A multicentre observational study evaluating image-guided radiotherapy for more accurate partial-breast intensity-modulated radiotherapy: comparison with standard imaging technique

Efficacy and Mechanism Evaluation, 2014
Background: Whole-breast radiotherapy (WBRT) is the standard treatment for breast cancer following breast-conserving surgery. Evidence shows that tumour recurrences occur near the original cancer: the tumour bed.

Evaluation of inter‐fractional anatomical variations due to compression belt placement reproducibility using MR‐guided radiotherapy treatment fraction images

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Abdominal compression (AC) using a belt‐based system is widely employed in radiation therapy to limit respiration‐induced target motion for abdominal and hepatic malignancies. While AC has demonstrated efficacy in reducing intrafraction motion amplitude, the interfractional anatomical consequences of daily compression belt (CB ...

Post-Prostatectomy Image-Guided Radiotherapy: The Invisible Target Concept

Frontiers in Oncology, 2017
In the era of intensity-modulated radiation therapy, image-guided radiotherapy (IGRT) appears crucial to control dose delivery and to promote dose escalation while allowing healthy tissue sparing.

Towards adaptive radiotherapy: Comparing HyperSight and standard CBCT reconstructions on a C‐Arm Linac

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is integral to image‐guided radiation therapy and increasingly used for adaptive radiotherapy and CBCT‐based dose calculation. Conventional kV‐CBCT systems on C‐arm TrueBeam linacs with Feldkamp–Davis–Kress (FDK) reconstruction have historically been limited by reduced Hounsfield Unit (HU ...

IGRT method for breast cancer

, 2016
Tato bakalářská práce se zaměřuje na použití metody IGRT v radioterapii při léčbě rakoviny pomocí ověření požadované polohy pacienta před každou frakcí, díky čemuž se dávka RTG záření nedostává do okolních tkání v nežádoucím množství.

Association of blood IgG with tumor necrosis factor-alpha and clinical course of chronic lymphocytic leukemiaResearch in context

EBioMedicine, 2018
The intrinsic humoral immunodeficiency of chronic lymphocytic leukemia (CLL) is often managed with immunoglobulin replacement therapy (IgRT) to maintain IgG levels in the low-normal range (6–8 g/L) but optimal targets for IgG and timing to commence IgRT ...

Routine physics work efficacy and efficiency improvement through a shared‐duty physicist‐of‐the‐day model in a multi‐hospital radiation oncology network

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Large multi‐hospital radiation oncology networks often rely on site‐exclusive physicist coverage models that can lead to imbalanced workload distribution, inconsistent task execution, communication fragmentation, and vulnerability to delayed or missed quality checks.
