Comparison of liver stereotactic body radiotherapy plans based on free breathing and averaged CTs after trans-arterial chemoembolization using lipiodol. [PDF]
J Appl Clin Med PhysAbstract Purpose To identify which CT set is more suitable for predicting the four‐dimensional (4D) cumulative dose distribution in liver stereotactic body radiotherapy (SBRT) with lipiodol retention. Methods For 15 patients, who underwent liver SBRT after trans‐arterial chemoembolization (TACE), volumetric modulated arc therapy (VMAT) plans were ...

Development of a LINAC head model for the CyberKnife VSI-System using EGSnrc Monte Carlo system. [PDF]
J Appl Clin Med Phys, 2023 Abstract Introduction In order to understand the interaction processes of photons and electrons of the CyberKnife VSI‐System, a modeling of the LINAC head must take place. Here, a Monte Carlo simulation can help. By comparing the measured data with the simulation data, the agreement can be checked. Materials and methods For the Monte Carlo simulations,

High spatial resolution dosimetry for radiation oncology with "MagicPlates," a new 976-pixel monolithic silicon detector. [PDF]
J Appl Clin Med PhysAbstract 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 ...

Enhancing targeted doses: Low-energy photon lipiodol-enhanced radiotherapy (LEPERT) for liver cancer patients. [PDF]
J Appl Clin Med PhysAbstract Objectives This study proposes a novel approach, “Low‐energy photon Lipiodol‐Enhanced Radiotherapy” (LEPERT), for patients with liver cancer. Moreover, we evaluate the dose difference of the conventional treatment planning with 10 MV X‐ray beam (MV‐plan) and LEPERT.
