In this embodiment, the handheld mobile device 1 may be a tablet computer, a notebook computer, a mobile phone, or the like, so long as an expert can conveniently hold the device at a remote end, and display an image of the remote medical image device 2 through the display device, and input own operation of the medical image device 2 through the input device. The medical imaging device 2 may be a computed tomography device CT, a magnetic resonance imaging device MR, an angiography device, a molecular imaging device, an ultrasound device, an X-ray machine, or the like, as long as the medical image of the object to be detected can be acquired. The first conversion device 3 is important, and is connected to the medical imaging device 2, and this connection may be plugged into an input/output (I/O) interface of the medical imaging device 2, or may be a wireless communication connection, which is not limited herein. The first conversion device 3 comprises first video codec means 31 which can compress the medical image acquired by the medical imaging device 2 and transmit it out via second communication means 32. The compression algorithm for video uses known techniques, as long as the compression algorithm is suitable for the network bandwidth. The first communication means 12 and the second communication means 32 communicate via a first type of wireless network and transmit the compressed medical image to the handheld mobile device 1 for viewing by an expert at a remote location. In this embodiment, the image acquired by the medical image device 2 is compressed in the first conversion device 3, so that the format of the medical image can be conveniently converted into a format suitable for the first type of wireless network transmission without changing the medical image device, and the format is sent to the handheld mobile device 1 of the expert. The embodiment is convenient for remote teaching and guidance, and the expert can be at any position, so that the efficiency is improved.

In an exemplary embodiment, referring specifically to fig. 2 and fig. 4, the medical imaging device remote control system further includes a second conversion device 4, including a second video codec device 41, a third communication device 42, and a fourth communication device 43, where the third communication device 42 and the second communication device 32 communicate through a first type wireless network, and the fourth communication device 43 and the first communication device 12 communicate through a second type wireless network. The handheld mobile device 1 used by the remote expert may not support the video compression decompression algorithm of the first video codec 31 or may not install a special program to support such an algorithm. In this case, the embodiment provides the second conversion device 4 comprising second video codec means 41 for decoding the video signal received by the third communication device 42 and transmitting the data to the handheld mobile device 1 via the second type wireless network using fourth communication means 43. Here, the first type of wireless network may be a mobile communication network, such as a 5G public network. The 5G network is used, so that a special network is avoided being erected, and the arrangement is convenient. The second type of wireless network may be a wireless local area network, which may be disposed in a hospital or in a home, so that a remote expert may conveniently receive data in his own hospital or in the home by using the handheld mobile device 1. The second conversion device 4 is provided to be convenient for two scenarios, the first scenario is that the handheld mobile device 1 does not support the video compression algorithm of the first video codec 31, at this time, the second video codec 41 adapted to the first video codec 31 is used to decode the video signal of the medical image first, and then the video signal is transmitted in the format supported by the handheld mobile device 1. The second scenario is that the expert does not install a special program in the handheld mobile device 1, but operates with a way such as to access a specific web site, which is particularly useful for the expert, who can access a specific web site using any handheld device to access a remote control interface when the second switching device 4 is arranged in a hospital. The second conversion device has a smaller size, so that the expert can conveniently move the second conversion device, for example, to home or to classroom, that is, any computing device can be used to access the medical imaging device remote control system by accessing the second conversion device as long as the second conversion device 4 is carried.

In an exemplary embodiment, referring in particular to fig. 3, the handheld mobile device 1 further comprises a power supply assembly 13 for powering said handheld mobile device 1; a camera assembly 14 for acquiring image and/or video information; a microphone assembly 15 for acquiring audio information. The far-end expert needs to train the doctor or personnel at the near-end where the medical imaging device 2 is located, so the camera component 14 and the microphone component 15 are arranged on the handheld mobile device 1 and are used for collecting the audio and video information of the expert, so that the near-end where the medical imaging device 2 is located has face-to-face communication. The expert at the far end needs not only to watch the video information but also to have the operation requirement, so that the touch screen assembly 11 is suitable, and the touch screen assembly 11 is used as a display device and an input device at the same time, so that the size of the equipment can be reduced to the greatest extent.

