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
The present invention relates to the localization method for magnetic resonance, is the localization method for two scanning coil array sweepings of needs of free-standing coil concretely.
Background technology
Along with the development of mr techniques, and the reaching its maturity of radio frequency surface coils array technology, in clinical practice, except the conventional sweep at single position, the scanning coil Combisweep at a plurality of positions has more and more become a kind of trend of nuclear magnetic resonance.If realize the even body scan of Mobile sickbed of large-scale Combisweep, just need the accurate positional information of magnetic resonance coil antenna element used under scanning coordinate of determining.Existing coil location scheme can, by the positional information of fixed coil (as vertebra coil and head and neck coil) and antenna distribution unit input system software, can show easily in scanning coordinate.But for those free-standing coils, such as abdominal part coil and lower limb vascular coil etc. has the coil of undefined position, these coils situation according to different patients in actual use has changeable position, relatively is difficult to determine the relative coordinate of coil unit.Some people has taked, by the measure to the abdominal part prescan, to come the position of judging unit by the post processing of image at present.But this method needs more complicated software support and prescan to cause increase sweep time.
Summary of the invention
For above-mentioned problem, the invention provides a kind of localization method for magnetic resonance, can locate accurately fast the locus of free-standing coil, optimize scanning process, make patient's body scan and the automatization of coil unit select to have possibility.
The present invention, for the localization method of magnetic resonance, comprising:
A. the scanning room at magnetic resonance equipment is provided with visual human-computer interaction device, shows the schematic diagram of anthropometric dummy and scanning coil on the human-computer interaction device; Magnetic resonance equipment mainly divides three zones, and the firstth, the main place system rack of equipment room, scanning room namely, between magnet, comprises the scanning areas such as magnet sick bed, also has operating space, is mainly to place main frame and displayed map picture;
B. after patient is positioned on the sick bed of magnetic resonance cavity, open aligned bundle, position with aligned bundle according to the position of scanning coil;
C. select the position of client need scanning on the human-computer interaction device;
D. move described sick bed, until the scanning position of described selection is positioned at the aligned bundle below.
Further, when at least two positions of client need scanning, need successively to scan the selection at position in step c, magnetic resonance system is scanned successively according to the position of selecting and the installation site of scanning coil when scanning.
Preferably, in step b, by the central region by aligned bundle alignment scanning coil, aligned bundle is positioned.The central region of scanning coil of take can effectively be simplified the complexity of subsequent operation as the centre of location, improves the convenience degree of operation.Also can position other position with scanning coil according to different situations.
Concrete, by laser beam, the scanning position is positioned with described visual human-computer interaction device's operation and determines the position of zone under scan coordinate system that be positioned.
Concrete, described human-computer interaction device is touch screen.
The present invention is for the localization method of magnetic resonance, can be effectively abdominal part or trunk etc. be carried out to coil location for the coil of array sweeping, thereby realized obtaining the coordinate information of these revocable important coil units, the operator positions operation without repeatedly entering scanning room, save greatly scan efficiency, also avoided being undertaken by the mode of prescan expense sweep time of coil location.
Below in conjunction with the specific embodiment of embodiment, foregoing of the present invention is described in further detail again.But this should be interpreted as to the scope of the above-mentioned theme of the present invention only limits to following example.Without departing from the idea case in the present invention described above, various replacements or the change according to ordinary skill knowledge and customary means, made, all should comprise within the scope of the invention.
The specific embodiment
Localization method for magnetic resonance of the present invention comprises:
A. be provided with the human-computer interaction device of touch screen form at the scanning room of magnetic resonance equipment, show the schematic diagram of anthropometric dummy and scanning coil on the human-computer interaction device;
B. after patient is positioned on the sick bed of magnetic resonance cavity, open laser lamp and send aligned bundle, aligned bundle is positioned aligned bundle by the central region of accurate scanning coil, by laser beam, the scanning position is positioned with the human-computer interaction device's of described touch screen form operation and just can determine the position of zone under scan coordinate system that be positioned;
C. select the position of client need scanning on the human-computer interaction device, if when client need scans at least two positions, select to need successively the position of scanning;
D. move described sick bed, until show that the scanning position of described selection is positioned at the aligned bundle below, magnetic resonance system is scanned successively according to the position of selecting and the installation site of scanning coil when scanning.
Thus can be effectively abdominal part or trunk etc. be carried out to coil location for the coil of array sweeping, thereby realized obtaining the coordinate information of these revocable important coil units, the operator positions operation without repeatedly entering scanning room, save greatly scan efficiency, also avoided being undertaken by the mode of prescan expense sweep time of coil location.
