Problems solved by technology

[0004] However, most of the current research on exploring radio frequency signals is based on the experience of sequence designers and the process of determining corresponding parameters for patients with different conditions. Image analysis mainly relies on clinicians to manually identify lesions and normal tissues through film reading. Due to the limitations of the naked eye, some lesions with small contrast difference with surrounding tissue or small size are easy to be missed, and there are differences in accuracy and repeatability between different readers

Abstract

The invention discloses a magnetic resonance intelligent imaging method, device and equipment and a storage medium. The method comprises the steps of scanning a preset part of a patient to obtain a first scanning image; selecting a first positioning point and a second positioning point in the first scanning image, and acquiring image information of the first positioning point and the second positioning point; determining a target imaging parameter corresponding to the optimal image information difference between the first positioning point and the second positioning point according to a preset target function, and / or determining a target radio frequency sequence function corresponding to the optimal image information difference between the first positioning point and the second positioning point according to a variational optimization method; and scanning the preset part of the patient again according to the target imaging parameter and / or the target radio frequency sequence function to obtain a second scanning image. The invention can solve the problem that small lesions are missed due to the fact that image analysis of magnetic resonance imaging needs to depend on manual recognition of clinicians; therefore, the diagnosis accuracy of magnetic resonance imaging and objectivity and standardization of image reports are improved, and the working efficiency of the clinicians is improved.

Description

technical field [0001] Embodiments of the present invention relate to magnetic resonance imaging technology, and in particular to a magnetic resonance intelligent imaging, device, equipment, and storage medium. Background technique [0002] Magnetic resonance imaging (MRI) technology is a medical imaging diagnostic technology that was put into clinical application in hospitals in the 1980s. At present, MRI technology is an important clinical examination method, and different pulse sequences can be used to obtain information on different aspects of human tissue structure, function, and metabolism. Magnetic resonance imaging has rich contrast information, high resolution, can be sliced ​​in any direction, and has no radiation damage, so it plays an important role in clinical diagnosis. [0003] At present, the main process of MRI technology includes: setting the imaging parameters of magnetic resonance imaging, data acquisition of magnetic resonance imaging, image reconstruct...
