Description

  The present invention relates to a medical imaging system in which an imaging device and an automatic injection device are arranged in an imaging room, and the automatic injection device can be remotely operated outside the imaging room.

  For example, when a magnetic resonance imaging apparatus (MRI imaging apparatus) is used as a medical imaging apparatus, the MRI imaging apparatus is arranged in an electromagnetically shielded imaging room in order to reduce the influence of an external electromagnetic field. Further, when an automatic injection device (injector) for injecting a contrast medium into a patient is used, this injector is also arranged in the imaging room. The shooting room is a space surrounded by a shield wall or the like. The shield wall has a performance of shielding electromagnetic waves in a predetermined frequency band (for example, 1 GHz or less) that may affect photographing.

  There is a technique for improving the degree of freedom of arrangement of a communication interface for exchanging control signals between a device in the photographing room and an outdoor controller (operation device). Specifically, Patent Document 1 discloses a magnetic resonance imaging apparatus disposed in an imaging room surrounded by a shield wall that shields a predetermined frequency band, an injection unit that is disposed in the imaging room and injects a chemical solution, and imaging. A magnetic resonance imaging system is described that includes a controller that is arranged outdoors and that controls the operation of the injection means, and a communication interface for exchanging control signals between the injection means and the controller. In this photographing system, the communication interface is a wireless system that performs communication over the shield wall using a frequency band higher than a predetermined frequency band.

  Hereinafter, exemplary embodiments for carrying out the present invention will be described in detail with reference to the drawings. However, dimensions, materials, shapes, relative positions of components, and the like described in the following embodiments are arbitrary and can be changed according to the configuration of the apparatus to which the present invention is applied or various conditions. Unless otherwise specified, the scope of the present invention is not limited to the embodiments specifically described in the examples described below.

[First Embodiment]
The medical imaging system of FIG. 1 includes a magnetic resonance imaging apparatus (MRI imaging apparatus) 10 as a medical imaging apparatus, and the MRI imaging apparatus 10 is disposed in the imaging room 2. The photographing room 2 is surrounded by a shield wall 3 having an electromagnetic shielding property. As a means for giving the shield wall 3 electromagnetic shielding properties, for example, a metal mesh material or the like can be used. The shield wall 3 is provided with a viewing window for viewing the inside and a door for entering and exiting the room. A machine room 4 is provided adjacent to the radiographing room 2, and a power system and a signal system of the MRI radiographing apparatus 10 communicate from the machine room 4 to the radiographing room 2 via the filter box 5. Further, a ceiling pit 6 is provided above the photography room 2, and an underfloor pit 7 is provided around or below the photography room 2. In the following description, one shooting room 2 will be described, but a plurality of shooting rooms 2 can be provided.

  The MRI imaging apparatus 10 disposed in the imaging room 2 is a conventionally known one, and images a predetermined part of a patient lying on a bed. In addition, an injector 12 that is an automatic injection device for injecting a medical solution such as a contrast medium into a patient is disposed in the imaging room 2. The injector 12 includes a syringe holding unit to which a syringe filled with a chemical solution is mounted, a drive unit that pushes the piston of the syringe toward the cylinder member, a control that controls the operation of the drive unit, and includes a memory, a CPU, and the like. And a circuit. In addition, since the injector 12 of FIG. 1 is hold | maintained on the stand 13 with a caster, it can be moved freely.

  The injection of the drug solution into the patient is automatically performed according to a protocol (injection conditions) set in advance according to the weight of the patient, for example. According to such automatic injection, it is possible to inject an appropriate amount of drug solution to a patient at a preferable injection rate. An operation room 8 is provided outside the photographing room 2. The operation room 8 includes a console 14 as an operation device having a monitor (touch panel monitor) and a keyboard for controlling the operation of the injector 12 and the like. Has been placed. Moreover, the console 14 transmits the operation signal which operates the injector 12 as control information to the main unit 15 as a control apparatus of the injector 12 according to operation by an operator. Examples of the operation signal include an injection start signal and an injection stop signal.

  The console 14 is disposed outside the imaging room 2 and incorporates a communication module 141 described later as a first wireless transmission / reception unit. Both the console 14 and the main unit 15 are connected to an AC power source (AC power source) by a power line 200. However, the console 14 and the main unit 15 may be driven by a built-in battery or a battery attached to the outside. In FIG. 1, a relay unit 16 is provided. The relay unit 16 includes a wireless device 161 that performs transmission and reception with the console 14 via a wireless communication line, and an uninterruptible power supply 162. . The relay unit 16 relays wireless communication between the console 14 and the main unit 15. Therefore, each of the communication module 141 and the wireless device 161 includes the antenna 17 and has a function of transmitting and receiving radio waves. The relay unit 16 receives an operation signal as control information transmitted from the console 14 and transmits the operation signal to the main unit 15 via a control line 150 formed of an optical cable. A control line 150 that connects the relay unit 16 and the main unit 15 passes through the machine room 4. In FIG. 1, a wireless communication line connecting the console 14 and the relay unit 16 is virtually indicated by a dotted line. Further, although the antenna 17 is exposed to the outside, it can be built in the apparatus.

  The main unit 15 is connected to the injector 12 by a power source (DC) -control line 120. Then, the main unit 15 transmits a control signal corresponding to the received operation signal to the injector 12. This control signal is transmitted to the injector 12 via the power supply-control line 120, and the injector 12 performs an operation according to the control signal. For example, the injector 12 starts an injection operation in response to an injection start control signal, or stops the injection operation in response to an injection stop control signal. The main unit 15 may be configured integrally with the injector 12 as one function of the injector 12, or may be attached to the outside of the injector 12 as a separate part.

