Incorporating internal anatomy in clinical radiotherapy setups
First Claim
Patent Images
1. A method for positioning a patient prior to administration of an electron treatment using a linear accelerator, the method comprising:
- obtaining a three-dimensional (3D) diagnostic image of a patient situated on a patient support device prior to the electron treatment;
segmenting the 3D diagnostic image to define an internal anatomical feature within a patient'"'"'s breast;
annotating the segmented image to identify an external feature on a surface of the patient'"'"'s skin;
displaying the annotated image from a beam'"'"'s-eye vie of the linear accelerator;
iteratively modifying the physical setup of the patient by at least one of rotating a gantry of the linear accelerator and adjusting the patient support device until the internal and external features are aligned;
updating the display to show a perspective of the beam'"'"'s-eye view in response to the modification of the treatment parameter until a direction of an electron beam of the linear accelerator is aligned along the beam'"'"'s-eye view to the internal feature; and
directing a single electron beam of the linear accelerator along the beam'"'"'s-eye view toward the internal feature.

Abstract
A diagnostic image of internal anatomical features of a patient is annotated with representations of external features, such that both can be viewed together on a visual display. Adjustments to various treatment parameters relating to the administration of radiation therapy are provided, and the displayed image is automatically updated based on the adjustments.
