CROSS-MODALITY IMAGE SYNTHESIS
First Claim
1. A system for image synthesis, comprising:
- a non-transitory memory device for storing computer readable program code; and
a processor device in communication with the memory device, the processor being operative with the computer readable program code to perform steps includingtraining a first model using first pairs of complementary images and corresponding first ground truth images, wherein the first pairs of complementary images are acquired by magnetic resonance (MR) imaging and the first ground truth images are acquired by computed tomography (CT), wherein the first pairs of complementary images and the first ground truth images represent a first view of a region of interest,training a second model using second pairs of complementary images and corresponding second ground truth images, wherein the second pairs of complementary images are acquired by MR imaging and the second ground truth images are acquired by CT, wherein the second pairs of complementary images and the second ground truth images represent a second view of the region of interesttraining a combinational network to combine features from the first and second models, andgenerating at least one synthetic CT image by passing current MR images through the trained first or second model and the combinational network, wherein the current MR images represent the first or second view of the region of interest.

Abstract
A framework for cross-modality image synthesis. A first and second model may be trained using respective first and second pairs of complementary images and corresponding first and second ground truth images that represent first and second views of a region of interest. The first and second pairs of complementary images may be acquired by a first modality and the first and second ground truth images may be acquired by a second modality. A combinational network may further be trained to combine features from the first and second models. At least one synthetic second modality image may then be generated by passing current images through the trained first or second model and the combinational network, wherein the current images are acquired by the first modality and represent the first or second view of the region of interest.
