1. A computer implemented method comprising:
receiving an input medical image in a first modality;
generating a synthetic image in a second modality from the input medical image;
upsampling the synthetic image to increase a resolution of the synthetic image;
generating an output image to simulate image processing of the upsampled synthetic image; and
outputting the output image,
wherein:
the input medical image comprises annotations,
generating a synthetic image in a second modality from the input medical image comprises translating the annotations to correspond to the synthetic image, and
upsampling the synthetic image to increase a resolution of the synthetic image comprises resampling the translated annotations to the resolution of the upsampled synthetic image.