  In the first embodiment, a wireless system of a predetermined frequency band is used for wireless communication between the console 14 and the relay unit 16, for example, a frequency band of 2 GHz or more, preferably 2.4 GHz to 5 GHz is used. Yes. In general, the frequency band used for imaging by the MRI imaging apparatus is often several hundred MHz. On the other hand, since the wireless system of the first embodiment uses a higher frequency band, this radio wave does not affect the photographing. When using a wireless system, for example, a wireless standard such as wireless USB, MBOA, UWB, ZigBee (registered trademark), or IEEE 802.11 series wireless standards such as Wi-Fi can be used, but Bluetooth (registered trademark) is used. It is preferable to use it. In the following, an example using Bluetooth (registered trademark) will be described unless otherwise specified.

  Since Bluetooth (registered trademark) is omnidirectional, in order to determine which device is being operated, there is a one-to-one correspondence between the operation device (console 14) and the controlled device (main unit 15) in advance. It is necessary to associate with (hereinafter referred to as pairing). That is, pairing means exchanging both IDs (identification information) between the console 14 and the main unit 15.

  As a wireless system, optical wireless communication using visible light, infrared light, or the like can be used. In this case, the console 14 and the relay unit 16 have a light emitting part and a light receiving part. And the console 14 arrange | positioned in the operation room 8 and the relay unit 16 arrange | positioned in the underfloor pit 7 are connected by the optical path via reflection means, such as a reflecting mirror.

  Next, the operation of the medical imaging system according to the first embodiment configured as described above will be described. The operator operates the console 14 and causes the console 14 to read a predetermined injection protocol (condition for injecting a drug solution to the patient) as control information. Further, the operator modifies this injection condition as necessary. For example, the injection conditions can be corrected as appropriate according to the current weight of the patient, the type of chemical to be injected, and the like. In accordance with the operation of the operator, the console 14 transmits the read injection condition data and the injection start operation signal to the main unit 15 via the relay unit 16. Then, the main unit 15 transmits the injection condition data to the injector 12 via the power supply-control line 120.

  Next, the injector 12 performs an injection operation according to the received injection conditions. During the injection operation, the injector 12 sends data on the state of the injection (data such as how much drug solution has been injected into the patient at present) via the main unit 15 and the relay unit 16 as needed. Send to. The console 14 receives this and displays it on the monitor as the injection status in real time. Further, during the injection operation, the console 14 checks whether or not the console 14 and the injector 12 are maintained in a communicable state via the relay unit 16 at predetermined time intervals. If communication is impossible for some reason, the console 14 displays a predetermined alarm on the monitor. Thereby, the operator who confirmed the alarm can stop the injection of the chemical solution by directly operating the injector 12 in the imaging room 2. On the other hand, when the communicable state is maintained, the chemical solution injection is continued, and the injection operation is automatically terminated when a predetermined amount of the chemical solution is injected. When communication is disabled, the console 14 may display an alarm and the main unit 15 may automatically stop the injection of the chemical solution, or a predetermined amount of chemical solution or a total amount of chemical solution may be injected. Also good. Further, the operator can stop the injection of the chemical liquid by a hand switch described later.

  Thus, according to the medical imaging system of the first embodiment, the exchange between the console 14 arranged outside the imaging room 2 and the injector 12 arranged inside the imaging room 2 is transferred to the underfloor pit 7. This can be done via the relay unit 16 arranged. Therefore, it is not necessary to perform communication through the shield wall 3, and the stability of communication does not fluctuate. Therefore, wireless communication between the injector 12 in the photographing room 2 and the console 14 outside the photographing room 2 can be stably performed. Further, even when applied to different shooting rooms 2, wireless communication can be stably connected. Furthermore, since the cable routed between the injector 12 in the photographing room 2 and the console 14 outside the photographing room 2 can be omitted, both can be easily connected.

[Hand switch]
Next, a configuration in which the medical imaging system of the first embodiment includes a wireless hand switch 100 will be described. As shown in FIG. 2, the hand switch 100 includes a Bluetooth (registered trademark) communication module 101 which is a wireless transmission / reception unit. The communication module 101 performs transmission / reception with the Bluetooth (registered trademark) communication module 141 of the console 14. The hand switch 100 includes a built-in battery 102 as a driving power source, a switch unit 103 for operating the injector 12 (for example, an injection start or injection stop operation), a CPU, and the like, and controls the hand switch 100. 1 Chip microcomputer 104. Furthermore, the hand switch 100 includes a display 105 that displays that wireless communication with the console 14 is possible, and the display 105 is configured by an LED lamp or the like. Then, the 1Chip microcomputer determines whether or not pairing is established between the hand switch 100 and the console 14, and turns on the display 105 when the pairing is established.

  On the other hand, the console 14 includes a Bluetooth (registered trademark) communication module 141, a touch panel monitor 142 that functions as an input interface operated by an operator, a 1 chip microcomputer 143 that includes a CPU and controls the console 14, and the injector 12. And an injector control circuit 144 that generates an operation signal as control information. For example, when the operator operates the switch unit 103 of the hand switch 100 and selects the injection stop, the 1Chip microcomputer 104 of the hand switch 100 transmits a signal indicating the injection stop to the console 14 via the communication module 101. The console 14 receives a signal via the communication module 141, and the 1Chip microcomputer 143 causes the injector control circuit 144 to generate an operation signal as control information. Then, the 1Chip microcomputer 143 transmits an operation signal to the receiving device such as the relay unit 16 via the communication module 141.

  By providing the wireless hand switch 100, the operator can operate the injector 12 away from the console 14, and thus the convenience of operation can be enhanced. The hand switch 100 also includes a display 105 that displays that wireless communication with the console 14 is possible. Therefore, the operator can easily determine whether or not the injector 12 can be operated by the hand switch 100. As a result, it is possible to prevent the device from being inoperable during operation by the hand switch 100.

