Abstract

<P>PROBLEM TO BE SOLVED: To provide a medical diagnostic imaging apparatus which wirelessly communicates signals relating to a sensor system or an operation system by using short distance radio communication. <P>SOLUTION: Input signals generated by a console 21 are sent from a radio communication section B19 and received by a radio communication section A17. A main control section 11 arithmetically processes the received input signals and controls the processed signals so as to return them to the console 21 through the radio communication section B19. Thus since the input signals generated on the console 21 are wirelessly communicated through the radio communication section B19, this helps wiring in the instrument to be saved in the apparatus 1. Since the radio communication sections A17 and B19 send and receive signals by short-distance radio communication, the radio communication sections are made less susceptible to radio waves caused by radio equipment installed in other rooms and medical equipment such as pacemakers beyond a laboratory 7 in which radiographing is carried out by using the apparatus 1. <P>COPYRIGHT: (C)2009,JPO&INPIT

The input unit 23 outputs the content input by the operator to the input / output signal control unit 25 as an input signal. The input / output signal control unit 25 converts the input signal input from the input unit 23 into a pulse signal, and outputs the pulse signal to the wireless communication unit A 17 disposed in the examination room 7. The input / output signal control unit 25 and the wireless communication unit B19 may be connected by cable or may be connected using high-speed power line communication (PLC) for further wiring saving. The wireless communication unit B19 modulates the pulse signal input from the input / output signal control unit 25 into an electromagnetic wave for wireless communication, and transmits the electromagnetic wave to the wireless communication unit A17 disposed in the examination room 7. For convenience of illustration, wireless communication is indicated by a broken line arrow, and wired communication is indicated by a solid line arrow. The output unit 27 causes the output unit 27 to display the current operation status of the apparatus main body 3 with a monitor display or an LED lamp.

  A trolley-equipped console 22 disposed in the examination room 7 includes an input unit 24 that inputs an up / down operation of the bed unit 4, an input / output signal control unit 26 that converts an input signal into a pulse signal, and a pulse signal.

The wireless communication unit J38 corresponds to the first wireless communication unit of the present invention.

  The bedside operation panel 15 disposed in the examination room 7 includes an input unit 29 that inputs an up / down operation of the bed unit 4, an input / output signal control unit 31 that converts an input signal into a pulse signal, and a pulse signal. A wireless communication unit C33 that modulates the wireless communication and an output unit 35 that displays an operation status of the bed unit 4. The wireless communication unit C33 is connected to the input / output signal control unit 31 by wire and performs wireless communication with the wireless communication unit A17 attached to the wall surface of the examination room 7. The wireless communication unit C33 corresponds to the first wireless communication unit of the present invention.

  In the apparatus main body 3 arranged in the operation chamber 9, a motor A12 that horizontally or rotationally drives a holding unit 10 that holds the X-ray tube 6 and the X-ray detector 8 shown in FIG. A potentiometer A14, a motor B18 that drives the bed 4 to move up and down, and a potentiometer B20 that detects a vertical drive amount.

  The main control unit 11 disposed in the machine room 5 is connected to the wireless communication unit A17 with a cable, modulates an electromagnetic wave received from the wireless communication unit A17 into a pulse signal, performs calculation processing, and outputs a control signal. For example, when an input signal is received from the bedside operation panel 15, the operation console 21, or the operation console with carriage 22 via the wireless communication unit A17 and the wireless communication unit B19, the holding unit 10 and the bed shown in FIG. A control signal for driving the unit 4, the high voltage generating unit 13, and the like is output. The sensors attached to these driving units output sensor signals to the main control unit 11. The main control unit 11 outputs the input sensor signal to the bedside operation panel 15, the operation console 21, and the operation console 22 with a carriage via the wireless communication unit A 17 and the wireless communication unit B 19, and outputs them to the output units 27, 28, and 35. The current operation status of the apparatus main body 3 is displayed.

