Development of an automated CBCT‐based simulation‐free platform for expedited palliative radiotherapy on a conventional linear accelerator

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Conventional approaches for emergent or expedited palliative radiotherapy (RT) involve the application of cumbersome vendor‐provided solutions and/or multiple patient appointments to complete the RT workflow within a compressed timeframe.

AAPM‐RSS Medical Physics Practice Guideline 9.b: SRS‐SBRT

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract The purpose of this Medical Physics Practice Guideline (MPPG) is to describe the minimum level of medical physics support deemed prudent for the practice of linear‐accelerator, photon‐based (linac) stereotactic radiosurgery (SRS), and stereotactic body radiation therapy (SBRT) services.

Wide Incidence Angle-Insensitive Metamaterial Absorber for Both TE and TM Polarization using Eight-Circular-Sector

Scientific Reports, 2017
In this paper, a wide incidence angle-insensitive metamaterial absorber is proposed using eight-circular-sector (ECS). Under normal incidence, the proposed absorber shows high absorptivity at different polarizations due to its symmetric geometry.

On a paucity result in Incidence Geometry

, 2022
We obtain some asymptotic formulae (with power savings in their error terms) for the number of quadruples in the Cartesian product of an arbitrary set $A \subset \mathbf{R}$ and for the number of quintuplets in $A\times A$ for any subset $A$ of the prime field $\mathbf{F}_p$.

The implementation of knowledge‐based planning with partial OAR contours for prostate radiotherapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Intra‐ and inter‐observer contour uncertainty is a continuous challenge in treatment planning for radiotherapy. Our proposed solution to address this challenge is the use of partial contours for treatment planning, focusing on uninvolved or non‐overlapping portions of the organs‐at‐risk (OARs) with the planning target volume (PTV ...

High spatial resolution dosimetry for radiation oncology with “MagicPlates,” a new 976‐pixel monolithic silicon detector

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose We introduce the next generation of “MagicPlate” 2D monolithic pixelated semiconductor detectors – MagicPlate‐976 (MP976). It features a larger array area, higher spatial resolution, and does not require external triggering. We perform a comprehensive characterization for small‐field steep‐dose‐gradient dosimetry applications in ...

Successful Transradial Percutaneous Coronary Intervention in a Patient with Dextrocardia and Situs Inversus [PDF]

Journal of Clinical and Diagnostic Research, 2015
Dextrocardia with situs inversus is a rare clinical entity with an estimated incidence ranges from 1 in 8000 to 1 in10,000. Percutaneous intervention in patient with dextrocardia and situs inversus is clinically challenging due to abnormal orientation ...

Affine and Projective Planes [PDF]

, 2018
In this thesis, we investigate affine and projective geometries. An affine geometry is an incidence geometry where for every line and every point not incident to it, there is a unique line parallel to the given line.

Evaluation of the dose reduction effect of crystalline lens exposure in cone‐beam computed tomography with bismuth eye shield for image‐guided radiation therapy: An anthropomorphic phantom study

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract This study aimed to evaluate the dose‐exposure reduction effect of a crystalline lens with a bismuth eye shield using cone‐beam computed tomography (CBCT) for head image‐guided radiation therapy. The ocular surface dose of the head phantom (THRA‐1) is defined as a crystalline lens exposure dose and is measured using a radiophotoluminescence ...
