摘要： 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 two or more sets that correspond with different respective bins for the physiological cycle, wherein the act of determining the additional volumetric image is performed using a processor.

摘要： A control circuit controls real-time administration of a radiation-treatment plan that administers a therapeutic radiation dose to a patient. This includes compensating for a first movement as regards the application setting using a first treatment-administration modality and responding to detection of a second movement by using a second treatment-administration modality that is different from the first treatment-administration modality.

摘要： 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.