  As a wireless method used for communication between the hand switch 100 and the console 14, optical wireless communication using infrared rays or the like can be used. In this case, the hand switch 100 and the console 14 include a light emitting unit and a light receiving unit instead of the Bluetooth (registered trademark) communication module 101. Then, the 1Chip microcomputer determines whether or not light from the console 14 is received. If the light is received, the display 105 is turned on. The display device 105 may be other display means such as a liquid crystal display panel.

[Both wired and wireless forms]
Next, a configuration in which the medical imaging system according to the first embodiment includes a console 14 that can use both wired and wireless communication methods will be described. As shown in FIG. 3, in the case of a wired system, the console 14 performs serial communication via a power-control line (cable) 160. Therefore, a cable 160 is connected to the serial communication port 145 of the console 14, and an operation signal is transmitted to the main unit 15 via the serial communication-light conversion unit as the relay unit 16. The serial communication-optical conversion unit 16 includes a serial communication port 165 and an optical connector 166, and converts an electrical signal into an optical signal. The main unit 15 also has an optical connector 156, and the main unit 15 and the serial communication-optical conversion unit 16 perform transmission / reception via the optical cable 150 connected to the optical connectors 166 and 156. The operation signal transmitted from the console 14 is received by the serial communication-light conversion unit 16 via the cable 160. The serial communication-light conversion unit 16 converts the received operation signal into an optical signal and transmits it to the main unit 15. The main unit 15 transmits a control signal corresponding to the received operation signal to the injector 12 via the cable 120. Then, the injector 12 performs an operation according to the received control signal.

  In the case of a wireless system, as shown in FIG. 4, a wireless conversion module as a communication module 141 is attached to the serial communication port 145 of the console 14. Specifically, a serial-Bluetooth (registered trademark) conversion module 141 is attached to the serial communication port 145. Then, a Bluetooth (registered trademark) -light conversion unit is disposed as the relay unit 16. The operation signal transmitted from the console 14 is received by the Bluetooth (registered trademark) -optical conversion unit 16 via the serial-Bluetooth (registered trademark) conversion module 141. The Bluetooth (registered trademark) -optical conversion unit 16 converts the received operation signal into an optical signal and transmits the optical signal to the main unit 15 via the optical cable 150. The main unit 15 transmits a control signal corresponding to the received operation signal to the injector 12 via the cable 120. Then, the injector 12 performs an operation according to the received control signal.

  By providing the console 14 that can use both wired and wireless communication methods, the wired method and the wireless method can be switched as necessary. That is, the wired medical imaging system can be easily changed to the wireless system. In addition, the cost for changing to a wireless system can be kept low. The serial communication-light conversion unit 16 and the Bluetooth (registered trademark) -light conversion unit 16 can also be built in the main unit 15.

[Dual console]
Next, a configuration in which the medical imaging system according to the first embodiment includes a plurality of consoles 146 and 147 (dual console) will be described. As shown in FIG. 5, when a dual console is provided, the medical imaging system includes a sub console 147 as another operation device in addition to the main console 146. The sub-console 147 includes a Bluetooth (registered trademark) communication module as a third wireless transmission / reception unit, and can transmit an operation signal to the main unit 15 in accordance with an operation of the operator. The medical imaging system includes a Bluetooth (registered trademark) -light conversion unit as the relay unit 16. The Bluetooth (registered trademark) -optical conversion unit 16 is connected to the main unit 15 via the optical cable 150. The Bluetooth (registered trademark) -light conversion unit 16 is disposed on the side of the operation wall 8 of the shield wall 3. However, the Bluetooth (registered trademark) -light conversion unit may be disposed in the underfloor pit 7, the ceiling pit 6, or the machine room 4.

  When the operator operates the main console 146 or the sub console 147, an operation signal is transmitted to the Bluetooth (registered trademark) -light conversion unit 16 by the communication module. Then, the Bluetooth (registered trademark) -optical conversion unit 16 converts the operation signal into an optical signal and transmits it to the main unit 15 via the optical cable 150. The main console 146 and the sub-console 147 have a touch panel monitor that functions as an input interface. When the injector 12 is operated by the main console 146, the sub console 147 functions as a monitor. On the other hand, when the injector 12 is operated by the sub console 147, the main console 146 functions as a monitor.

  FIG. 6 is a flowchart of pairing processing when a dual console is provided. In the following description, among the main console 146 or the sub-console 147, the console 14 that is first turned on is called a first console, and the console 14 that is turned on next is called a second console. When the power of the first console is turned on, the first console issues a pairing request to the main unit 15 via the relay unit 16 and the optical cable 150. The main unit 15 then responds to the first console pairing request via the relay unit 16 and the optical cable 150. Further, the main unit 15 transmits a control signal instructing activation to the injector 12 via the cable 120, and the injector 12 is activated. Thereafter, the main unit 15 performs pairing with the first console (step 10). As a result, the first console that is powered on first becomes the console 14 that can operate the injector 12.

  Next, when the power of the second console is turned on, the second console issues a pairing request to the first console and the main unit 15. The first console responds to the second console pairing request, and the first console pairs with the second console. On the other hand, since the main unit 15 has been paired with the first console, it rejects the pairing request of the second console (step 11). The second console that is turned on later functions as a monitor that receives information data from the first console that is turned on first and displays the information.

