20140201670 | INTEGRATION OF USER INPUTS AND CORRECTION OF DEFORMATION VECTOR FIELD IN DEFORMABLE IMAGE REGISTRATION WORKFLOW - Adeformation vector field (DVF) (22)is computed that relatively spatially registers a first image (16)and a second image (14). A contour (26)delineating a structure in the first image is adapted using the DVF to generate an initial contour (52)for the structure in the second image. A final contour (56)is received for the structure in the second image. The DVF is corrected based on the initial and final contours for the structure in the second image to generate a corrected DVF (32). The correction may comprise computing an adjustment DVF (62)relating the initial and final contours and combining the DVF and the adjustment DVF to generate the corrected DVF.The final contour may be received by displaying the second image overlaid with the initial contour, and receiving user adjustments of the overlaid contour with the overlaid contour updated for each received user adjustment. | 07-17-2014 |
20140336438 | BEAM SEGMENT-LEVEL DOSE COMPUTATION AND TEMPORAL MOTION TRACKING FOR ADAPTIVE TREATMENT PLANNING - A treatment planning system for generating patient-specific treatment. The system including one or more processors programmed to receive a radiation treatment plan (RTP) for irradiating a target over the course of one or more treatment fractions, said RTP including a planned dose distribution to be delivered to the target, receive motion data for at least one of the treatment fractions of the RTP, receive temporal delivery metric data for at least one of the treatment fractions of the RTP, calculate a motion-compensated dose distribution for the target using the motion data and the temporal delivery metric data to adjust the planned dose distribution based on the received motion data and temporal delivery metric data, and compare the motion-compensated dose distribution to the planned dose distribution. | 11-13-2014 |
20150141733 | AUTOMATIC PLAN OPTIMIZATION FOR CHANGING PATIENT ANATOMY IN THE PRESENCE OF MAPPED DELIVERED DOSE FROM DELIVERED FRACTIONS - A therapy planning system and method generate an optimal treatment plan accounting for changes in anatomy. Therapy is delivered to the subject according to a first auto-planned optimal treatment plan based on a first image of a subject. A second image of the subject is received after a period of time. The second image is registered with the first image to generate a deformation map accounting for physiological changes. The second image is segmented into regions of interest using the deformation map. A mapped delivered dose is computed for each region of interest using the dose delivery goals and the deformation map. The first treatment plan is merged with the segmented regions of the second image and the mapped delivered dose during optimization. | 05-21-2015 |
