Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and particularly relates to a medical CT slip ring system adopting wireless communication technology. Background Art

[0002] In recent years, computed tomography imaging technology (CT machine) has been widely applied in the fields of medical treatment and safety inspection. The slip ring of the CT machine is one of the core components of the CT. One of the functions of the CT slip ring is to transmit the power supply required by the rotating X-ray tube and other rotating components. In addition, it is necessary to transmit the image data from the rotating X-ray detector array to the fixed data processing computer. These transmission tasks are completed by using slip rings, that is, sliding electrical contacts. Each loop needs to be connected to a carbonaceous or other type of brush. With the continuous improvement of the requirements for data speed and cost reduction in the development of medical CT, a slip ring system that reduces costs while ensuring transmission performance is needed.

[0003] At present, the physical and electrical connection from the fixed end to the rotating end of the CT device is mainly carried out through slip rings. The high-voltage power supply required by the rotating end components is provided through the power loop of the slip ring, and the low-voltage level signals are transmitted through the signal loop of the slip ring, enabling command and status communication and interaction between the fixed end and the rotating end. Such communication signals generally adopt the general industrial CAN or RS422 communication protocol; the image data is unidirectionally transmitted and received in a radio frequency manner through the capacitive antenna of the slip ring data loop; some CT systems also transmit the encoder pulse signals of the rotation angle position through the slip ring loop. These power supplies and electrical signals increase the number of contact loops of the slip ring, and also increase the consumption of slip ring carbon brush consumables, increasing costs and unreliability.
