The invention provides an image reconstruction system and method capable of being continuously upgraded, and relates to the technical field of image reconstruction, and the method comprises the steps: continuously recording a magnetic resonance image obtained through the scanning of intelligent magnetic resonance equipment; when the magnetic resonance images reach a first preset number, training to obtain an image reconstruction model; after the image reconstruction model is obtained through training, when a second preset number of magnetic resonance images are recorded, each magnetic resonance image is adopted to carry out training once to obtain a corresponding optimized reconstruction model; when the image reconstruction effect of the optimized reconstruction model is better than that of the image reconstruction model, the optimized reconstruction model is stored as an image reconstruction module so as to realize sustainable upgrading of the image reconstruction model; and calling the image reconstruction model to perform image reconstruction on the currently scanned magnetic resonance image as a magnetic resonance scanning result to be output. The method has the beneficial effects that targeted and continuous image reconstruction optimization is carried out according to the scanned content and environmental noise characteristics of the intelligent magnetic resonance equipment, and the image reconstruction quality can be continuously improved.
Description
technical field [0001] The invention relates to the technical field of image reconstruction, in particular to an image reconstruction system and method which can be continuously upgraded. Background technique [0002] For magnetic resonance imaging (MRI), users (such as doctors or scientific researchers) usually want to complete the scan in a shorter time while maintaining the image quality, or obtain better image quality under the premise of the same scan time , which all depend on excellent reconstruction algorithms. At present, magnetic resonance reconstruction algorithms can be divided into the most traditional fast Fourier transform algorithm, parallel imaging reconstruction algorithm based on multi-coils, reconstruction algorithm based on compressed sensing, and reconstruction algorithm based on deep learning. [0003] Existing magnetic resonance equipment is preset with built-in reconstruction algorithms at the factory, which lacks flexibility. Even if these algorith...
