to shutdown is stored as a power usage history. When storing electricity, it is also possible to store the electricity used at a specified temperature (e.g., 25°C).

[0087] Figure 11This is a flowchart illustrating an example of the order in which the number of medical procedures that can be performed by the processing device 1 of the third embodiment can be calculated. When the processing unit 11 is started in the power-on state by pressing the power button (step S401), it obtains the remaining battery power at startup from the BMU162 of the power supply unit 16 (step S402).

[0088] The processing unit 11 reads the power usage history stored in the storage unit 12 (step S403), and determines the amount of electricity used per cycle based on a predetermined number of consecutive usage history records in the read power usage history records (step S404). In step S404, when the amount of electricity used changes accordingly with the aging of the battery 161, the processing unit 11 can calculate the number of medical treatments that can be performed in accordance with the aging by using the amount of electricity used in the consecutive usage history records.

[0089] The processing unit 11 corrects the remaining battery level obtained in step S402 (step S405) based on the acquired or estimated aging state and the temperature obtained from the temperature sensor 18. In step S405, the processing unit 11 may perform the correction based on the difference between the temperature data included in the power usage history read in step S403 and the temperature data obtained from the temperature sensor 18 at the time point in step S405. Alternatively, instead of the processing in step S405, the processing in step S404 may perform processing consistent with the power usage at the same temperature (e.g., room temperature 25°C).

[0090] Based on the corrected battery balance in step S405 and the single-use power determined in step S404, the processing unit 11 calculates the number of medical treatments that can be performed in units of the number of medical treatments that can be performed by the processing device 1 (step S406).

[0091] The processing unit 11 displays the calculated number of medical treatments that can be performed, the temperature, and the aging status on the display unit 14 (step S407), and ends the display processing of the number of medical treatments that can be performed.

[0092] In the first embodiment Figure 4 In step S110 of the processing sequence shown in the flowchart, the processing unit 11 of the processing device 1 can also be as follows: Figure 11 The flowchart shows the corrections made in accordance with temperature and aging conditions.

[0093] Figure 12 This is a diagram showing the display mode of the remaining power in the processing device 1 of the third embodiment. Figure 12 The display content shown on the display unit 14 is displayed. The processing unit 11 executes... Figure 4 In the case of the process shown in the flowchart, in the process of step S111, Figure 12 The shape shown indicates the margin, after execution Figure 11 In the case of the process shown in the flowchart, in the process of step S407, Figure 12 The shape shown indicates the allowance. For example... Figure 12 As shown, in the third embodiment, the measured temperature and the aging state of the battery 161 are represented together with the value 142, which indicates the number of medical treatments that can be performed. The aging state is represented by a value that indicates the proportion of the full charge capacity at that point in time when the full charge capacity is set to 100% when the product is new.

[0094] In the third embodiment, a temperature sensor 18 is provided inside the processing device 1, and this temperature sensor 18 is used to measure the temperature inside the device. The temperature used for the above-mentioned calibration is not limited to this, and may also be the room temperature obtained from a separate temperature sensor installed in a designated indoor location via the wireless communication unit 13.

[0095] As shown in the third embodiment, the aging state and temperature that affect the battery 161's power consumption are taken into account to determine the power consumption, and the number of medical treatments that can be performed is calculated, so that the operator can further grasp the remaining power with high precision.

[0096] (Fourth implementation) The processing device 1 in the fourth embodiment has the function of calculating the charging time of the battery 161 until the remaining battery power is sufficient for a medical procedure using the processing device 1. The structure of the image diagnostic system 200 in the fourth embodiment is the same as that of the image diagnostic system 200 in the first embodiment, except for the processing described below. Therefore, for structures in the image diagnostic system 200 of the fourth embodiment that are common to those in the first embodiment, the same reference numerals as in the first embodiment are used, and detailed descriptions are omitted.

[0097] In the fourth embodiment, when the processing unit 11 detects that the power supply unit 16 is connected to the power source via a wired connection, or detects that power reception has begun using the receiving coil, it calculates the time from the start of charging to the end of charging. The processing unit 11 pre-calculates the rate of increase of the charging rate per unit time, or data corresponding to that rate of increase, based on the difference between the charging rate at the start of charging and the charging rate at the end of charging or the time at which full charging is reached, and the elapsed time from the start of charging to the end of charging (or the time at which full charging is reached), and stores this data in the storage unit 12. The processing unit 11 can pre-update the rate of increase or calculate and store statistical values ​​for each charging cycle.

[0098] Figure 13This is a flowchart illustrating another example of the processing sequence executed by the processing apparatus 1 in the fourth embodiment. In the fourth embodiment, the processing unit 11 of the processing apparatus 1 is also as described in the first embodiment. Figure 4 As shown, each time the device is used, the amount of electricity consumed is calculated, and based on the remaining battery level, the number of medical procedures that can be performed after the next use is determined. Furthermore, each time the processing unit 11 calculates the number of medical procedures that can be performed, it executes... Figure 13 The processing shown.