  Short-range radio is used for the radio communication unit A17 and the radio communication unit B19. For example, a wireless communication module using a standard called IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 802.15.4, commonly called ZIGBEE (registered trademark) (Koninklijke Philips Electronics N.V.). A commercially available level is sufficient for this, but it is safe to select a module that has undergone radio law certification. Since ZIGBEE (registered trademark) (Koninklijke Philips Electronics N.V.) has a short communication reach, only wireless communication within one room can be established. As described above, since the input signal is transmitted and received by the short-range wireless communication, it is difficult to be affected by radio waves generated by wireless devices and medical devices such as pacemakers provided in other rooms beyond the examination room 7.

  When the examination room 7 is large, even within one room, the distance between the wireless communication unit A17 and the wireless communication unit B19 is long, and thus direct wireless communication may not be possible. In that case, as shown in FIG. 2, wireless communication units D37 and E39 for relaying wireless communication are provided between paths connecting the wireless communication unit A17 and the wireless communication unit B19. The wireless communication unit D37 and the wireless communication unit E39 correspond to the relay unit of the present invention.

  When wireless communication is performed between the trolley-equipped console 22 and the main control unit 11, electromagnetic waves transmitted wirelessly from the wireless communication unit J38 to the wireless communication unit A17 are blocked by the holding unit 10 of the apparatus main body 3. Similarly, when wireless communication is performed between the bedside operation panel 15 and the main control unit 11, electromagnetic waves transmitted wirelessly from the wireless communication unit C <b> 33 to the wireless communication unit A <b> 17 are blocked by the holding unit 10 of the apparatus body 3. . In this case, as shown in FIG. 3, the wireless communication unit D37 is disposed on the ceiling of the examination room 7, and the path connecting the wireless communication unit C33 or the wireless communication unit J38 and the wireless communication unit A17 is held by the apparatus main body 3. Do not block with shielding objects such as part 10. The radio communication unit D37 disposed above the radio communication unit C33 or the radio communication unit J38 receives the electromagnetic wave, and transmits the electromagnetic wave to the radio communication unit A17.

  In the first embodiment, the wireless communication units A17, B19, C33, D37, E39, and J38 are connected in a mesh shape. As shown in FIG. 4, the wireless communication unit J38 has wireless communication paths with the wireless communication units A17, B19, C33, D37, and J38, respectively, but the holding unit 10 of the apparatus main body 3 is in the position shown in FIG. When stationary, since the communication path between the wireless communication unit J38 and the wireless communication unit A17 is not communicable, another route is selected avoiding this route. As another route, in FIG. 3, a route for wireless communication with the wireless communication unit A17 by selecting the wireless communication unit D37 is selected. Although there is a route for relaying wireless communication with the wireless communication unit A17 via the wireless communication unit B19, it takes longer than the route for selecting the wireless communication unit D37, so the route for relaying the wireless communication unit D37 is selected. Since the electromagnetic wave that relays the wireless communication unit C33 is blocked by the holding unit 10 in the route that relays the wireless communication unit C33, the wireless communication unit J38 does not select this route. Next, when the holding unit 10 is stationary at the position illustrated in FIG. 4, a path connecting the wireless communication unit J38 and the wireless communication unit A17 can be communicated. Since the route connecting the wireless communication unit J38 and the wireless communication unit A17 can transmit a signal to the main control unit 17 in a shorter time than other routes, the wireless communication unit J38 selects this route.

  Although not shown in FIG. 4, the wireless communication unit C33 is also connected to the wireless communication units A17, B19, D37, and J38 in a mesh shape. In FIG. 3, a route for wireless communication with the wireless communication unit A17 is selected by relaying the wireless communication unit D37 while avoiding a route where communication is impossible. Since the wireless communication unit C33 selects a route through which a signal can be transmitted to the main control unit 17 in a short time, the wireless communication unit C33 relays the wireless communication unit J38 and selects a route for wireless communication with the wireless communication unit A17.