  If pairing switching to the second console does not occur in the state where the main unit 15 and the first console are paired (NO in step 12), the pairing process ends. On the other hand, when the operator selects pairing switching to the second console, the second console issues a pairing cancellation request to the first console. When the pairing between the main unit 15 and the first console can be canceled (YES in step 12), the pairing is canceled (step 13). Then, the second console issues a pairing request to the main unit 15 via the relay unit 16 and the optical cable 150. The main unit 15 responds to the pairing request of the second console via the relay unit 16 and the optical cable 150. Thereafter, the main unit 15 and the second console are paired (step 14). Further, the first console issues a pairing request to the second console and the main unit 15. The second console responds to the pairing request of the first console, and the second console and the first console pair. On the other hand, since the main unit 15 has already been paired with the second console, it rejects the pairing request of the first console (step 15). That is, the second console is a console 14 that can operate the injector 12. The first console functions as a monitor that receives information data from the second console and displays the information. If the pairing between the main unit 15 and the first console cannot be canceled, the pairing process ends (NO in step 12).

  If pairing switching to the first console does not occur while the main unit 15 and the second console are paired (NO in step 16), the pairing process ends. On the other hand, when the operator selects pairing switching, the first console issues a pairing release request to the second console. When the pairing between the main unit 15 and the second console can be canceled (YES in step 16), the pairing is canceled (step 17). Then, returning to step 10, the first console issues a pairing request to the main unit 15, and the main unit 15 and the first console perform pairing. Thereafter, the second console issues a pairing request to the first console and the relay unit 16. The first console responds to the pairing request of the second console, and the first console pairs with the second console (step 10). On the other hand, since the main unit 15 has been paired with the first console, it rejects the pairing request of the second console (step 11). That is, the first console is a console 14 that can operate the injector 12, and the second console is a monitor that displays information of the first console. If pairing between the main unit 15 and the second console cannot be canceled, the pairing process ends (NO in step 16).

  When the dual console is provided, the console for operation and the console for display can be used separately, so that the operability of the console 14 can be improved. Further, by performing the above pairing process, the controlled device can be operated by each console 14 even in a medical imaging system including a dual console. The sub-console 147 may be disposed outside the operation room 8. For example, the sub-console 147 and the relay unit 16 can be connected via a cable, and the sub-console 147 can be arranged in the imaging room 2.

[Relay unit placed in the ceiling pit]
FIG. 7 shows a modification in which the relay unit 16 is arranged in the ceiling pit 6 in the medical imaging system of the first embodiment. In the following description, differences from the above-described configuration will be described in particular, and the same reference numerals will be assigned to the above-described components, and description thereof will be omitted. Except where specifically described, the constituent elements having the same reference numerals perform substantially the same operations and functions, and the effects thereof are also substantially the same.

  In the imaging room 2 of the medical imaging system of FIG. 7, an MRI imaging apparatus 10 (not shown) as a medical imaging apparatus, an injector 12 as an injection apparatus, and a main unit 15 as a control apparatus for the injector 12 are provided. Has been placed. Both the injector 12 and the main unit 15 are held on a stand 13. A console 14 as an operation device is disposed in the operation room 8 outside the imaging room 2. In addition, the console 14 transmits an operation signal as control information for operating the injector 12 to the main unit 15 in accordance with an operation by the operator.

An I / F circuit board 1444 is screwed to the housing 140 of the console 14 so as to face a touch panel module (not shown). That is, when the touch panel module side is the front surface, the I / F circuit board 1444 is provided on the back wall of the housing 140. A first communication module 141 is disposed near the upper corner of the I / F circuit board 1444. The touch panel module (not shown) is provided with a 1Chip microcomputer 143, and the 1Chip microcomputer 143 includes a CPU, a ROM, a RAM, an I / F, and the like. The injector 22 operates in accordance with a program installed in the ROM of the 1Chip microcomputer 143. Further, identification data such as a syringe or an extension tube that can be used is registered in the RAM.

  The first communication module 141 has a chip antenna 1411, and the first communication module 141 is arranged so that the chip antenna 1411 faces upward and outward with respect to the mounting surface of the console 14. The first communication module 141 is opposed to the touch panel module provided with the 1Chip microcomputer 143. A flexible cable 1441 (not shown) connected to the touch panel module is connected to a terminal on the I / F circuit board 1444. By arranging the first communication module 141 in the console 14 in this way, adverse effects on the radio wave characteristics can be suppressed. Note that the antenna 17 may be provided outside the housing 140 separately from the chip antenna 1411. In this case, the housing 140 can be formed of a material having radio wave shielding properties.

  FIG. 32 is a schematic diagram showing the internal configuration of the power supply box 310, with one of the pair of longitudinal walls extending in the longitudinal direction removed. A power supply circuit board 354 for controlling the switching power supply 3523 is screwed to the housing 350 of the power supply box 310. The power supply circuit board 354 provided with the switching power supply 3523 is arranged on the other longitudinal wall extending in the longitudinal direction of the housing 350. Further, the second communication module 21 is disposed on the inner surface of the first side wall 351 of the pair of side walls extending in the direction orthogonal to the longitudinal wall. Note that flange portions projecting toward the housing 350 are provided at both ends of the longitudinal wall and the side wall of the housing 350, and are fixed to each other via the flange portion.

  The antenna 17 is connected to the second communication module 21 via a cable (not shown). And the antenna 17 is arrange | positioned on the outer surface of the 1st side wall 351 in which the 2nd communication module 21 is arrange | positioned at the upper corner vicinity with respect to the mounting surface of the power supply box 310. FIG. Further, a power connector 353 and a connection connector 355 disposed above the power connector 353 are provided on the second sidewall 352 facing the first sidewall 351. The second communication module 21 is disposed at a height substantially opposite to the connection connector 355. The switching power source 3523 is connected to the power connector 353 via a cable (not shown), and is connected to an AC power source via the power line 200. The second communication module 21 is connected to the connection connector 355 via a cable (not shown), and is connected to the injector 22 via the control line 320. By disposing the second communication module 21 and the antenna 17 in this way in the power supply box 310, adverse effects on the radio wave characteristics can be suppressed. Since the antenna 17 is provided outside the housing 350, the housing 350 can be formed of a material having radio wave shielding properties.

