Fig. 2 is a schematic view of a slip ring device according to an embodiment of the present invention. As shown in fig. 2, the present embodiment provides a slip ring device applied to a medical imaging system, and the slip ring device includes a slip ring power transmission module 40 and a power line carrier module 20, and these two modules are described in detail below. It should be noted that the slip ring device of the present embodiment may be applied not only to a CT system, but also to other medical imaging systems powered by a slip ring, such as an RT radiotherapy system.
Regarding the slip ring power transmission module 40, the slip ring power transmission module 40 may form at least one power transmission line (power transmission slideway), and the power transmission line may obtain the power provided by the power supply module 70 through its first power transmission end a and then output to the load 60 through its second power transmission end B to supply power to the load 60, where the load 60 includes, but is not limited to, a bulb 11, a detector 12, a collimator, a high voltage circuit, a switching power supply, and a heat dissipation module in a CT system. It should be noted that, the power transmission line herein specifically refers to a power transmission slideway in the slip ring power transmission module 40 and a power line 30 (which is exemplified by a thickened line in fig. 1) connected at two ends, and may be used to transmit a 220V voltage to supply power to the load 60. Regarding the formation of the power transmission path of the slip ring power transmission module 40, conventionally, the slip ring power transmission module 40 includes a slip ring and a brush, one of which is provided on the rotating portion 82 of the scanner frame 80, the other of which is provided on the fixed portion 81, relative rotation of the rotating portion 82 and the fixed portion 81 being such that the slip ring and the brush are in sliding contact, thereby forming a power transmission path between the slip ring and the brush, one of the brush and the slip ring provided on the fixed portion 81 being connected to the power supply module 70 through the power line 30, and the other of the brush and the slip ring provided on the rotating portion 82 being connected to the load 60 through the power line 30, whereby the power transmission path formed by the brush and the slip ring and the power lines 30 on both sides collectively form the power transmission line.
Regarding the power line carrier module 20, the power line carrier module 20 of the present embodiment is configured based on the power line 30 carrier (Power Line Communication, PLC) technology, which uses the power line 30 as a carrier and enables high-speed transmission of analog signals or digital signals by carrier, and is widely used in power systems due to advantages such as long communication distance, low cost, high reliability, and isochrony. In this embodiment, the first power transmission end a and the second power transmission end B are both provided with the power line carrier module 20, so that the power line carrier module 20 adjusts the frequency of the data signal, so that the data signal is transmitted from the second power transmission end B to the main control module 50 located at the first power transmission end a through the power transmission line, and the main control module 50 includes at least one of the console 51 and the image reconstruction unit 52. For example, the data signal includes a medical image data signal, the bulb 11 and the detector 12 in the image acquisition module 10 cooperate to provide the medical image data signal about the scanner 90, and then the frequency of the medical image data signal is adjusted by the power line carrier module 20 located at the second power transmission end B, so that the medical image data signal is transmitted to the power line, and then the frequency of the medical image data signal is adjusted by the power line carrier module 20 located at the first power transmission end a, so that the medical image data signal can be transmitted to the image reconstruction unit 52 of the main control module 50, so that the medical image is reconstructed according to the reconstruction algorithm, and it can be understood that the transmission of the medical image data signal is unidirectional, that is, the image acquisition module 10 is unidirectionally transmitted to the image reconstruction unit 52 by the power line of the slip ring power transmission module 40. Therefore, the medical image signal data is processed through the PLC technology, the processed medical image signal data is transmitted through the power transmission line, and therefore an independent transmission line is not required to be allocated to the medical image signal data, the line design of the slip ring for transmitting the medical image signal data can be simplified or abandoned, the structural design of the slip ring is simplified, and the design cost is reduced.
Further, the data signals further include control data signals, so that the control data signals provided by the image acquisition module 10 can be transmitted to the console 51 of the main control module 50 through the transmission line of the slip ring transmission channel. The control data signal provided by the image acquisition module 10 may reflect to the console 51 the current operating state of the image acquisition module 10, such as what stage the paying-off operation of the bulb 11 is in (start of paying-off, in-process of paying-off, or completion of paying-off).
Preferably, the control data signal may be transmitted in two directions between the image acquisition module 10 and the console 51 through the power transmission line of the slip ring power transmission channel, and specifically, the power line carrier module 20 adjusts the frequency of the control data signal, so that the control data signal may be communicated in two directions between the main control module 50 and the image acquisition module 10 located on the second power transmission end B through the power transmission line. The control data signals provided by the console 51 are used to control the operational state of the image acquisition module 10, such as when the bulb 11 pays out and when it breaks the payoff, adjust the dose parameters of the payoff, control when the image acquisition module 10 transmits medical image data signals outwards, etc. Therefore, the transmission line can also transmit the control data signal, and an additional transmission line is not required to be provided for the control data signal, so that the design is simplified.
Fig. 3 is another schematic view of a slip ring device according to an embodiment of the present invention. Referring to fig. 3, slip ring power transmission module 40 may form at least two power transmission lines, one for transmitting the power and the other for transmitting medical image data signals and/or control data signals. By way of example, fig. 3 illustrates two transmission lines, one of which is indicated by a bold dashed line for transmitting power of the power supply module 70 and the other of which is indicated by a bold solid line for transmitting data signals, such as medical image signal data, control data signals, and of course medical image data signals and control data signals, simultaneously. Of course, three independent transmission lines may be allocated in this embodiment, for transmitting power, medical image data signals and control data signals, respectively. Preferably, the same transmission line may transmit at least two of the power, the medical image data signal and the control data signal simultaneously.
With continued reference to fig. 2 and 3, regarding the structural configuration of the power line carrier module 20, the power line carrier module 20 at the second power transmission end B at least includes a modulator 21, and the modulator 21 is configured to receive the data signal and then modulate the data signal to change the frequency of the data signal; the power line carrier module 20 at the first power transmission end a at least includes a demodulator 23, where the demodulator 23 is configured to receive the data signal modulated by the modulator 21 and demodulate the data signal to restore the frequency of the data signal.

In general, in the process of transmitting data signals on the slip ring based on the power line carrier technology Power Line Communication, PLC), the power transmission line is easily interfered by electromagnetic environment, so that error codes and packet loss occur in the process of transmitting signals, and the transmission rate of the signals is unstable and is low. In addition, the power transmission line is connected to various loads 60, in the CT system, the loads 60 may be a bulb tube and a high-voltage system in the CT, or may be various switching power supplies, heat dissipation modules, etc., and these loads 60 have different noise characteristics, and noise may be conducted to the power transmission line, so as to exacerbate interference in the signal transmission process. In addition, the power supply end of the CT (such as the power supply module 70) may introduce various noises on the power grid and further transmit to the power line, thus also affecting the signal transmission. The signal anti-interference module is configured in the embodiment, so that interference signals on a power transmission line, such as electromagnetic interference signals and power grid noise, can be removed, the influence of external interference signals on data signals in the transmission process can be avoided as much as possible, the transmission rate of the data signals is improved, and the transmission stability of the data signals is improved.

Further, the signal anti-interference module further includes a grounding unit 112, and the electromagnetic shielding unit is connected to at least one grounding unit 112, so as to drain the interference signal into the ground. For example, a grounding unit 112 may be connected to the electromagnetic shielding unit at the position of the first power transmission end a and the position of the second power transmission end B, respectively.
