4D-CT strain analysis for biomechanical characterization of COPD in patients undergoing radiotherapy planning: an exploratory study [PDF]

open access: yesFrontiers in Medicine
BackgroundChronic obstructive pulmonary disease (COPD) is characterized by progressive airflow limitation and altered pulmonary biomechanics. While conventional spirometry provides global functional information, it cannot assess regional heterogeneity ...

CT-Based Quantification of Prostate Volume Change After LHRH-Agonist Androgen Deprivation: A Prospective, Three-Reader Study for Radiotherapy Planning [PDF]

open access: yesLife
Introduction: ADT is routinely combined with radiotherapy (RT) for intermediate- and high-risk prostate cancer. While prostate shrinkage may facilitate planning, prospective CT-based, patient-level estimates over short, workflow-relevant intervals are ...

The prototype of EPID-based in vivo dose verification for VMAT treatments in patients with prostate cancer

open access: yesNowotwory, 2023
INTRODUCTION: The volumetric modulated arc therapy technique (VMAT) is now widely used in radiotherapy. Verifica­tion of the dose delivered to the patient is performed prior to the treatment (pre-treatment mode).

Robust radiotherapy planning [PDF]

open access: yesPhysics in Medicine & Biology, 2018
Motion and uncertainty in radiotherapy is traditionally handled via margins. The clinical target volume (CTV) is expanded to a larger planning target volume (PTV), which is irradiated to the prescribed dose. However, the PTV concept has several limitations, especially in proton therapy. Therefore, robust and probabilistic optimization methods have been