  The power supply box 310 may contain a battery or an uninterruptible power supply. According to such a power supply box 310, the operation of the injector 22 can be continued during a power failure or when the power supply line 200 does not reach the external power supply. Further, the power supply box 310 can be disposed on the stand 13. According to such a power supply box 310, when there is much movement inside and outside the imaging room 2, for example, when the injector 22 is moved according to the position of the patient, the control line 320 does not come off.

  Next, in the medical imaging system according to the fifth embodiment, control when communication between the first communication module 141 of the console 14 and the second communication module 21 of the power supply box 310 is interrupted will be described.

  When injecting a chemical solution, the operator operates the console 14 to cause the console 14 to read a predetermined injection protocol. In accordance with the operation of the operator, the console 14 transmits the read injection condition data and the injection start operation signal to the power supply box 310 by the first communication module 141. The power supply box 310 receives the operation signal by the second communication module 21 and transmits it to the injector 22 via the control line 320. Next, the injector 22 generates a control signal according to the received operation signal, and performs an operation according to the control signal. During the injection operation, the injector 22 transmits data related to the injection state to the console 14 via the power supply box 310 as needed. The console 14 receives this and displays it on the monitor as the injection status in real time. During the injection operation, the console 14 checks whether or not the console 14 and the power supply box 310 are maintained in a communicable state at predetermined time intervals.

  As described above, when the chemical solution is injected, the master console 14 and the slave power supply box 310 may be unable to communicate for some reason. In this case, the console 14 and the injector 22 operate so as to restore communication between the console 14 and the power supply box 310. That is, the 1Chip microcomputer 143 (hereinafter referred to as the control unit 143) as the control unit on the console side controls the first communication module 141 so as to restore communication with the second communication module 21. Further, the control device 2144 of the injector 22 that functions as a control device on the injection device side controls the second communication module 21 so as to restore communication with the first communication module 141. The control device 2144 is configured by a 1 chip microcomputer or the like provided in the housing of the injector 22 and controls the injector 22 based on an operation signal transmitted from the power supply box 310.

[Disruption of communication during pairing processing]
FIG. 33 illustrates the control when communication interruption occurs between the first communication module 141 and the second communication module 21 during the pairing process, and between the first communication module 141 and the second communication module 21. Communication is shown. First, the control unit 143 causes the first communication module 141 to transmit a connection request. If the state is normal, the console 14 receives an affirmative response from the power supply box 310, and a connection is established between the first communication module 141 and the second communication module 21. However, if communication is interrupted for some reason, such as the power supply box 310 is not turned on, the power supply box 310 does not respond to the connection request. Therefore, the connection between the console 14 and the power supply box 310 is not established (the STO signal indicating the establishment of the connection remains High). For example, the control unit 143 determines that the connection has not been established when the first communication module 141 does not receive an acknowledgment even though the connection request is transmitted 10 times or 5 times per second.

  In this case, the control unit 143 causes the first communication module 141 to repeatedly transmit a connection request at a predetermined interval for a predetermined time (for example, 1 minute). Then, the control unit 143 causes the touch panel monitor 142 to display an image or characters for informing the operator that the connection is waiting while the first communication module 141 transmits the connection request. Further, when a predetermined time has elapsed, the control unit 143 causes the touch panel monitor 142 to display an image or a character that prompts the operator to check whether the power is on. The confirmation instruction display includes, for example, a text “Please confirm whether the power is on”. When the operator who sees the confirmation instruction turns on the power supply box 310, the control device 2144 causes the second communication module 21 to transmit a positive response to the connection request. When the first communication module 141 receives an affirmative response, the connection between the first communication module 141 and the second communication module 21 is established (the STO signal becomes Low). Then, the control unit 143 turns off the display of the confirmation instruction and proceeds to the next process, and the control for restoring the communication is completed. In the description of FIG. 33, the control unit 143 causes the touch panel monitor 142 to display an image or characters for informing the operator that the connection is waiting. However, the control unit 143 may display a confirmation instruction without displaying an image or characters on the touch panel monitor 142.

[Communication disruption after pairing is established]
FIG. 34 illustrates the control when communication interruption occurs between the first communication module 141 and the second communication module 21 after pairing is established, and between the first communication module 141 and the second communication module 21. Communication is shown. When communication is interrupted for some reason, such as when the power supply box 310 is moved to an area where communication is not possible, the control unit 143 causes the first communication module 141 to transmit a connection request again. However, since communication is interrupted, the power supply box 310 does not respond to the connection request. Therefore, the connection between the console 14 and the power supply box 310 is not established. Thus, when communication is interrupted after pairing is established, the control unit 143 causes the first communication module 141 to repeatedly transmit a connection request at a predetermined interval until the first communication module 141 receives an affirmative response. When the communication interruption is resolved, such as when the power supply box 310 is moved to a communicable area, the control device 2144 causes the second communication module 21 to transmit an affirmative response to the connection request. When the first communication module 141 receives an affirmative response, the connection between the first communication module 141 and the second communication module 21 is established. Then, the control unit 143 proceeds to the next process, and the control for restoring communication is completed.

[Communication disruption in injection idle state 1]
FIG. 35 illustrates the control when a command is transmitted from the console 14 to the power supply box 310 when communication interruption occurs between the first communication module 141 and the second communication module 21 in the injection idle state. . FIG. 35 also shows communication between the first communication module 141 and the second communication module 21. In addition, the injection idle state means a state before and after the chemical liquid injection in which the injector 22 has not injected the chemical liquid. First, in the injection idle state, the control unit 143 causes the first communication module 141 to transmit a command such as an injection start signal. When communication is interrupted for some reason, such as when the power supply box 310 is moved to an area where communication is not possible, the power supply box 310 does not respond to the command. In this case, the control unit 143 causes the first communication module 141 to transmit a connection request again. However, since communication is interrupted, the power supply box 310 does not respond to the connection request. Therefore, the connection between the console 14 and the power supply box 310 is not established. Then, the control unit 143 causes the first communication module 141 to repeatedly transmit connection requests at predetermined intervals until the first communication module 141 receives an affirmative response.

  When the communication interruption is resolved, the control device 2144 causes the second communication module 21 to transmit an affirmative response to the connection request. When the first communication module 141 receives an affirmative response, the connection between the first communication module 141 and the second communication module 21 is established. Then, the control unit 143 causes the first communication module 141 to transmit a disconnection notification command for notifying that communication has been interrupted. When the second communication module 21 receives the disconnection notification command, the control device 2144 causes the first communication module 141 to transmit the disconnection notification command to the second communication module 21. Further, the control device 2144 transmits a disconnection notification command and temporarily stops the operation of the injector 22. Furthermore, the control device 2144 shifts the injector 22 to the check mode and prohibits the release of the check mode. Here, the check mode is a mode for prohibiting the injection of the chemical until the preparation for injection is completed. The check mode can be canceled by pressing the check button on the injector 22 or the console 14. Normally, the operator presses the check button after completing the preparation for injection.

  On the other hand, when the first communication module 141 receives the disconnection notification command, the control unit 143 of the console 14 sends an information request command for requesting the information (injection device information) of the injector 22 to the second communication module 21. 141 to transmit. When the second communication module 21 receives the information request command, the control device 2144 causes the first communication module 141 to transmit the current information of the injector 22 to the second communication module 21. The control unit 143 acquires the received information on the injection device, and creates and sends a command command corresponding to the state of the injection device. Further, based on the acquired information, the control unit 143 determines whether or not it is possible to inject a chemical solution, and if it is determined that injection is possible, causes the first communication module 141 to transmit a reconnection command. Further, when there is an operation for stopping injection by the hand switch 100 during communication interruption, the control unit 143 causes the first communication module 141 to transmit a switch command for stopping injection to the power supply box 310. Thereby, injection | pouring of a chemical | medical solution can be stopped after communication interruption is eliminated.

  When receiving the reconnection command, the control device 2144 causes the second communication module 21 to transmit the reconnection command. In addition, the control device 2144 sets the injector 22 to be operable. On the other hand, when the control unit 143 receives the reconnection command, the control unit 143 deletes the connection waiting state and sets the console 14 so that the injector 22 can be operated. Thereafter, when injecting a chemical solution, the operator depresses the check button of the injector 22 or the console 14 to cancel the check mode. Thereby, it becomes possible to shift from the injection idle state to the injection state, and the control for restoring the communication is completed.

  Thus, the operation of the injector 22 is temporarily stopped and the injector 22 shifts to the check mode, so that the chemical liquid can be prevented from being injected during the communication interruption, and the chemical liquid can be injected more safely. Note that the control device 2144 can also stop the operation of the injector 22 and prohibit manual operation of the injector 22. Further, the control device 2144 may simply shift the injector 22 to the check mode without prohibiting the release of the check mode. In this case, the check mode can be canceled by pressing the check button of the injector 22 or the console 14.

  The injector 22 information includes injector 22 status information, check mode on / off information, standby mode on / off information, information on syringes attached to the injectors 22, IC tag attachment / non-attachment information, and chemical injection. Status information, phase information for chemical injection, and the like. Furthermore, the status information of the injector 22 includes an initialization state, an injection idle state, a manual movement state of the plunger, an injection state, an injection pause state, an injection stop state, an injection end state, a warning state, an error state, etc. Information indicating that there is an injector 22 is included. The syringe information includes information indicating the type of syringe, the mounting / non-mounting of the syringe, the remaining amount of the chemical in the syringe, and the like. The injection status information includes information indicating that the injector 22 is present in the injection delay state, the injection state, the injection standby state, and the like.

[Communication disruption in injection idle state 2]
FIG. 36 illustrates control when a command is transmitted from the power supply box 310 to the console 14 when communication interruption occurs between the first communication module 141 and the second communication module 21 in the injection idle state. . FIG. 36 also shows communication between the first communication module 141 and the second communication module 21. First, in the injection idle state, the control device 2144 causes the second communication module 21 to transmit a command such as an injection protocol transmission request. When communication is interrupted for some reason, such as when the power supply box 310 is moved to an area where communication is not possible, the console 14 does not respond to the command. In this case, the control device 2144 causes the injector 22 to wait until the second communication module 21 receives the connection request. On the other hand, the control unit 143 causes the first communication module 141 to repeatedly transmit connection requests at predetermined intervals until the first communication module 141 receives an affirmative response.

  When the communication interruption is eliminated and the second communication module 21 receives the connection request, the control device 2144 causes the second communication module 21 to transmit an affirmative response to the connection request. When the first communication module 141 receives an affirmative response, the connection between the first communication module 141 and the second communication module 21 is established. Then, the control device 2144 causes the second communication module 21 to transmit a disconnection notification command for notifying that communication has been interrupted. Further, the control device 2144 temporarily stops the operation of the injector 22, shifts the injector 22 to the check mode, and prohibits the release of the check mode.

  When the first communication module 141 receives the disconnection notification command, the control unit 143 causes the first communication module 141 to transmit an information request command for requesting information on the injector 22. When the second communication module 21 receives the information request command, the control device 2144 causes the first communication module 141 to transmit the current information of the injector 22 to the second communication module 21. The control unit 143 acquires the received information on the injection device, and creates and sends a command command corresponding to the state of the injection device. Further, based on the acquired information, the control unit 143 determines whether or not it is possible to inject a chemical solution, and if it is determined that injection is possible, causes the first communication module 141 to transmit a reconnection command. Further, when there is an operation to stop injection by the hand switch 100 during communication interruption, the control unit 143 causes the first communication module 141 to transmit a switch command to stop injection.

