Image reconstruction using multiple reconstruction chains for radiation therapy

A computer system, comprising:

• a processor;
• and
• a non-transitory computer-readable medium having stored thereon instructions that, when executed by the processor, cause the processor to perform the following:
• obtain projection image data associated with a target structure within a patient requiring radiation therapy;
• generate, using a first image reconstruction chain, first volume image data associated with the target structure based on the projection image data;
• generate and display, on a display device, a first user interface (UI) view for a user to interact with the first volume image data;
• generate, using a second image reconstruction chain, second volume image data associated with the target structure based on at least one of the following:
• the projection image data and the first volume image data;
• and
• generate and display, on the display device, a second UI view for the user to interact with the second volume image data.

A radiation therapy system, comprising:

• an imaging system to acquire projection image data associated with a target structure within a patient requiring radiation therapy;
• a display device;
• and
• a computer system configured to:
• generate, using a first image reconstruction chain, first volume image data associated with the target structure based on the projection image data;
• generate and display, on the display device, a first user interface (UI) view for a user to interact with the first volume image data;
• generate, using a second image reconstruction chain, second volume image data associated with the target structure based on at least one of the following:
• the projection image data and the first volume image data;
• and
• generate and display, on the display device, a second UI view for the user to interact with the second volume image data.
