Abstract
A magnetic resonance imaging protocol includes an acquisition segment to control an acquisition sequence to acquire magnetic resonance signals at a lower main magnetic field strength. A reconstruction segment controls reconstruction of a diagnostic magnetic resonance image from the magnetic resonance signals at a lower main magnetic field strength. A segmentation segment controls segmentation of a predetermined image detail of the diagnostic magnetic resonance image. In the magnetic resonance imaging protocol, the acquisition sequence has a set of imaging parameters that cause the image quality of the diagnostic magnetic resonance to be similar to the image quality of the magnetic resonance training images, e.g., acquired at 7 T. The segmentation segment includes an initialization portion which controls (i) access to a set of magnetic resonance training images acquired at main magnetic field of a higher main magnetic field strength (ii) registration of the diagnostic magnetic resonance image to one or more of the magnetic resonance training images and (iii) a segmentation proper applied to the diagnostic image to segment the predetermined detail from the registered diagnostic magne…
