Problems solved by technology
However, the device where the hand detection coil is located is usually a closed structure, and it is impossible to check the specific position of the hand
like figure 2 and image 3 As shown, when the position of the hand is not ideal (the hand is ahead or the hand is behind), it will have a bad influence on the scanned results, and it will also cause unnecessary repetitive scanning

The invention relates to a coil positioning device which comprises a coil device, a marker, detection devices and a control unit. The marker is arranged on a to-be-detected object, the detection devices are positioned in the coil device and used for detecting the marker and generating detection signals, and the control unit is connected with the detection devices to receive the detection signals generated by the detection devices and judge the position of the to-be-detected object corresponding to the marker according to the detection signals. The marker is adopted to mark the position of the to-be-detected object, the position of the marker is determined by the detection devices, and the to-be-detected object marked by the marker is adjusted to a proper position in a coil unit of a magnetic resonance instrument for nuclear magnetic resonance detection, so that pre-scanning work and repeated scanning operations for determining the position of the to-be-detected object are omitted, and coil utilization rate is increased.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a coil positioning device. Background technique [0002] Existing magnetic resonance equipment has various coil devices, such as hand coils, knee coils, and neck coils. However, there is no positioning device in the magnetic resonance equipment. In the hand coils, the doctor or patient places the position of the hand by feeling. position, and then perform a pre-scan (localizer) to determine the position of the hand, and correct the position of the hand according to the results of the pre-scan, resulting in unnecessary repetitive scans. [0003] Let's give an example to illustrate, take hand detection as an example, such as figure 1 As shown, the first coil unit 21, the second coil unit 22, and the third coil unit 23 respectively represent the coils corresponding to the palm fingers, wrist joints, and arms of the hand 4. Due to factors such as cost, equipment complexity, and system...
