Introduction
Radiotherapy is an effective local treatment option in patients with hepatocellular carcinoma (HCC). However, photon radiotherapy is not a widely used modality in HCC as most patients have underlying cirrhosis making the liver more sensitive to radiation induced liver disease (RILD).
The aim of this national phase II study (NCT05203120) is to investigate feasibility and safety...
The aim of the Danish randomized HERAN2 trial is to examine if heterogeneous and hypofractionated proton radiotherapy can improve survival compared with X-ray radiotherapy in patients with locally advanced NSCLC who are not candidates for standard chemoradiotherapy. Patients selected for proton therapy are treated at the Danish Center for Particle Therapy and hereby, we present our treatment...
The interplay between the beam delivery time structure and the patient motion makes 4D dose calculation (4DDC) important when treating moving tumors with IMPT. In a conventional 4DDC, each spot is assigned to its nearest phase image in a 4DCT, based on a delivery log and a breathing signal. The doses computed on the phase images are then deformed to a reference phase and accumulated. An...
In radiotherapy, forecasting the motion of a lung tumor is a fundamental task for dose delivery. Indeed, anticipating the motion saves time in the decision-making process for real-time applications and could lead to a better homogeneous dose delivery and more healthy tissues spared. Our method is trained and tested on fluoroscopic sequences generated from 4D-Computed Tomography (4DCT) scans...
[Purpose] kV-CBCT imaging during MV beam irradiation technique has been developed on C-arm linac. The purpose of this study was to quantify the performance of the intra-irradiation imaging technique under a phase-gated condition.
[Method] TrueBeam Developer mode was used to perform the intra-irradiation imaging. Catphan504 phantom was used. To demonstrate respiratory movement, the phantom was...
Background
Proton therapy for breast cancer is usually given in free breathing (FB). With the use of deep inspiration breath-hold (DIBH) technique, the location of the heart is shifted more caudally, away from the internal mammary nodes (IMN) and, thus, the dose to the heart could potentially be reduced. The aim of this study was to compare proton therapy in FB with proton therapy in DIBH for...
