HERMES: A Hybrid Ensemble for Head-and-Neck Tumor Segmentation, TN Staging, and Recurrence-Free Survival on PET/CT
Kai Wang, Meixu Chen, Elie Nasr +2
We present HERMES (Hybrid Ensemble for Radiotherapy-target segmentation, Malignancy staging, and Event-free Survival), a single containerized algorithm for the three HECKTOR 2026 s…
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…
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…
Quantifying allowable motion to achieve safe dose escalation in pancreatic SBRT
Yijun Ding, Warren G. Campbell, Moyed Miften +4
Tumor motion plays a key role in the safe delivery of Stereotactic Body Radiotherapy (SBRT) for pancreatic cancer. The purpose of this study was to use tumor motion data measured i…
Neural network dose models for knowledge-based planning in pancreatic SBRT
Warren G. Campbell, Moyed Miften, Lindsey Olsen +4
Stereotactic body radiation therapy (SBRT) for pancreatic cancer requires a skillful approach to deliver ablative doses to the tumor while limiting dose to the highly sensitive duo…
Automated target tracking in kilovoltage images using dynamic templates of fiducial marker clusters
Warren G. Campbell, Moyed Miften, Bernard L. Jones
Purpose: Implanted fiducial markers are often used in radiotherapy to facilitate accurate visualization and localization of tumors. Typically, such markers are used to aid daily pa…
Adaptive motion mapping in pancreatic SBRT patients using Fourier transforms
Bernard L. Jones, Tracey Schefter, Moyed Miften
Recent studies suggest that 4DCT is unable to accurately measure respiratory-induced pancreatic tumor motion. In this work, we assessed the daily motion of pancreatic tumors treate…
Calculating tumor trajectory and dose-of-the-day using cone-beam CT projections
Bernard L. Jones, David Westerly, Moyed Miften
Purpose: Cone-beam CT (CBCT) projection images provide anatomical data in real-time over several respiratory cycles, forming a comprehensive picture of tumor movement. We developed…
Dosimetric and Deformation Effects of Image-Guided Interventions during Stereotactic Body Radiation Therapy of the Prostate using an Endorectal Balloon
Bernard L. Jones, Gregory Gan, Quentin Diot +3
During Stereotactic Body Radiotherapy (SBRT) for the treatment of prostate cancer, an inflatable endorectal balloon (ERB) may be used to reduce motion of the target and reduce the…