  Also in FIG. 5, the wireless communication unit B19, the wireless communication unit C33, the wireless communication unit J38, and the wireless communication unit A17 are connected in a mesh shape. As shown in FIG. 3, when the holding unit 10 blocks wireless communication, the wireless communication unit A <b> 37 relays wireless communication with the wireless communication unit A <b> 17. In FIG. 5, when the wireless communication unit C33 is not blocked by the holding unit 10, the wireless communication unit 19, the wireless communication unit C33, and the wireless communication unit J38 are star-connected with the wireless communication unit A17 as a center.

  The wireless communication units B19 and J38 and the wireless communication unit A17 are called an ARCNET (Attached Resource Computer Network) and are wirelessly an improved token passing system network protocol certified by ANSI (the American National Standard Institute) 878.1. connect. The feature of ARCNET is that transmission right data called a token is transmitted in the network, and the wireless communication units A17, B19, C33 can transmit data only when this token is received. Therefore, when the wireless communication unit B19 receives the token and transmits data to the wireless communication unit A17, the wireless communication unit J38 is configured not to transmit data to the wireless communication unit A17.

  According to the device 1 according to the first embodiment, an input signal generated by the bedside operation panel 15 or the console 21 is transmitted from the wireless communication unit B19 or C33 and received by the wireless communication unit A17. The main control unit 11 performs calculation processing on the received input signal, and controls the processed signal to be returned to the bedside operation panel 15 or the console 21 via the wireless communication units A17 and B19. Thus, since the input signal generated on the bedside operation panel 15 or the console 21 is wirelessly communicated via the wireless communication units A17, B19, and C33, the wiring in the apparatus 1 can be reduced. Furthermore, since the wireless communication unit A17 is disposed on the inner wall surface of the same room as the room where the wireless communication unit D37 or the wireless communication unit E39 is disposed, wireless communication can be easily performed even when performing wireless communication.

  According to the apparatus 1 according to the first embodiment, wireless communication is performed via the wireless communication unit E39 between the wireless communication unit A17 and the wireless communication unit B19. Wireless communication can be easily performed even when they are arranged apart from each other, and wiring saving can be measured.

  According to the device 1 according to the first embodiment, even when a route connecting the wireless communication unit A17 and the wireless communication unit B19 is blocked by the device body 3, the wireless communication unit E39 is disposed between the routes to perform wireless communication. Therefore, the wiring saving can be measured between the operation console 22 with the carriage and the main control unit 11 regardless of the device configuration.

  According to the apparatus 1 according to the first embodiment, the paths connecting the wireless communication unit A17, the wireless communication unit B19, the wireless communication unit D37, the wireless communication unit E38, and the wireless communication unit E39 are respectively connected in a mesh shape. Since each means can directly communicate with other means, signals relating to the sensor system or the operation system can be connected to one path, for example, a path connecting the radio communication units C33, A17 or the radio communication units C33, E39, A17. Even if the route becomes incapable of communication, communication is performed by selecting another communicable route, for example, a route connecting the wireless communication units C33, D37, E39, and A17. As a result, wireless communication can be performed even when a signal to be wirelessly communicated is deeply blocked by the shielding object, so that wiring saving can be achieved regardless of the configuration of the device 1.

  According to the apparatus 1 according to the first embodiment, since the path connecting the wireless communication unit A17 and the wireless communication unit B19 is star-connected around the wireless communication unit A17, the bedside operation panel 15, the console 21 and the carriage are attached. Wireless communication is possible regardless of the increase or decrease of the console 22. As a result, it is possible to save wiring regardless of the configuration of the device 1.

  According to the apparatus 1 according to the first embodiment, the path connecting the wireless communication unit A17 and the wireless communication unit B19 is star-connected around the wireless communication unit A17 via the wireless communication units D37 and E39. When the number of the panel 15, the console 21 and the operation console 22 with a carriage is increased or decreased, even when the apparatus main body 3 is on the path connecting the wireless communication unit A17 and the wireless communication unit B19, the wireless communication units D37 and E39 are used. Wireless communication is possible, and wiring saving can be measured between the bedside operation panel 15, the operation console 21, the operation console with carriage 22 and the main control unit 11 regardless of the device configuration.