  When receiving the reconnection command, the control device 2144 causes the second communication module 21 to transmit the reconnection command. In addition, the control device 2144 sets the injector 22 to be operable. Upon receiving the reconnection command, the control unit 143 sets the console 14 so that the connection wait state display is turned off and the injector 22 can be operated. Then, when inject | pouring a chemical | medical solution, an operator cancels | releases check mode by pushing the check button of the injector 22 or the console 14. FIG. Thereby, it becomes possible to shift from the injection idle state to the injection state, and the control for restoring the communication is completed.

[Communication disruption during injection]
FIG. 37 illustrates control when a command is transmitted from the power supply box 310 to the console 14 when communication interruption occurs between the first communication module 141 and the second communication module 21 during injection of the chemical solution. . FIG. 37 also shows communication between the first communication module 141 and the second communication module 21. First, in the injection state, the control device 2144 causes the second communication module 21 to transmit a command or the like indicating the remaining amount of the chemical solution. When communication is interrupted for some reason, such as when the power supply box 310 is moved to an area where communication is not possible, the console 14 does not respond to the command. In this case, the control unit 143 causes the first communication module 141 to repeatedly transmit connection requests at predetermined intervals until the first communication module 141 receives an affirmative response.

  When the communication interruption is eliminated and the second communication module 21 receives the connection request, the control device 2144 causes the second communication module 21 to transmit an affirmative response to the connection request. When the first communication module 141 receives an affirmative response, the connection between the first communication module 141 and the second communication module 21 is established. Then, the control device 2144 causes the second communication module 21 to transmit a disconnection notification command for notifying that communication has been interrupted. At this time, the control device 2144 continues the operation of the injector 22 while the communication is interrupted, and the chemical solution is continuously injected. That is, when communication is interrupted during the injection of the chemical solution, the control device 2144 controls the second communication module 21 to transmit a disconnection notification command and continues the operation of the injector 22.

  When the first communication module 141 receives the disconnection notification command, the control unit 143 causes the first communication module 141 to transmit an information request command for requesting information on the injector 22. When the second communication module 21 receives the information request command, the control device 2144 causes the first communication module 141 to transmit the current information of the injector 22 to the second communication module 21. At this time, the control device 2144 deletes (overwrites) information while communication is interrupted, and transmits the current information of the injector 22. The control unit 143 acquires the received information on the injection device, and creates and sends a command command corresponding to the state of the injection device. Further, the control unit 143 determines whether or not the chemical solution can be injected based on the acquired information. If the control unit 143 determines that the injection is possible, the control unit 143 causes the first communication module 141 to transmit a reconnection command. Further, when there is an operation for stopping injection by the hand switch 100 while communication is interrupted, the control unit 143 causes the first communication module 141 to transmit a switch command for stopping injection to the power supply box 310. When receiving the reconnection command, the control device 2144 causes the second communication module 21 to transmit the reconnection command. When the reconnection command is received, the control unit 143 turns off the connection waiting state display. This completes the control for restoring communication.

  As described above, since the injection of the chemical liquid is continued even while the communication is interrupted, it is not necessary to reinject the chemical liquid. Therefore, the burden given to the patient's body can be reduced. Further, since the control device 2144 deletes information while communication is interrupted, the storage area can be reduced. Note that the control unit 143 calculates a scheduled injection end time, and displays an error display on the touch panel monitor 142 when communication is not recovered even after the scheduled time has passed. Further, the control device 2144 may temporarily stop the operation of the injector 22 and shift the injector 22 to the check mode instead of continuing the injection. Alternatively, the control device 2144 may display a selection image indicating whether or not the operation of the injector 22 is stopped on the touch panel monitor 142 instead of continuing the injection. In addition, the operator can select whether or not to stop the operation of the injector 22 by an initial setting in advance.

  Further, if there is a margin in the storage area, the control device 2144 may store information while communication is interrupted and may transmit the information to the second communication module 21 as information on the injector 22. Furthermore, when a leak sensor attached to the patient's body detects a leak of the chemical solution while communication is interrupted, the leak sensor transmits a command to stop the injection to the console 14 or the injector 22 by wire or wirelessly. You can also. Thereby, injection | pouring can be made to the injector 22 when the leak of a chemical | medical solution arises.

[If the status does not match]
In FIG. 37, when the console 14 acquires the information of the injector 22, the control when the status based on the information is different from the status predicted by the control unit 143 of the console 14 will be described with reference to FIG. FIG. 38 also shows communication between the first communication module 141 and the second communication module 21. For example, the case where the statuses are different is a case where information indicating the end of injection is included in the information of the injection device, contrary to the fact that the control unit 143 predicts that the injection is in progress. Until the information request command is transmitted, it is the same as the example shown in FIG.

  First, the control unit 143 of the console 14 predicts the current status of the injector 22 based on the injection protocol. Further, the control unit 143 of the console 14 compares the status of the injector 22 based on the acquired information of the injector 22 with the predicted status. If the status is different from the predicted status, the control unit 143 of the console 14 causes the second communication module 21 to transmit an initialization command to the first communication module 141. When the second communication module 21 receives the initialization command, the control device 2144 initializes the injector 22 and causes the second communication module 21 to transmit the initialization command. When the first communication module 141 receives the initialization command, the control unit 143 initializes the console 14. After completion of the initialization process, the injector 22 and the console 14 shift to the injection idle state. This completes the control for restoring communication.

