Embodiment Construction

[0015] The positioning method for magnetic resonance of the present invention includes:

[0016] a. There is a human-computer interaction device in the form of a touch screen in the scanning room of the magnetic resonance equipment, and a schematic diagram of a human body model and a scanning coil is displayed on the human-computer interaction device;

[0017] b. After the patient is on the sickbed in the magnetic resonance cavity, turn on the laser light to emit a positioning beam, use the middle area of ​​the quasi-scanning coil to position the positioning beam, and use the laser beam to position the scanning part and the touch screen form The operation of the human-computer interaction device can determine the position of the positioned area in the scanning coordinate system;

[0018] c. Select the part that the patient needs to scan on the human-computer interaction device. If the patient needs to scan at least two parts, select the parts that need to be scanned in turn; ...

Abstract

The invention relates to a positioning method for magnetic resonance. The method comprises the following steps: a, displaying a schematic diagram with a human body model and a scanning coil on visible human-machine interactive equipment which is arranged in a magnetic resonance equipment scanning room; b, starting a positioning beam after a patient lies on a bed in a magnetic resonance cavity, and positioning the positioning beam according to the position of the scanning coil; c, selecting the part to be scanned of the patient on the human-machine interactive equipment; d, moving the bed until the selected scanning part displayed on the human-machine interactive equipment is positioned under the positioning beam. The positioning method can be used for effectively positioning coils for performing combined scanning on the belly or great vessels and the like, so that coordinate information of unfixed important coil units can be acquired, and an operator can carry out positioning operation without repeatedly entering the scanning room. Therefore, the scanning efficiency is greatly improved, and the cost on scanning time of coil positioning in a pre-scanning mode can be eliminated.

Description

technical field [0001] The invention relates to a positioning method for magnetic resonance, in particular to a positioning method for a non-fixed coil requiring combined scanning of two scanning coils. Background technique [0002] With the development of magnetic resonance technology and the maturity of radio frequency surface coil array technology, in clinical application, in addition to the conventional scan of a single site, the joint scan of multiple scan coils has increasingly become a part of magnetic resonance imaging. a trend. If a large-scale joint scan or even a whole-body scan of a moving hospital bed is to be realized, it is necessary to accurately determine the position information of the magnetic resonance coil antenna unit used under the scan coordinates. The existing coil positioning scheme can input the position information of fixed coils (such as spine coils and head and neck coils) and antenna distribution units into the system software, which can be co...