  According to the apparatus 1 according to the first embodiment, the wireless communication unit A17 and the wireless communication units B19, C33, and J38 are star-connected around the wireless communication unit A17, and the route connecting the wireless communication unit A17 and the wireless communication unit C33. Is relayed by the wireless communication unit J38. In addition, a wireless communication unit D37 is provided via a star-connected path as necessary for the apparatus body 3. Therefore, when there is an obstruction on the path connecting the wireless communication unit A17 and the wireless communication unit C33, or when the wireless communication unit C33 or the wireless communication unit J38 is added, direct wireless communication cannot be performed with the wireless communication unit A17. Sometimes, wireless communication can be performed via the wireless communication unit J38 and the wireless communication unit D37, and the wiring is reduced from the bedside operation panel 15, the console 21, the operation console 22 with a carriage to the main control unit 11 regardless of the device configuration. Can be measured.

  According to the apparatus 1 according to the first embodiment, signals are wirelessly communicated between the bedside operation panel 15, the operation console 21, the operation console 22 with a carriage, and the main control unit 11. be able to.

  Since the contents described in the device 1 according to the first embodiment also correspond to the second embodiment, the same effects as the first embodiment are produced.

  Next, Embodiment 3 of the present invention will be described with reference to the drawings. FIG. 8 is a schematic diagram illustrating a characteristic portion of the X-ray fluoroscopic apparatus according to the third embodiment. Since the X-ray fluoroscopic apparatus is the same as the X-ray fluoroscopic apparatus 1 according to the first embodiment, the description thereof is omitted.

  As shown in FIG. 8, the X-ray fluoroscopic apparatus 1 (hereinafter referred to as “apparatus 1”) according to the third embodiment has a bed section 4 on which a subject P is placed in addition to the configuration of the apparatus 1 that is not described. Of the bedside operation panel 15 between the bedside operation panel 15 attached to either the left or right in the longitudinal direction of the bed part 4, the wireless communication unit C33 provided in the bedside operation panel 15, and the wireless communication unit C33. A wireless communication unit H81 and a wireless communication unit I83 that wirelessly communicate an input signal, an attachment side determination unit J85 that determines whether the bedside operation panel 15 is attached to the left or right side in the longitudinal direction of the bed unit 4, and an attachment side determination unit K87 and an operation direction changing unit 89 that changes the operation direction of the apparatus 1 as necessary. The attachment side determination units J85 and K87 and the operation direction changing unit 89 are provided in the main control unit 11.

  The case where the radio communication unit I83 is attached to the left side L in the longitudinal direction of the bed unit 4 will be described. The wireless communication unit I83 is disposed on the examination room wall 84 facing the wireless communication unit C33. When an operation lever 82 provided on the bedside operation panel 15 is operated, an input signal (hereinafter referred to as an attachment side signal) is wirelessly transmitted to the wireless control unit I83.

  When the bedside operation panel 15 is attached to the L side, the wireless communication unit C33 and the wireless communication unit H81 cannot perform wireless communication. This is because the attachment side signal wirelessly transmitted from the wireless communication unit C33 is blocked by the device 1 and does not reach the wireless communication unit H81. Therefore, when the bedside operation panel 15 is attached to the L side, the attachment side signal wirelessly communicated from the wireless communication unit C33 is always wirelessly transmitted to the wireless communication unit I83.

  When the attachment side determination unit K87 receives the attachment side signal transmitted by wire from the wireless communication unit I83, the attachment side determination unit K87 determines that the bedside operation panel 15 is attached to the L side and notifies the operation direction changing unit 89 of the attachment side determination signal. Is sent by wire.

  When receiving the attachment side determination signal from the attachment side determination unit K87, the operation direction changing unit 89 determines that the bedside operation panel 15 is attached to the reference position and does not change the operation direction of the apparatus 1.

