摘要: Methods and systems are provided for automated graphical prescriptions with deep learning systems. In one embodiment, a method for a medical imaging system comprises acquiring, by the medical imaging system, localizer images of a subject, generating, by a trained neural network system, a graphical prescription using the localizer images, and performing, by the medical imaging system, a scan of the subject according to the graphical prescription. In this way, a desired region of interest of the subject may be accurately scanned with minimal input from an operator of the medical imaging system.

摘要: A controller that is operatively connected with a magnet assembly, which defines a target volume; and an image processor, which is configured to obtain calibration data from the controller; map B1 transmit intensity from the magnet assembly to the target volume, based on the calibration data; calculate a B1 transmit shading correction based at least on the map of B1 transmit intensity and on pulse sequence parameters; obtain k-space data of an imaging subject within the target volume from the controller operating the magnet assembly based on the pulse sequence parameters; develop an MR image from the k-space data; and apply the B1 transmit shading correction to the MR image.
