Abstract

In order to provide a magnetic resonance imaging apparatus capable of maximizing the effectiveness of an automatic alignment function without increasing the workload of the operator even when imaging test areas that have multiple test sections, when setting the imaging positions for an test area that has multiple test sections, an automatic alignment processing that automatically detects all of the test sections of the test area on a previously acquired scanogram image is first performed. At the positions detected by the automatic alignment processing, a stack is displayed on the scanogram image.

Description

technical field [0001] The present invention relates to an assisting technique for setting an imaging position in a magnetic resonance imaging (hereinafter referred to as “MRI”) apparatus. Background technique [0002] Magnetic resonance imaging (hereinafter referred to as "MRI") device is to measure nuclear magnetic resonance (hereinafter referred to as "NMR" or echo) signals generated by the nuclear spins that make up the subject, especially human tissue, in 2-dimensional or 3-dimensional A device that visualizes the shape or function of its head, abdomen, limbs, etc. in a three-dimensional manner. NMR signals are encoded with different phases by a gradient magnetic field, and frequency-encoded, and are measured as time-series data. An image is reconstructed by performing 2D or 3D Fourier transform on the NMR signal. The region to be imaged is called an imaging slice, and its position (imaging position) is set by the operator via GUI or the like. The imaging position de...