  Next, the case where the radio communication unit H81 is attached to the bedside operation panel 15 at the right side R in the longitudinal direction of the bed unit 4, that is, the position illustrated by the broken line will be described. The wireless communication unit H81 is disposed on the examination room wall 84 facing the wireless communication unit C33. When an operation lever 82 provided on the bedside operation panel 15 is operated, an attachment side signal is wirelessly transmitted to the wireless control unit H81.

  The attachment side determination unit J85 receives an attachment side signal transmitted by wire from the wireless communication unit H81. When the attachment side determination part J85 receives the attachment side signal, the bedside operation panel 15 is attached to the R side in the longitudinal direction of the bed part 4. Therefore, the attachment side determination unit J85 determines that the bedside operation panel 15 is attached to the R side, and transmits the attachment side determination signal to the operation direction changing unit 89 by wire.

  When receiving the attachment side determination signal from the attachment side determination unit J85, the operation direction changing unit 89 determines that the bedside operation panel 15 is attached at a position different from the reference position, and reverses the operation direction of the device 1.

  In the apparatus 1, when the bedside operation panel 15 is on the L side is set as the reference position, when the bedside operation panel 15 is attached to the left side L in the longitudinal direction of the bed part 4, the operation lever 91 is tilted in the M direction. The device 1 operates in the m direction. On the other hand, when the bedside operation panel 15 is mounted on the right side R in the longitudinal direction of the bed 4, that is, at the position indicated by the broken line in FIG. It operates in the n direction. Thereby, even when the operator operates the bedside operation panel 15 indicated by the broken line on the right side R in the longitudinal direction of the bed part 4, the operation direction M of the operation lever 91 and the operation direction n of the apparatus 1 match. The operator can operate the device 1 intuitively.

  According to the device 1 according to the third embodiment, a plurality of paths that connect the wireless communication unit C33 and the wireless communication unit H81 or I83 in a one-to-one relationship are provided, so that wireless communication attached to one path, for example, the R side. Even when the apparatus 1 is arranged on the path connecting the part C33 and the wireless communication part H81 and the main control part 11 cannot receive the operation signal, the wireless communication part C33 attached to the other path, for example, the L side, and the wireless communication If the device 1 is not disposed on the path connecting the unit I81, the main control unit 11 can receive the operation signal. Therefore, when there are a plurality of paths that connect the wireless communication unit C33 and the wireless communication units H81 and I83 in a one-to-one relationship, the main control unit 11 is connected to the main control unit 11 via the wireless communication units H81 and I83. It can be seen whether the operation signal to be received is output from the bedside operation panel 15 on the R side or L side of the bed 4.

  According to the apparatus 1 according to the third embodiment, the attachment side determination units J85 and K87 receive the operation signal wirelessly transmitted from the wireless communication unit C33 to the wireless communication units H81 and I83, so that the bedside operation panel 15 becomes the bed. It is determined which of the 4 R side and L side is attached. The movement direction changing unit 89 changes the movement direction of the movement lever 82 of the bedside operation panel 15 when the determined attachment side is different from the reference attachment side. Thereby, for example, when the bedside operation panel 15 is for operating the apparatus 1 with reference to the mounting position on the L side of the top plate, the mounting position of the bedside operation panel 15 is on the R side of the top panel. When changed, an operation signal is sent from the path connecting the wireless communication unit C33 provided on the bedside operation panel 15 mounted on the R side of the top plate to the attachment side determination unit J85 to the attachment side determination unit J85. Therefore, the attachment side determination unit J85 can determine that the bedside operation panel 15 is attached to the R side of the top plate length based on the received operation signal. Since the attachment side to be determined is the R side, and the reference attachment side is the L side, they are different. In this case, since the operation direction changing unit 89 changes the operation direction of the operation lever 82 provided on the bedside operation panel 15 to the left and right, when the bedside operation panel 15 is operated in the M direction, the apparatus 1 operates in the n direction. . As a result, the operator can easily understand the operation direction of the bedside operation panel 15.
