Evaluation of dosimetric misrepresentations from 3D conventional planning of liver SBRT using 4D deformable dose integration
The purpose of this study is to evaluate dosimetric errors in 3D conventional plan- ning of stereotactic body radiotherapy (SBRT) by using a 4D deformable image registration (DIR)-based dose-warping and integration technique. Respiratory- correlated 4D CT image sets with 10 phases were acquired for four consecutive patients with five liver tumors. Average intensity projection (AIP) images were ...

Energy matching based on deformable templates
Snakes, or active contours, have been previously used in computer vision applications to locate and identify objects. However, problems associated with initialization, poor convergence to boundary concavities and high computational complexity, have limited their utility. In this paper, we present a scheme for object localization and classification based on inexact description of the shape. The ...
متن کاملCorrelation of radioactive hemin formation with morphologic alterations in cultures of human bone marrow.
I N A PRECEDING PAPER a method was presented for observing maturation of human erythroblasts in a clot-free cell suspension culture system in vitro.’ The parameter of maturation was the increase of orthochromic cells (luring the period of incubation. The present study was undertaken to determine the extent to which the morphologic parameter of maturation correlated with a basic aspect of erythr...
متن کامل[Availability of using diaphragm matching in stereotactic body radiotherapy (SBRT) at the time in breath-holding SBRT for liver cancer].
PURPOSE Liver image guided radiation therapy (IGRT) based on bone matching risks generating serious target positioning errors for reasons of lack of reproducibility of expiration breath hold. We therefore investigated the feasibility of 3D image matching between planning CT images and pretreatment cone-beam computed tomography (CBCT) images based on diaphragm surface matching. METHOD 27 liver...