  The initialization process is a process for resetting and restarting the console 14 and the injector 22. Thereby, the console 14 and the injector 22 shift to the injection idle state through the module search and the pairing process. Therefore, even if the status indicated by the information acquired by the console 14 and the status predicted by the control unit 143 of the console 14 are different and it is not possible to determine which is correct, the console 14 and the injector 22 Can be transferred to the injection idle state. If it can be determined that one of the statuses is correct, the control unit 143 or the control device 2144 may change the status according to the correct status.

  The above-described control described in the examples of FIGS. 33 to 38 is realized by a program mounted on a computer-readable internal recording medium such as a ROM of the control unit 143 or the control device 2144. That is, the control is realized by the program causing the control unit 143 or the control device 2144 to execute the processes described above. The program may be stored in a computer-readable external recording medium. In this case, the control is realized by a program read by the control unit 143 or the control device 2144 from the external recording medium.

  According to the medical imaging system of the fifth embodiment described above, communication can be restored without adversely affecting the injection of the chemical solution even when communication is interrupted. In the medical imaging system of the fifth embodiment, the power supply box 310 having the antenna 17 is arranged away from the stand 13 of the injector 22. Thereby, the position where the power supply box 310, that is, the antenna 17 is arranged is not limited to the vicinity of the patient. Therefore, even if the communication environment is poor near the patient, the power supply box 310 can be moved to a place in the imaging room 2 where the communication environment is good.

  Further, in the example of FIGS. 33 to 38, the control when the communication between the console 14 and the power supply box 310 is interrupted has been described. However, the console 14 can perform similar control even when communication with other devices such as the hand switch 100 is interrupted. The number of devices that communicate with the console 14 is not limited to one, and the console 14 and two or more devices may communicate simultaneously.

  In addition, the power supply box 310 can also be comprised integrally with the injector 22, and can also be comprised so that attachment or detachment with respect to the injector 22 is possible. Further, a portable general-purpose display device can be connected to the console 14 instead of the touch panel of the console 14. In this case, the injector 22 is operated according to an operation signal input via the general-purpose display device. Furthermore, it can replace with the 1st communication module 141 and the 2nd communication module 21, and can also use the 1st and 2nd optical wireless communication unit. Moreover, the injector 22 can also be suspended from a ceiling.

  Furthermore, the injector 22 can be provided with a second communication module 21. In this case, the injector 22 can be directly operated by the wireless hand switch 100. In addition, a portable touch panel module can be attached to the injector 22 or the stand 13 as an operation device. In this case, the operator can operate the injector 22 at an arbitrary place by using the touch panel module. In addition, the touch panel module as an operation device is provided integrally with the injector 22 and can also be used as a display operation device. In addition, the display operation device may be movably connected to the injector 22.

  Further, the control of the fifth embodiment is applied to the control in the case where the communication between the console and the main unit, the relay unit, or the optical wireless communication unit is interrupted in the first to fourth embodiments and the modifications. You can also. For example, if the connection between the console wireless transmission / reception unit and the relay unit is established after the communication between the console wireless transmission / reception unit and the relay unit is interrupted, the control device disconnects the communication to the console wireless transmission / reception unit. A disconnection notification command for notifying the user that the operation has been performed can be transmitted to the relay unit. Further, after the communication between the first optical wireless communication unit and the second optical wireless communication unit is interrupted, the connection between the first optical wireless transmission / reception unit and the second optical wireless communication unit is established. The control device can cause the second optical wireless communication unit to transmit a disconnection notification command that notifies the first optical wireless communication unit that communication has been interrupted.

[Linkage between medical imaging device and injection device]
Next, with reference to FIG. 30, the linkage between the medical imaging apparatus (CT imaging apparatus 20) and the injection apparatus (injector 22) in the medical imaging system of the fifth embodiment will be described.

  The CT imaging apparatus 20 of this modification includes an imaging apparatus side communication module as a wireless transmission / reception unit (not shown). When the injection of the chemical liquid is started, the power supply box 310 transmits a signal indicating that the injection of the chemical liquid is started to the CT imaging apparatus 20 via the second communication module 21. Then, the CT imaging apparatus 20 receives the signal via the imaging apparatus side communication module. In addition, when the injection of the chemical solution is started, the operator can operate the CT imaging device 20 and transmit an operation signal to the power supply box 310 to start the injection of the chemical solution via the imaging device side communication module. The power supply box 310 that has received the operation signal transmits the operation signal to the injector 22 and the injection of the chemical solution is started. When the injection of the chemical liquid is started, the power supply box 310 transmits a signal indicating that the injection of the chemical liquid is started to the CT imaging apparatus 20 via the second communication module 21.

  Further, during the injection of the chemical solution, the power supply box 310 transmits information indicating the injection status of the chemical solution to the CT imaging device 20 via the second communication module 21. Specifically, the power supply box 310 transmits information such as an injection rate, an injection amount, an injection time, and a phase time.

Furthermore, exposure can be suppressed by the console 14 transmitting to the RFID information CT imaging apparatus 20 of the chemical solution and the CT imaging apparatus 20 setting the X-ray dose in advance. Furthermore, the console 14 can transmit injection result information including a pressure graph to PACS, HIS, RIS, etc., and record the information. Thereby, chemical | medical solution information (RFID information) can be attached to the image data etc. from CT imaging device 20. FIG. The transmitted RFID information can also be used for accounting for chemicals. The medical imaging apparatus that can be used in the present modification is not limited to the CT imaging apparatus, and various imaging apparatuses such as an angio imaging apparatus can also be used. In addition, the console 14 and the injector 22 can be connected to a plurality of different medical imaging devices by wire or wirelessly. For example, the console 14 and the injector 22 can be connected to a CT imaging apparatus and an angiography apparatus by wire or wirelessly. In this case, an injector for the CT imaging apparatus and an injector for the angio imaging apparatus can be used. Furthermore, the console 14 and the injector 22 can be connected to PACS, HIS, RIS, etc. by wire or wirelessly.