[0099] The processing unit 11 determines whether the calculated number of medical procedures that can be performed is less than a predetermined number (step S501). The predetermined number is, for example, 1 time. If it is determined that the calculated number of medical procedures that can be performed is more than the predetermined number (S501: No), the processing unit 11 does not need to perform the following processing and ends the processing. Even if the number of medical procedures that can be performed is more than the predetermined number, the processing unit 11 may still perform the processing after step S502.

[0100] If it is determined that the calculated number of medical treatments that can be performed is less than the prescribed number (S501: Yes), the processing unit 11 determines the amount of electricity to be used for the prescribed number of treatments (step S502). The processing unit 11 compares the remaining battery power with the amount of electricity to be used for the prescribed number of treatments (step S503) and calculates the amount of electricity required to make the battery 161 have more than the amount of electricity to be used for the prescribed number of treatments (step S504).

[0101] The processing unit 11 calculates the required time for charging with the calculated charge based on the rate of increase of the charging rate per unit time or data corresponding to that rate of increase stored in the storage unit 12 (step S505). The processing unit 11 causes the display unit 14 to display the calculated required time (step S506) and ends the processing. In step S506, the processing unit 11 may also display the time required to increase the number of medical treatments that can be performed by one charge. In step S506, as a warning sound urging charging, the processing unit 11 may also output a beeping sound or a "Please charge" sound using a speaker.

[0102] Figure 14 This is a diagram showing the display mode of the remaining power in the processing device 1 of the fourth embodiment. Figure 14 The display content shown on the display unit 14 is displayed. The processing unit 11 executes... Figure 13 In the process of step S506 shown in the flowchart, in the case of processing, Figure 14 The shape shown indicates the allowance. For example... Figure 14As shown, in the fourth embodiment, along with the metering unit 141 indicating remaining power and the value 142 indicating the number of medical procedures that can be performed, a value 144 is displayed to indicate the time required to perform the procedures at least once (e.g., once). Furthermore, in Figure 14 In the example, the text "Please charge" is displayed.

[0103] The processing device 1 of the fourth embodiment can determine how long the processing device 1 needs to be charged in order to perform a predetermined number of medical procedures using the processing device 1, allowing the operator to plan ahead. Although the time until full charge can also be displayed, for example, by displaying in units of the number of medical procedures that a few minutes of standby time is required before the processing device 1 can be used for at least one medical procedure, the operator can determine the purpose of the processing device 1 without relying on intuition.

[0104] (Fifth implementation) In the fifth embodiment, a menu is implemented that allows viewing the historical data of the power consumption of each processing device 1. The structure of the image diagnostic system 200 in the fifth embodiment is the same as that of the image diagnostic system 200 in the first embodiment, except for the processing described below. Therefore, the common structural elements of the image diagnostic system 200 in the fifth embodiment are labeled with the same reference numerals as in the first embodiment, and detailed descriptions are omitted.

[0105] Figure 15 This diagram shows the appearance of the processing device 1 according to the fifth embodiment. In the processing device 1 of the fifth embodiment, the operation unit 15 includes a power button 151, a scan button 152, and a scroll button 153. In the processing device 1 of the fifth embodiment, a menu is displayed based on the operation performed on the operation unit 15. For example, after pressing the power button 151 to turn on the power, if the scan button 152 is pressed and held down, the menu is displayed on the display unit 14, and the menu can be selected using the scroll button 153.

[0106] Figure 16 This is a flowchart illustrating an example of the processing sequence for displaying and clearing historical records in the processing device 1 of the fifth embodiment. When the processing unit 11 of the processing device 1 detects that the menu for displaying historical records has been selected (step S601), it reads the power usage history from the storage unit 12 (step S602).

[0107] The processing unit 11 determines the amount of electricity used in a single instance based on the read power usage history (step S603). In step S603, the processing unit 11 may also calculate the average (median or mode) of the average amount of electricity used in a single instance after removing outliers and / or isolated values ​​from the previous electricity usage history. The processing unit 11 displays the amount of electricity used determined in step S603 on the display unit 14 (step S604).

[0108] The processing unit 11 determines whether the option to clear the power usage history has been selected from the menu (step S605). If it is determined that clearing has not been selected (S605: No), the processing unit 11 ends the processing.

[0109] If it is determined that clearing has been selected (S605: Yes), the processing unit 11 deletes the historical records of power usage stored in the storage unit 12 (step S606) and ends the processing.

[0110] Through the ability to execute Figure 16 The processing order shown can be reset in the processing device 1 if the accuracy of calculating the number of medical procedures that can be performed based on the historical data of previous power consumption decreases, such as when the type of catheter 2 changes or the order of medical procedures changes.

[0111] (Sixth implementation) In the sixth embodiment, a historical record of power consumption is output to an external device. The structure of the image diagnostic system 200 in the sixth embodiment is the same as that of the image diagnostic system 200 in the first embodiment, except for the structure and processing described below. Therefore, the common structural elements of the image diagnostic system 200 in the sixth embodiment are labeled with the same reference numerals as in the first embodiment, and detailed descriptions are omitted.

