摘要： When delineating anatomical structures in a medical image of a patient for radiotherapy planning, a processor (18) detects landmarks (24) in a low-resolution image (e.g., MRI or low-dose CT) and maps the detected landmarks to reference landmarks (28) in a reference contour of the anatomical structure. The mapped landmarks facilitate adjusting the reference contour to fit the anatomical structure. The adjusted reference contour data is transformed and applied to a second image using a thin-plate spline, and the adjusted high-resolution image is used for radiotherapy planning.

摘要： In a diagnostic imaging system (10), a user interface (82) facilitates viewing of 4D kinematic data sets. A set of reference points is selected in a first 3D image to designate an anatomical component. An algorithm (104) calculates a propagation of the selected reference points from the first 3D image into other 3D images. Transforms which describe the propagation of the reference points between 3D images are defined. An aligning algorithm (112) applies inverse of the transforms to the 3D images to define a series of frames for the video processor (120) to display, in which frames the designated anatomical component defined by the reference points in each of the 3D images remains fixed while the other portions of the anatomical region of interest move relative to the fixed designated anatomical component.

摘要： A contouring module (22, 24) iteratively adjusts contours delineating a radiation target region and risk regions in a planning image. An intensity modulation optimization module (30) generates a radiation therapy plan conforming with dosage or dosage constraints (26) for the radiation target region and the risk regions delineated by the contours. A differential analysis module (40) is configured to invoke the intensity modulation optimization module (30) to estimate partial derivatives of an output of the intensity modulation optimization respective to the contours. The contouring module (22, 24) is configured to invoke the differential analysis module (40) after each iterative contour adjustment to estimate the partial derivatives respective to the contour segments and to render the contour segments on a display of the planning image with the contour segments coded based on the estimated partial derivatives to indicate impact of the contour segments on the intensity modulation optimization.

摘要： When adapting models of anatomical structures in a patient for diagnosis or therapeutic planning, an atlas (26) of predesigned anatomical structure models or image volumes can be accessed, and a segmentation of one or more such structures can be selected and overlaid on an a 3D image of corresponding structure(s) in a clinical image (52) of a patient. A user can click on an initially unapproved segmentation 5 landmark (72) on the patient image (52), reposition the unapproved landmark, and approve the repositioned landmark. Remaining unapproved landmarks (72) are then repositioned as a function of the position of the approved landmark (92) using one or more interpolation techniques to adapt the model to the patient image on the fly.