In an exemplary embodiment, referring in particular to fig. 3, the handheld mobile device 1 further comprises switching means 16 for switching the first communication means 12 between a first communication state in which the first communication means 12 and said second communication means 32 communicate, wherein the handheld mobile device 1 is in direct communication with the first switching device 3 via the first type of wireless network, and a second communication state in which the first communication means 12 and the fourth communication means 43 communicate, wherein the finger mobile device 1 is in communication with the first switching device 3 via the second switching device 4. The provision of the switching means 16 allows the handheld mobile device 1 to operate in two ways, one directly using the public network, e.g. the 5G network, and the first switching device 3 at the near end for information transfer, and the other for transfer via the second switching device 4. Both modes of operation are each used in specific situations. For example, the two operating modes may be set with different rights by using known techniques, in the first operating mode, the remote expert may only view the image acquired by the medical imaging device 2 and cannot operate the remote medical imaging device 2 by the handheld device, because the connection directly through the public network has a security problem at this time, and in the second operating mode, the handheld mobile device 1 may be given higher rights, for example, the remote expert may directly use the input device to control the medical imaging device 2, for example, to input parameters or start acquisition. Because in the second mode of operation the first conversion device 3 and the second conversion device 4 can be conveniently encrypted.

In an exemplary embodiment, referring specifically to fig. 4, the second conversion device 4 further comprises mouse-to-keyboard signal conversion means 44 for converting a touch screen signal of the input means into a mouse-to-keyboard signal. The mouse-to-keyboard signal conversion device may be implemented using known techniques, such as ipKVM. The expert at the far end has the requirement of directly controlling the medical imaging device 2 at the near end, when the expert inputs by using the touch screen assembly 11, the medical imaging device 2 at the near end cannot directly recognize the touch input operations, and the touch signal of the touch screen assembly 11 is converted into the mouse keyboard signal by using the mouse keyboard signal conversion device 44, so that the medical imaging device 2 can directly recognize the signal without modification.

In an exemplary embodiment, referring specifically to fig. 4, the medical image device remote control system further includes an audio/video capturing and playing system 5, where the audio/video capturing and playing system 5 is connected to the first conversion device 3, and the first role of the audio/video capturing and playing system 5 is to capture an audio/video image of an area to be captured, i.e. an area where an object to be inspected, such as a patient, is located, and transmit the audio/video image to a far-end expert, so that the audio/video capturing and playing system 5 includes a first audio capturing device 51 for capturing audio information of the area to be captured by the medical image device 2, and a first video capturing device 53 for capturing video information of the area to be captured by the medical image device 2, and by capturing the audio/video of the object to be inspected, the remote expert may guide the position or posture of the object to be inspected, and the sound of the object to be inspected may also transmit the sound of the object to the expert for reference by the expert. In addition, the information of the control area of the medical image device 2 also needs to be known to the expert, and the doctor at the near end needs to communicate with the expert at the far end, so the audio/video capturing and playing system 5 further includes a second audio capturing device 52 for capturing the audio information of the control area of the medical image device 2. The doctor in the control area and the remote expert need to carry out voice communication, and even more, the video information in the control area needs to be collected, so that the face-to-face communication effect is achieved. In addition, the audio/video capturing and playing system 5 further includes a first audio player 54 for playing audio information in a region to be captured of the medical imaging device 2, a second audio player 55 for playing audio information in a control region of the medical imaging device 2, and a first video player 56 for playing video information in the control region of the medical imaging device 2, so that a doctor operator of an inspected object and the control region in the region to be captured can hear the sound instruction of an expert, and the operator can also see the image of the expert to communicate face to face.

In one exemplary embodiment, referring specifically to fig. 1-4, the exemplary embodiment employs a high-performance portable mobile tablet device as the handheld mobile device 1 and a 5G network as the first type of wireless network for signal transmission. More specifically, on the mobile tablet device, a WeChat expert login authentication is integrated.
