Abstract: A magnetic resonance imaging apparatus includes a controller and a deriving unit. The controller performs first imaging for acquiring first image data on a region including a target and the diaphragm, second imaging for acquiring, with application of motion detection pulses for detecting a respiratory phase, second image data including the target at a first respiratory phase and third image data including the target at a second respiratory phase different from the first respiratory phase, and third imaging for acquiring fourth image data. The deriving unit detects the position of the diaphragm from the first image data and derives a region to which the motion detection pulses are applied. In the performing of the second imaging, the controller detects a respiratory phase by the application of the detection pulses and controls timings at which the second image data and the third image data are acquired.

Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a processor and a memory. The memory stores processor-executable instructions that cause the processor to detect cross-sectional positions of a plurality of cross-sectional images to be acquired in an imaging scan from volume data; acquire the cross-sectional images in sequence based on the cross-sectional positions by executing the imaging scan; and after the first cross-sectional image is acquired in the imaging scan, generate a display image, and display the display image on a display, the display image being an image in which a cross-sectional position of a second cross-sectional image which is detected from the volume data is superimposed on the first cross-sectional image, the second cross-sectional image being a cross-sectional image before being acquired and intersecting with the first cross-sectional image.

Abstract: A magnetic resonance imaging apparatus acquires first imaging data of a three-dimensional image including a heart, having a plurality of two-dimensional first imaging area data superimposed one on top of another in parallel, and having a resolution at least in one direction different from a resolution in two other directions. A first axis is detected expressed in three dimensions relating to the heart from the three-dimensional first imaging data. A first vector is calculated passing through the first axis and having at least a predetermined resolution. First image data is generated on a plane passing through the first axis and the first vector from the first imaging data and a second axis is detected relating to the heart from the first image data, the second axis being a higher precision axis.

Abstract: A medical image diagnosis apparatus according to an embodiment includes a controller. The controller generates a plurality of candidates for a first cross-sectional image from three-dimensional image data obtained by taking images of a heart. The controller generates, from the three-dimensional image data, one or more second cross-sectional images each of which intersects the candidates for the first cross-sectional image. The controller displays in parallel on a display, the candidates for the first cross-sectional image, as well as the second cross-sectional images on each of which information is superimposed. The information indicates positional relationships between the candidates for the first cross-sectional image and the second cross-sectional image.

Abstract: First magnetic resonance imaging (MRI) three-dimensional heart image data includes a plurality of two-dimensional heart image data superimposed and having a resolution in at least one direction that is different from that in two other directions. A first axis is detected in the three-dimensional heart image data.
