A recently granted patent (Publication Number: US11925434B2) discloses a method and system for medical image fusion using a medical imaging system. The method involves acquiring two sets of scan data representing a patient with deformed anatomy, determining a deformation field aligning the anatomy of the two sets of scan data using a machine-learnt deep neural network, and generating a medical image from the scan data and the deformation field. The acquisition of scan data can be done with the same modality of scanner at different times or with different modalities of scanners. Additionally, the method includes dividing the first set of scan data into patches to determine the deformation field based on intensities and displacements for the patches relative to the second set of scan data.

The system for medical image fusion comprises at least one medical imaging system, an image processor, and a display. The imaging system acquires data representing a patient with tissue displacement, which is then registered using a deep-learnt neural network to output displacements. The image processor divides the data into patches and registers based on an output feature vector from the neural network, considering intensities and displacement vectors for the patches relative to the second data. This innovative method and system offer a sophisticated approach to medical image fusion, enabling accurate alignment of anatomical structures from different scan data sets, ultimately leading to the generation of comprehensive medical images for diagnostic and treatment purposes.
