15 صفحه اولA fast model for prediction of respiratory lung motion for image-guided radiotherapy: A feasibility study
Background: The aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one CT dataset. Materials and Methods: For each of six patients with different thorax sizes, two sets of CT images were obtained in single-breath-hold inhale and exhale stages in the supine position. The CT images were then ...
متن کاملAdaptive prediction of respiratory motion for motion compensation radiotherapy.
One potential application of image-guided radiotherapy is to track the target motion in real time, then deliver adaptive treatment to a dynamic target by dMLC tracking or respiratory gating. However, the existence of a finite time delay (or a system latency) between the image acquisition and the response of the treatment system to a change in tumour position implies that some kind of predictive...
متن کاملPredicting respiratory motion for four-dimensional radiotherapy.
Adapting radiation delivery to respiratory motion is made possible through corrective action based on real-time feedback of target position during respiration. The advantage of this approach lies with its ability to allow tighter margins around the target while simultaneously following its motion. A significant hurdle to the successful implementation of real-time target-tracking-based radiation...
متن کاملDiaphragm Tracking for Respiratory Motion Compensated Cardiac C-Arm CT
Long acquisition times of several seconds lead to image artifacts in cardiac C-arm CT. While ECG gating is able to select a certain heart phase, residual artifacts are mostly caused by respiratory motion. In order to improve image quality, it is important to accurately estimate the breathing motion that occurred during image acquisition. It has been shown that diaphragmmotion is correlated to t...
