A 2D antiscatter grid and scatter sampling based CBCT method for online dose calculations during CBCT guided radiation therapy of pelvis
Farhang Bayat, Brian Miller, Yeonok Park +7
Online dose calculations before radiation treatment have applications in dose delivery verification, plan adaptation, and treatment planning. We propose a novel CBCT imaging pipeli…
2D antiscatter grid and scatter sampling based CBCT pipeline for image guided radiation therapy
Farhang Bayat, Dan Ruan, Moyed Miften +1
Poor tissue visualization and quantitative accuracy in CBCT is a major barrier in expanding the role of CBCT imaging from target localization to quantitative treatment monitoring a…
Feasibility of dual-energy CBCT material decomposition in the human torso with 2D anti-scatter grids and grid-based scatter sampling
Cem Altunbas
Background: Dual-energy (DE) imaging techniques in cone-beam computed tomography (CBCT) have potential clinical applications, including material quantification and improved tissue…
Concurrent kilovoltage CBCT imaging and megavoltage beam delivery: Suppression of cross-scatter with 2D antiscatter grids and grid-based scatter sampling
Farhang Bayat, Mohamed Elsayed Eldib, Brian Kavanagh +2
The concept of using kilovoltage (kV) and megavoltage (MV) beams concurrently has potential applications in cone beam computed tomography (CBCT) guided radiation therapy, such as s…
Evaluation of scatter rejection and correction performance of 2D antiscatter grids in cone beam computed tomography
Yeonok Park, Timur Alexeev, Brian Miller +2
Purpose: We have been investigating 2D antiscatter grids (2D ASG) to reduce scatter fluence and improve image quality in cone beam computed tomography (CBCT). In this work, two dif…
Feasibility of 2D antiscatter grid concept for flat panel detectors: preliminary investigation of primary transmission properties
Cem Altunbas, Yuncheng Zhong, Chris C. Shaw
Suppressing the effects of scattered radiation in flat panel detector, FPD, based CBCT still remains to be a challenge. To address the scatter problem, we have been investigating t…
