4D-CT Simulation using Individually Optimized Contrast Enhancement (CE): A Phantom Study
Innovation/Impact: 4D-CT simulation has been widely used to estimate the respiratory motion of lung tumors and abdominal tumors for radiotherapy planning. However, most abdominal tumors (liver, pancreas etc.) cannot be readily visualized in CT without dynamic CE. It is desirable to combine a 4D-CT without CE and a CE 3D-CT into a CE 4D-CT so that we can both visualize the tumor and estimate its...
متن کاملA Simulation Study on Patient Setup Errors in External Beam Radiotherapy Using an Anthropomorphic 4D Phantom
Introduction Patient set-up optimization is required in radiotherapy to fill the accuracy gap between personalized treatment planning and uncertainties in the irradiation set-up. In this study, we aimed to develop a new method based on neural network to estimate patient geometrical setup using 4-dimensional (4D) XCAT anthropomorphic phantom. Materials and Methods To access 4D modeling of motion...
متن کاملAn Integrated Simulation System Based on Digital Human Phantom for 4D Radiation Therapy of Lung Cancer
Purpose: To develop and test an integrated simulation system based on the digital Extended Cardio Torso (XCAT) phantom for 4-dimensional (4D) radiation therapy of lung cancer. Methods: A computer program was developed to facilitate the characterization and implementation of the XCAT phantom for 4D radiation therapy applications. To verify that patient-specific motion trajectories are reproducib...

متن کاملEvaluation of a 4D Cone-Beam CT Reconstruction Approach Using an Anthropomorphic Phantom
We have previously developed image-guided navigation systems for thoracic abdominal interventions utilizing a three dimensional (3D) Cone-Beam CT (CBCT) image acquired at breath-hold. These systems required the physician to perform the intervention in a gated manner, with actions performed at the same respiratory phase in which the CBCT image was acquired. This approach is not always applicable...
