Description
Technical field
The present invention relates to the intelligent selecting method of the magnetic resonance line coil unit for whole body imaging.
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 coil Combisweep at multiple positions has increasingly becomed a kind of trend of nuclear magnetic resonance.In existing patent and pertinent literature, having been disclosed for how being accurately positioned the position of coil unit, to solve at present is exactly the problem automatically selected of scanning coil unit.In existing magnetic resonance applications, the selection of scanning coil unit is usually and manually operates, and when coil is combined scanning time, carrying out manually selecting scanning coil unit can be more complicated, bring very loaded down with trivial details and thorny sensation to operator.
Summary of the invention
For above-mentioned problem, the invention provides the intelligent selecting method of a kind of magnetic resonance line coil unit for whole body imaging, it is possible under the pinpoint premise of scanning coil unit, the scanning coil unit in areas imaging is carried out intelligentized selection.
The present invention is used for the intelligent selecting method of the magnetic resonance line coil unit of whole body imaging, including:
A. patient enters magnetic resonance imaging cavity, and the position scanned as required is to after each scanning coil cell location, it is determined that the imaging region of scanning and the scanning coil element number in described imaging region；
B., within the scope of the imaging region of described scanning, software system is to automatically select described each scanning coil unit from the center of imaging region to the direction at imaging region edge, and the correspondence position of imaging region is scanned by the scanning coil unit chosen.
Further, the quantity of the scanning coil unit of described selection is less than or equal to the overall channel number of system.If the scanning coil number of unit of system is not one_to_one corresponding (namely having carried out the situation that scanning coil cell signal merges) with passage, do not consider herein.
Preferably, if only the scanning coil unit of some quantity is in imaging region, the scanning coil unit entering imaging region is pointed out, and carried out manually supplementing selecting scanning coil unit according to actual scanning by user.
Same, when user manually selects, the quantity of selected scanning coil unit, less than or equal to the overall channel number of system, if the scanning coil number of unit of system is not one_to_one corresponding (namely having carried out the situation that scanning coil cell signal merges) with passage, is not considered herein too.
The present invention is for the intelligent selecting method of the magnetic resonance line coil unit of whole body imaging, can under the pinpoint premise of scanning coil unit, scanning coil unit in areas imaging is carried out intelligentized selection, significantly simplify scan operation, and save sweep time, the operating experience of user has been greatly improved.
Below in conjunction with the detailed description of the invention of embodiment, the foregoing of the present invention is described in further detail again.But this should not being interpreted as, the scope of the above-mentioned theme of the present invention is only limitted to Examples below.Without departing from the idea case in the present invention described above, the various replacements made according to ordinary skill knowledge and customary means or change, all should be included within the scope of the invention.
Detailed description of the invention
The intelligent selecting method of the magnetic resonance line coil unit for whole body imaging of the present invention, including:
A. patient enters magnetic resonance imaging cavity, and the position scanned as required is to after each scanning coil cell location, it is determined that the imaging region of scanning and the scanning coil element number in described imaging region；
B. within the scope of the imaging region of described scanning, software system is to automatically select described each scanning coil unit from the center of imaging region to the direction at imaging region edge, and the quantity of the scanning coil unit of described selection is less than or equal to the overall channel number of system.If the scanning coil number of unit of system is not one_to_one corresponding (namely having carried out the situation that scanning coil cell signal merges) with passage, do not consider herein.The correspondence position of imaging region is scanned by the scanning coil unit chosen.If only the scanning coil unit of some quantity is in imaging region, the scanning coil unit entering imaging region is pointed out, and carried out manually supplementing selecting scanning coil unit according to actual scanning by user.When user manually selects, the quantity of selected scanning coil unit is less than or equally equal to the overall channel number of system, if the scanning coil number of unit of system is not one_to_one corresponding (namely having carried out the situation that scanning coil cell signal merges) with passage, do not consider too herein.
Thus just achieve, when magnetic resonance imaging, the scanning coil unit in areas imaging is carried out intelligentized selection, and significantly simplify scan operation, saved sweep time, the operating experience of user is greatly improved.
