Positioning in magnetic resonance imaging
First Claim
1. A method of magnetic resonance imaging in which positioning for a diagnostic scan is carried out prior to the diagnostic scan to obtain a magnetic resonance image of an object being examined, the method comprising the steps of:
- preparing a three-dimensional image data consisting of a plurality of tomographic image data of a diagnostic portion of the object;
designating data of a tomographic image among the three-dimensional image data as data of a pilot image;
displaying the pilot image;
placing a linear region of interest on the displayed pilot image;
editing image data of a cross-section from the three-dimensional image data, the cross-section passing through the linear region of interest in a space of the three-dimensional image data;
displaying the edited image data as a prediction image representing the magnetic resonance image positionally obtainable when carrying out the diagnostic scan; and
judging whether or not said prediction image is desired in response to a signal manually supplied for the prediction image.

Abstract
In magnetic resonance imaging, prepared first is a three-dimensional image data consisting of a plurality of tomographic image data of a diagnostic portion of an object being examined. Then, data of a pilot image in the three-dimensional image data are designated, and the pilot image is displayed. Then, a linear ROI (region of interest) is placed on the displayed pilot image. Then, image data of a cross-section are edited from the three-dimensional image data, the cross-section passing through the linear ROI in a space of the three-dimensional image data. On the basis of the edited image data of the cross-section, a prediction image for scan is displayed.
