Luhr A, Wagenaar D, Eekers D, Glimelius L, Habraken S, Harrabi S, et al.
Phys Imaging Radiat Oncol
. 2025 Jan;
33():100692.
PMID: 39839817
Background And Purpose: In proton therapy, a relative biological effectiveness (RBE) of 1.1 is used to convert proton dose into an equivalent photon dose. However, RBE varies with tissue type,...

Romero-Exposito M, Sanchez-Nieto B, Riveira-Martin M, Azizi M, Gkavonatsiou A, Munoz I, et al.
Phys Med
. 2024 Dec;
129():104879.
PMID: 39718311
Purpose: To propose a methodology for integrating the out-of-field and imaging doses to the in-field dose received by radiotherapy (RT) patients. In addition, the impact of considering the total dose...

Buciuman N, Dasu A, Marcu L
Phys Med
. 2024 Jul;
123:103427.
PMID: 38959576
Background: Reirradiation of head and neck cancer (HNC) became more accessible in the last decade, owing to modern irradiation techniques which offer a reduction in treatment related toxicities. The aim...

Olovsson N, Wikstrom K, Flejmer A, Ahnesjo A, Dasu A
Phys Med
. 2024 Jun;
123:103396.
PMID: 38943799
Purpose: Respiratory motion and patient setup error both contribute to the dosimetric uncertainty in radiotherapy of lung tumors. Managing these uncertainties for free-breathing treatments is usually done by margin-based approaches...
5.
Trnkova P, Dasu A, Placidi L, Stock M, Toma-Dasu I, Brouwer C, et al.
Phys Med
. 2024 Jun;
123:103407.
PMID: 38906046
Purpose: To investigate the current practice patterns in image-guided particle therapy (IGPT) for cranio-spinal irradiation (CSI). Methods: A multi-institutional survey was distributed to European particle therapy centres to analyse all...

Grau C, Dasu A, Troost E, Haustermans K, Weber D, Langendijk J, et al.
Radiother Oncol
. 2024 Apr;
196:110293.
PMID: 38653379
The evidence for the value of particle therapy (PT) is still sparse. While randomized trials remain a cornerstone for robust comparisons with photon-based radiotherapy, data registries collecting real-world data can...

Edvardsson A, Gorgisyan J, Andersson K, Vallhagen Dahlgren C, Dasu A, Gram D, et al.
Phys Imaging Radiat Oncol
. 2024 Feb;
29:100555.
PMID: 38405431
Background And Purpose: Hippocampal-sparing (HS) is a method that can potentially reduce late cognitive complications for pediatric medulloblastoma (MB) patients treated with craniospinal proton therapy (PT). The aim of this...

Romero-Exposito M, Liszka M, Christou A, Toma-Dasu I, Dasu A
Med Phys
. 2023 Dec;
51(7):5099-5108.
PMID: 38112191
Background: Superficial targets require the use of the lowest energies within the available energy range in proton pencil-beam scanning (PBS) technique. However, the lower efficiency of the energy selection system...

Almhagen E, Dasu A, Johansson S, Traneus E, Ahnesjo A
Phys Med
. 2023 Nov;
115:103157.
PMID: 37939480
Purpose: To investigate the feasibility of dose painting by numbers (DPBN) with respect to robustness for proton therapy for head and neck cancers (HNC), and to study the influence of...

Zubatkina I, Toma-Dasu I, Dasu A, Levivier M, Tuleasca C, Ivanov P
Neurosurgery
. 2023 Sep;
94(2):423-430.
PMID: 37665222
Background And Objectives: Brain metastases (BM) develop in nearly half of the patients with advanced melanoma. The aim of this retrospective historical cohort study was to analyze radiological response of...
