Classification: CPC A  G | IPC A  G

Claim 14:
15. A non-transitory computer-readable storage medium, storing a computer program, the computer program, when executed by a processor, cause the processor to perform a plurality of operations comprising:
obtaining dynamic contrast enhanced (DCE) magnetic resonance images corresponding to a plurality of time points for a same detection target;
determining average pixel grayscale values of images of a same lesion region in the DCE magnetic resonance images of the plurality of time points respectively;
determining a time to peak according to the average pixel grayscale values corresponding to the plurality of time points; and
generating a first-stage time-intensity image before the time to peak and a second-stage time-intensity image after the time to peak respectively according to the DCE magnetic resonance images of the plurality of time points and the time to peak, the first-stage time-intensity image and the second-stage time-intensity image being 3D images, and a pixel grayscale value of each pixel in the first-stage time-intensity image and the second-stage time-intensity image representing a change rate of blood supply intensity and reflecting a severity level of a lesion corresponding to the lesion region.
