[0024] In the subsequent description, the suffix such as "module", "component" or "unit" used to represent elements is only for the convenience of the description of the present application, and has no specific meaning in itself. Therefore, "module" and "component" can be used interchangeably.

[0025] Referring to the accompanying drawings Figure 1 The present application discloses an accessory identification device of a scanning bed, the scanning bed comprising a bed body and a support frame, the bed body being arranged on the support frame. The lifting of the support frame drives the lifting of the bed body, and the bed body can also move axially on the support frame, which can also be understood as moving forward and backward compared with the CT device.

[0026] The CT scanning bed can be equipped with some accessories to provide better patient support, comfort and operational convenience. For example, phantom, headrest, extension plate, etc.

[0027] The bed body is provided with a plurality of sensing slots, and each sensing slot is provided with a sensor for sensing the accessories, specifically for sensing the sensing coil on the accessories.

[0028] The position of the inductive coil of the accessory corresponds to one or more of the inductive slots (inductors) so that the inductive coil on the accessory can be accurately captured by the inductors on the bed body, so that the bed body can know that the accessory is arranged. Moreover, the position and number of inductive coils of different accessories are different, and by combining different positions and numbers, each different accessory can be distinguished. Specifically, when the accessory is arranged on the bed body, the coil on the accessory produces an inductive connection with the inductor on the scanning bed; when different accessories are arranged on the bed body, an inductive connection is produced with inductors of different positions and numbers on the bed body.

[0029] The controller is further included, which is connected with the inductors and used to receive inductive signals of the inductors and generate different control signals through the inductive signals of inductors of different positions and numbers, and control the bed body according to the control signals.

[0030] The connection of the controller can be wired connection, but more preferably wireless connection, for example, the controller is arranged on the CT device console, which is generally arranged outside the CT room, so that the operator can accurately guide the scanning bed to arrange which accessory outside the CT room, thereby more accurately controlling the scanning bed. More preferably, when the controller identifies the current accessory according to the position and number of inductive coils on the accessory, the bed body can be automatically controlled.

[0031] Preferably, the accessory is arranged on the bed body through the connecting piece, which is usually inserted in the form of a plug, the accessory is first connected with the connecting piece, and then the connecting piece is inserted into the specified position of the bed body, so that the accessory can be fixed on the bed body. In this case of using the connecting piece, the inductive coil on the accessory is more preferably arranged on the connecting piece. The connecting piece can usually use a link plate.

[0032] Preferably, the inductive slots on the bed body are arranged at one end of the bed body, as shown in Figure 1 The inductive slots are arranged in the axial direction, and the inductors on the accessory are also arranged in the axial direction and correspond to the positions of the inductive slots on the bed body when inserted into the bed body, so that the inductors on the bed body can accurately induct the inductive coil on the accessory.

[0033] Preferably, the number of inductive coils on the accessory is less than or equal to the number of inductors, so as to ensure that the inductive coil can be captured by the inductor on the bed body, and different accessories are captured by inductors of different positions and / or numbers.

[0034] The inductive groove position on the bed body is fixed at the time of product delivery and cannot be changed later, so the number of inductive groove positions can be set to be larger. Usually, the number of inductors is equal to the number of inductive groove positions to realize more combinations of different positions and numbers, so as to identify more accessories. However, in the case of fewer accessories, the number of inductors can be set to be smaller than the number of inductive groove positions to support the identification of a smaller number of accessories. On this basis, if the number of accessories to be identified increases, the number of sensors in the reserved inductive groove position can be increased to realize more combinations of different numbers and positions, so as to identify more different accessories.

[0035] In a preferred example, referring to the accompanying drawings Figure 1 The number of inductive groove positions on the bed body is 3, the number of inductors is 3, and the number of inductive coils on the accessory is at most 3, so that the inductive coil on the accessory can correspond to a first inductive groove position setting, can correspond to a second inductive groove position setting, can correspond to a third inductive groove position setting, can correspond to a first inductive groove position and a second inductive groove position setting, can correspond to a third inductive groove position and a second inductive groove position setting, can correspond to a first inductive groove position and a third inductive groove position setting, and can also correspond to a first inductive groove position, a second inductive groove position and a third inductive groove position setting, so as to identify 7 different accessories.

[0036] The application also discloses an accessory identification method of a scanning bed, based on the accessory identification device of the scanning bed, comprising the following steps:

[0037] Different accessories are arranged on the bed body, so that the coil on the accessory is inductively connected with the inductors of different positions and numbers on the bed body.

[0038] The controller is connected with the inductors to receive the inductive signals of the inductors, and different control signals are generated through the inductive signals of the inductors of different positions and numbers, and the bed body is controlled according to the control signals.

[0039] In a preferred example, the number of inductive groove positions on the bed body is 3, the number of inductors is 3, and the number of inductive coils on the accessory is at most 3.

[0040] The inductive coil of the accessory corresponds to a first inductive groove position setting and is inductively connected with a first inductor on the bed body to send a first type of inductive signal to the controller.

[0041] The inductive coil of the accessory corresponds to a first inductive groove position setting and is inductively connected with a second inductor on the bed body to send a second type of inductive signal to the controller.

[0042] The inductive coil of the accessory corresponds to the first inductive slot, and is in inductive connection with the third inductor on the bed body to send a third type of inductive signal to the controller;

[0043] The inductive coil of the accessory corresponds to the first inductive slot and the second inductive slot, and is in inductive connection with the first inductor and the second inductor on the bed body to send a fourth type of inductive signal to the controller;

[0044] The inductive coil of the accessory corresponds to the first inductive slot and the third inductive slot, and is in inductive connection with the first inductor and the third inductor on the bed body to send a fifth type of inductive signal to the controller;

[0045] The inductive coil of the accessory corresponds to the third inductive slot and the second inductive slot, and is in inductive connection with the third inductor and the second inductor on the bed body to send a sixth type of inductive signal to the controller;

[0046] The inductive coil of the accessory corresponds to the first inductive slot, the second inductive slot and the third inductive slot, and is in inductive connection with the first inductor, the second inductor and the third inductor on the bed body to send a seventh type of inductive signal to the controller.

[0047] The controller generates different control signals according to different inductive signals, and in the above preferred example, seven different control signals can be generated to control seven different accessories.

[0048] The controller controls the bed body according to the control signals, including but not limited to controlling the lifting, stroke, limit, running speed and position of the bed body, to prevent the movement of the scanning bed from being interfered after setting the accessories. For example, when the accessory matched with the scanning bed is an extension plate, the controller matches the corresponding motion control firmware to limit the lifting and forward position of the scanning bed to prevent the scanning bed with the extension plate from colliding with the gantry.

[0049] In order to ensure the safety of automatic control, the controller generates different control signals according to different inductive signals, and then needs to be confirmed by the operator before executing the control signal. Specifically, when the controller generates different control signals through different positions and quantities of inductive signals, if an external confirmation instruction is received within a preset time period, the bed body is controlled according to the control signal. If no external confirmation instruction is received, the bed body is abandoned.

[0050] It should be noted that the embodiments of the present application have better implementation, and do not limit the present application in any form, any skilled person in the art can change or modify the above disclosed technical content into equivalent effective embodiments, as long as it does not deviate from the content of the technical scheme of the present application, any modification or equivalent change and modification of the above embodiments according to the technical essence of the present application, still belongs to the scope of the technical scheme of the present application.
