SU-D-BRA-03: Simultaneous MV-KV Imaging for Intra-Fractional Motion Management during Volume Modulated Arc Therapy (VMAT) Delivery on the Varian TrueBeam
Autor: P Wang, J Xiong, P Zhang, G Mageras, H Pham, R Regmi, D Morf, M Hunt
Publikováno v: Medical physics. 39(6Part3)
Purpose: To evaluate a MV‐kV intra‐fractional imaging technique for use during volume modulated arc therapy (VMAT) with the Varian TrueBeam. Methods: MV‐kV image pairs were acquired intra‐fractionally during VMAT delivery. kV images (11 fps)

SU-D-BRA-03: What Image Features Are Useful for Tumor Segmentation in Multi-Modal Images?
Autor: Y Hu, G Mageras, Michael Grossberg
Publikováno v: Medical Physics. 42:3213-3213
Purpose: We hypothesize that derived image features will improve accuracy of segmenting gross tumor volume (GTV) using (semi-)automatic methods when compared with raw intensities. Features from multi-modal images, however, require more CPU time and m

SU-C-BRB-07: Optimizing Fiducial Visibility On Periodically Acquired Megavoltage and Kilovoltage Image Pairs During Volumetric Modulated Arc Therapy
Autor: M Hunt, H Laura, P Zhang, B Ravindranath, G Mageras, P Wang
Publikováno v: Medical Physics. 42:3195-3195
Purpose: Robust detection of implanted fiducials is essential for monitoring intra-fractional motion during hypo-fractionated treatment. We developed a plan optimization strategy to ensure clear visibility of implanted fiducials, and facilitate 3D lo

A method for determining the gantry angle for megavoltage cone beam imaging
Autor: J, Sillanpaa, J, Chang, H, Amols, G, Mageras
Publikováno v: Medical physics. 32(2)
Accurate knowledge of gantry angle is essential in megavoltage cone beam imaging (MVCBI) with an electronic portal imager. We present a method for determining the gantry angle by detecting multileaf collimator (MLC) leaf positions in projection image

SU-FF-T-352: Predicting the Parameters of a Prostate IMRT Objective Function Based On Dose Statistics Under Fixed Parameter Settings
Autor: L Happersett, A Jackson, Richard J. Radke, J Yang, E Yorke, Chen-Shou Chui, G Mageras, R Lu
Publikováno v: Medical Physics. 34:2482-2483
Purpose: To simplify the trial‐and‐error process of adjusting objective function parameters (e.g. weights, dose limits) in prostate IMRT planning, we present a feasibility study showing that machine learning followed by a sensitivity‐driven gre
