Abstract

This invention relates to image reconstruction using multiple reconstruction chains for radiotherapy. In one example, a computer system can acquire projected image data associated with a target structure within a patient. The computer system can generate first volumetric image data based on the projected image data using a first image reconstruction chain. The computer system can generate and display a first user interface (UI) view on a display device for a user to interact with the first volumetric image data. The computer system can also generate second volumetric image data based on at least one of the projected image data and the first volumetric image data using a second image reconstruction chain. The computer system can generate and display a second UI view on a display device for a user to interact with the second volumetric image data.
