Abstract
Disclosed herein are a method and a system for creating a registered image that integrates the information of CT and CBCT images. With the present method and system, medical practitioners can precisely transform the information of CT image-based treatment plan into the CBCT image so as to accurately control the dosage and location of a radiation therapy. Accordingly, also disclosed herein are methods of treating a cancer in the subject with the aid of the method and/or system of the present disclosure.
Claims17
A computer implemented method for creating a registered image from a plurality of computed tomography (CT) images and a plurality of cone-beam computed tomography (CBCT) images, comprising,
- (a) respectively contouring the plurality of CT images and the plurality of CBCT images to create a plurality of contoured CT images and a plurality of contoured CBCT images;
- (b) respectively extracting the plurality of contoured CT images and the plurality of contoured CBCT images of the step (a) to create a plurality of extracted CT images and a plurality of extracted CBCT images;
- (c) respectively constructing a three dimensional (3D) CT model and a 3D CBCT model from the plurality of extracted CT images and the plurality of extracted CBCT images of the step (b);
- (d) creating a registered 3D CBCT model by matching the 3D CBCT model to the 3D CT model of the step (c);
- (e) respectively generating a plurality of transverse CT images and a plurality of transverse CBCT images from the 3D CT model of the step (c) and the registered 3D CBCT model of the step (d);
- (f) respectively selecting one target transverse CT image and one target transverse CBCT image from the plurality of transverse CT images and the plurality of transverse CBCT images of the step (e);
- and
- (g) registering the respectively selected target transverse CT image and CBCT image of the step (f) to create the registered image.