[0112] Figure 17 This is a schematic diagram of the image diagnostic system 200 according to the sixth embodiment. The image diagnostic system 200 in the sixth embodiment includes multiple processing devices 1 and a server device 5. The server device 5 is a server computer. The processing devices 1 can send and receive data with the information processing device 4 via wireless communication, and can also send and receive data with the server device 5 via communication.

[0113] Figure 18 This is a block diagram showing the structure of server device 5. Server device 5 includes a processing unit 50, a storage unit 51, and a communication unit 53.

[0114] The processing unit 50 includes one or more processors such as CPU, MPU, GPU, GPGPU, or TPU. The processing unit 50 has built-in non-temporary storage media such as RAM, stores the data generated during processing in the non-temporary storage media, and performs operations based on the computer program P5 stored in the storage unit 51.

[0115] Storage unit 51 is a non-volatile storage medium such as a hard disk or flash memory. Storage unit 51 stores data read by processing unit 50. Storage unit 51 stores the power usage history 501 sent from processing device 1 in each processing device 1.

[0116] The communication unit 53 is a communication device that communicates via wired or wireless means. For example, the communication unit 53 can be any communication device that enables short-range wireless communication with the wireless communication unit 13 of the processing device 1 using a corresponding communication protocol. The communication unit 53 can also be a wired device capable of communicating with the information processing device 4, which is capable of wired communication. The processing unit 50 receives data from the processing device 1 via the communication unit 53.

[0117] In this sixth embodiment, electricity is stored in the server device 5. Figure 19A as well as Figure 19B This is a flowchart illustrating an example of the processing sequence executed by the processing device 1 in the sixth embodiment. During its startup period, the processing unit 11 of the processing device 1 performs the following processing based on the operator's operation received by the operation unit 15. [Regarding...] Figure 19A as well as Figure 19B The processing order shown is the same as that in the first embodiment. Figure 4 The flowcharts shown share a common order, with labels and... Figure 4 The same step numbers are used, and detailed explanations are omitted.

[0118] The processing unit 11 calculates the difference in battery remaining power from startup to shutdown, and the elapsed time from startup to shutdown (S108), and activates the wireless communication unit 13 (step S161). The processing unit 11 sends the calculated power consumption and elapsed time from the wireless communication unit 13 to the server device 5 (step S162). In step S162, the processing unit 11 also sends the identification data of the processing device 1. In step S162, the processing unit 11 may also send the type of catheter 2 used by the processing device 1, the type of medical treatment, and the patient's medical record.

[0119] In step S162, the processing unit 11 may also send the temperature obtained by the temperature sensor and the aging status of the battery 161.

[0120] In the server device 5, when the processing device 1 receives a power consumption record (step S701), the processing unit 50 stores the power consumption record as a power consumption history record 501 in the storage unit 51, corresponding to the identification data of the processing device 1 (step S702). When the processing device 1 receives a case file containing the type of catheter 2, the type of medical procedure, and the patient's condition, the processing unit 50 stores this information corresponding to the power consumption history record 501. Alternatively, the processing unit 50 can obtain the type of catheter 2, the type of medical procedure, and the patient's condition from the information processing device 4, which functions as an image diagnostic device. Furthermore, the information processing device 4 or the server device 5 can pre-store an implementation plan for image diagnostics targeting luminal organs using catheter 2, and identify the type of medical procedure and the patient's condition based on the plan.

[0121] The processing unit 50 calculates the electricity used in one instance based on the power usage history record 501 of the storage unit 51 (step S703) and sends it to the processing device 1 (step S704).

[0122] In step S703, the processing unit 50 calculates, for example, the previous power consumption statistics (average, median, or mode) for each of the plurality of processing devices 1 identified using the identification data. The processing unit 50 may also calculate the previous power consumption statistics for the plurality of processing devices 1 used in the same facility.

[0123] In step S703, the processing unit 50 can also calculate the statistical value of the stored power consumption for each type of catheter 2, the type of medical treatment, and the patient's case for multiple processing devices 1.

[0124] In step S703, the processing unit 50 may also use the information obtained from the internal temperature of the processing device 1 and the aging state of the battery 161 to correct the calculated result of the power consumption once.

[0125] The processing unit 11 receives one charge from the server device 5 (step S163) and stops the wireless communication unit 13 (step S164). Based on the remaining battery level obtained in step S107 and the received charge, the processing unit 11 calculates the number of medical procedures that can be performed in units of the number of medical procedures that can be performed using the processing device 1 (step S165).

[0126] The processing unit 11 displays the calculated number of medical procedures that can be performed on the display unit 14 (S111) and ends the processing. In the sixth embodiment, in step S111, if the calculated number of medical procedures that can be performed is less than a predetermined number, the processing unit 11 may output a beeping sound from the speaker provided by the processing device 1 and make the display unit 14 display a message indicating that there are few remaining procedures.

[0127] In the image diagnostic system 200 of the sixth embodiment, by storing the power consumption using the server device 5, the computing resources used to calculate the power consumption for each operation can be aggregated in the server device 5. Furthermore, by statistically processing the power consumption of multiple processing devices 1, it is expected that the accuracy of calculating the power consumption each time, corresponding to the purpose of each device, can be improved.
