The accurate registration of 3D multi-modal medical images taken in different patient positions, such as supine and upright, is crucial for numerous clinical applications, including diagnosis, treatment planning, and monitoring disease progression. However, position changes and tissue deformations pose significant challenges to image registration, as they can cause substantial discrepancies between scans. These discrepancies can obscure critical in treatment implementation and impede the precise alignment necessary for effective clinical interventions.
This thesis aims to develop an innovative end-to-end framework leveraging deep learning to achieve precise registration between 3D multi-modal images taken at supine and upright positions. The primary objective is to develop a robust model that can recover bone structures and articulate models to align images accurately, accounting for positional changes and couple them with a dense deformation model to deal with tissue/anatomical changes due gravity. This model will be designed to automatically adjust for anatomical variations and the complex, non-rigid deformations that occur when a patient shifts from one position to another. Prostate cancer treatment delivery where registration between supine MR scans and Upright CT scans in the context of radiotherapy with a prospective clinical trial/evaluation will be used to demonstrate the clinical relevance of the developed technology.
