Abstract
Images acquired during an image-guided treatment procedure sometimes exceed the scope of a reference library previously acquired for the purpose of monitoring and/or adjusting the treatment. In this situation, the reference library may be extended dynamically and/or in real time based on the newly acquired treatment images and/or other available information.
Claims41
A method for monitoring an anatomical region during treatment thereof, the method comprising:
- (a) prior to the treatment, establishing a library of reference image records of the anatomical region, each reference image record comprising (i) at least a reference image and (ii) data associated with the reference image including a thermal map corresponding to the reference image;
- (b) during the treatment, repeatedly
- (i) acquiring a treatment image of the anatomical region;
- (ii) comparing a currently acquired treatment image and the reference images in the library based on real-space or k-space image data to determine whether a reference image from the library matches the currently acquired treatment image according to an image-similarity criterion;
- and
- (iii) if none of the reference images in the library matches the currently acquired treatment image according to the image-similarity criterion, computationally deforming a treatment thermal map associated with one of previously acquired treatment images and extending the reference library by adding to the library a new reference image record comprising (A) a new reference image and (B) data associated with the new reference image including a new thermal map based at least in part on the deformed treatment thermal map;
- and
- (c) monitoring the anatomical region based at least in part on the acquired treatment images and the extended reference library.

A system for monitoring an anatomical region during treatment thereof, the system comprising:
- (a) an imaging apparatus for imaging the anatomical region;
- (b) memory for storing a library of reference image records comprising (i) reference images of the anatomical region and (ii) data associated with the reference images including thermal maps corresponding to the reference images;
- and
- (c) a computation unit configured to (i) repeatedly cause the imaging apparatus to acquire a treatment image of the anatomical region during the treatment, (ii) comparing a currently acquired treatment image and the reference images in the library based on real-space or k-space image data to determine whether any of the reference images in the library matches the currently acquired treatment image according to an image-similarity criterion, (iii) if none of the reference images in the library matches the currently acquired treatment image, computationally deforming a treatment thermal map associated with one of previously acquired treatment images and extend the reference library by adding to the library a new reference image record comprising (A) a new reference image and (B) data associated with the new reference image including a new thermal map based at least in part on the deformed treatment thermal map, and (iv) monitor the anatomical region based at least in part on the acquired treatment images and the extended reference library.
