[0002] At present, GRE2D sequences are usually used to acquire abdominal t1-weighted images. During the acquisition of abdominal magnetic resonance images, the patient needs to hold his breath. The entire acquisition time lasts for more than 20 seconds. The patient cannot hold his breath for such a long time, so it needs to be divided into two Acquisition, that is, the patient needs to hold two breaths, but the position of the diaphragm muscle in the two breaths may be inconsistent, resulting in deviations in the positions of the two acquisition images, and the quality of the generated MRI images is poor

Embodiment Construction
[0040] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0041] The inventor found through research that GRE2D sequences are usually used to acquire abdominal t1-weighted images. During the process of acquiring abdominal magnetic resonance images, patients need to hold their breath, and the entire acquisition time lasts for more than 20 seconds. Patients cannot hold their breath for such a long time, so...

The invention discloses a magnetic resonance image generation method and computer equipment. The method comprises the following steps: determining a full acquisition position and a plurality of under-acquisition positions of a to-be-processed object; determining full-acquisition K space data of the full-acquisition position; determining a plurality of pieces of under-acquisition K space data corresponding to the plurality of under-acquisition positions, and determining a plurality of pieces of target K space data corresponding to the plurality of under-acquisition positions based on the full-acquisition K space data and the plurality of pieces of under-acquisition K space data; and generating a magnetic resonance image corresponding to the to-be-processed object according to the fully-acquired K space data and the plurality of target K space data. In the present invention, one piece of full-acquisition K space data and a plurality of pieces of under-acquisition K space data are acquired, the under-acquisition time is shorter than the full-acquisition time, the magnetic resonance image generation time is effectively shortened, the magnetic resonance image is generated by adopting the target K space data, a patient can obtain the magnetic resonance image only by holding breath once, and the imaging quality of the magnetic resonance image is improved.
Description
technical field [0001] The invention relates to the field of magnetic resonance, in particular to a method for generating magnetic resonance images and computer equipment. Background technique [0002] At present, GRE2D sequences are usually used to acquire abdominal t1-weighted images. During the acquisition of abdominal magnetic resonance images, the patient needs to hold his breath. The entire acquisition time lasts for more than 20 seconds. The patient cannot hold his breath for such a long time, so it needs to be divided into two Acquisition, that is, the patient needs to hold two breaths, but the position of the air diaphragm muscle of the patient may not be consistent in two breaths, resulting in deviations in the positions of the two acquisition images, and the quality of the generated MRI images is poor. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The main purpose of the present invention is to pr...
