Generating synthetic x-ray images and object annotations from CT scans for augmenting x-ray abnormality assessment systems

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;
• outputting the output image;
• generating one or more additional synthetic images in the second modality from the input medical image;
• and
• repeating the upsampling, the generating the output image, and the outputting steps for each respective additional synthetic image of the one or more additional synthetic images using the respective additional synthetic image as the synthetic image to generate a plurality of output images.

An apparatus comprising:

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

A non-transitory computer readable medium storing computer program instructions, the computer program instructions when executed by a processor cause the processor to perform operations comprising:
