20120082356 | IMAGE DATA COMPRESSION AND DECOMPRESSION - A method of processing image data includes obtaining an image set that includes at least a first image and a second image, determining a deformation registration using the first and second images, wherein the act of determining the deformation registration is performed using a processor, performing image compression on at least a portion of the image set using the determined deformation registration to obtain compressed image data, and storing the compressed image data. A method of processing image data includes obtaining compressed image data, obtaining a deformation registration previously used to create the compressed image data, performing image decompression on the compressed image data using the deformation registration to obtain decompressed image data, wherein the act of performing the image decompression is performed using a processor, and storing the decompressed image data. | 04-05-2012 |
20120294497 | Method and Apparatus Pertaining to Images Used for Radiation-Treatment Planning - A radiation-treatment planning apparatus accesses first information regarding a first image that pertains to a patient's body at a first time as well as second information regarding a second image that pertains to the patient's body at a second, later time. The radiation-treatment planning apparatus then correlates components of the patient's body as appear in the second image with components that appear in the first image while treating the components as comprising rigid structures regardless of whether those components, in fact, are rigid structures. The first information can include segmentation information as pertains to the components. These teachings will accommodate a wide range of components including, but not limited to, organs, portions of organs, and even implanted man-made objects. | 11-22-2012 |

20130259338 | 4D CONE BEAM CT USING DEFORMABLE REGISTRATION - A method of obtaining a volumetric image includes obtaining a plurality of volumetric images, the volumetric images generated using respective sets of projection images, wherein the volumetric images and the respective sets of projection images correspond with different respective bins for a physiological cycle, and determining an additional volumetric image using one or more of the projection images from each of the sets that correspond with the different respective bins for the physiological cycle, wherein the act of determining the additional volumetric image is performed using a processor. | 10-03-2013 |
20130324783 | Apparatus and Method Pertaining to Optimizing a Radiation-Treatment Plan Using Historical Information - A control circuit operably couples to a memory having historical information stored therein. This historical information comprises information regarding delivered radiation doses to non-targeted patient volumes for a plurality of different volume presentations. The control circuit iteratively optimizes a radiation-treatment plan for a specific plan using that historical information. The aforementioned historical information can comprise delivered-dose metrics as correspond to different relative distances within given patients. The control circuit can employ such information to determine, for example, an estimated dosage (including, if desired, a corresponding range of estimated dosages) for at least one volume within the specific patient at a specific distance from a specific point of reference. The control circuit can compare such historical information against radiation-treatment plan optimization results to qualitatively assess the radiation-treatment plan optimization results. | 12-05-2013 |
