Embodiment 1
[0041] In this embodiment, the medical imaging system selects the magnetic resonance system, the signal generator is an ultrasonic (signal) transmitter, and the signal receiver selects an ultrasonic probe.
[0042] Figure 1a It is a structural block diagram of the magnetic resonance system in Embodiment 1 of the present invention. This embodiment is applicable to the situation of positioning between the target area to be scanned of the subject and the hospital bed in magnetic resonance imaging. Such as Figure 1aAs shown, the magnetic resonance system 100 specifically includes: a scanner 110 , a controller 120 , a memory 130 , a display 140 and a connection network 150 . The scanner 110 may include a magnet module and a radio frequency (RF) module. The magnet module may include magnets and / or gradient magnetic field generators. The magnet can generate a static magnetic field B0 during an MRI procedure. The magnets can be of various types including, for example, permanent ma...
Embodiment 2
[0059] figure 2 It is a flow chart of the positioning method of the medical imaging system provided by the second embodiment of the present invention. The medical imaging system includes: a scanner, forming a scanning cavity, the scanning cavity has a main longitudinal axis of a proximal end and a distal end, the proximal end of the main longitudinal axis is the end face of the scanning cavity close to the doctor, and the far end of the main longitudinal axis is the opposite side of the proximal end The end face, the center of the main longitudinal axis corresponds to the center of the scanning cavity, and the FOV area is formed at this position; the hospital bed, which can move in the scanning cavity; the signal generator, which can be placed above the patient bed; multiple signal receivers, distributed in the On the above-mentioned scanner, specifically, it can be arranged on the end face corresponding to the near end of the scanner. The positioning method of the above-men...
Embodiment 3
[0066] image 3 It is a flow chart of the positioning method of the medical imaging system provided by Embodiment 3 of the present invention. This method can be realized by the magnetic resonance system in the above embodiment, such as image 3 As shown, the positioning method of the magnetic resonance system specifically includes the following steps:
[0067] S310. Place the ultrasonic signal generator in a first vertical plane corresponding to the subject's target area, and use the ultrasonic signal generator to transmit an ultrasonic signal or a detection signal.
[0068] Specifically, during the examination process of the magnetic resonance imaging, the subject should lie on a movable hospital bed and be fixed in a supine position or a prone position. The doctor holds the remote controller and stands beside the hospital bed, and places the remote controller, that is, the ultrasound signal generator, in the first vertical plane corresponding to the subject's target area to...
