Embodiment Construction

[0043] An MRI apparatus according to an embodiment of the present invention will be described below with reference to the drawings. In addition, in all the drawings for explaining the embodiment of the present invention, the same reference numerals are assigned to the parts having the same functions, and the overlapping description thereof will be omitted.

[0044] Such as figure 1 As shown, the MRI apparatus of the present embodiment includes, as a main configuration, an imaging unit 100 that generates nuclear magnetic resonance on the subject and collects NMR signals; The computing unit 200 performs various calculations including image reconstruction; the storage device 300 stores data necessary for the processing of the imaging unit 100 and the computing unit 200, processing results, etc.; and a user interface unit ( UI) section 400.

[0045] The structure of the imaging unit 100 is the same as that of a general MRI apparatus, for example, figure 2 As shown, it is equi...

Abstract

The invention provides a magnetic resonance imaging apparatus and a control program therefor. Imaging failure of a positioning image due to the difference in the position or the size of a subject placed in the examination space is prevented, and accordingly, the extension of the examination time is prevented. A pre-scan for appropriately setting the imaging position for positioning imaging is automatically performed prior to the positioning imaging and the main imaging of an MRI apparatus, and a region where an examination part of a subject is present (the extent of the examination part) is detected using the measurement data. By using the detected extent of the examination part, it is possible to subsequently determine the imaging position or calculate the scan parameters used for imaging.

Description

technical field [0001] The present invention relates to a magnetic resonance imaging device and its control program. Background technique [0002] Magnetic resonance imaging (hereinafter referred to as MRI) equipment is to measure nuclear magnetic resonance (NMR) signals generated by the nuclear spins that make up the tissues of the subject, especially the human body, and to image the shape and organization of the head, abdomen, limbs, etc. in two dimensions. Or a device that visualizes in three dimensions. [0003] In examinations using an MRI apparatus, anatomically determined cross-sections are generally taken for each examination target site, but the body shape and bed posture of the subject differ from examination to examination. Therefore, even when the same imaging sequence is executed or analysis processing is performed, it is necessary to set and adjust the imaging position of the subject every time an examination is performed, or to capture images for scan paramet...
