Journal ArticleDOI
Dosimetric performance of the Elekta Unity MR-linac system: 2D and 3D dosimetry in anthropomorphic inhomogeneous geometry.
Evangelos Pappas,G. Kalaitzakis,T. Boursianis,E. Zoros,K. Zourari,Eleftherios P. Pappas,D. Makris,Ioannis Seimenis,Efstathios P. Efstathopoulos,Thomas G. Maris +9 more
TL;DR: This work presents a benchmarking methodology comprising 2D/3D passive dosimetry and involving on-couch adaptive treatment planning, a unique step in MR-linac workflows, suitable for QA procedures in Unity.
Journal ArticleDOI
Neural foundations of overt and covert actions.
Panagiotis G. Simos,Eleftherios Kavroulakis,Thomas G. Maris,Efrosini Papadaki,T. Boursianis,Giorgos Kalaitzakis,Helen E. Savaki,Helen E. Savaki +7 more
TL;DR: Functional connectivity analyses corroborated the notion that a common sensory‐motor fronto‐parieto‐temporal cortical network is engaged for execution, observation, and imagination of the very same action.
Journal ArticleDOI
3D polymer gel MRI dosimetry using a 2D haste, A 2D TSE AND A 2D SE multi echo (ME) T2 relaxometric sequences: Comparison of dosimetric results
Thomas G. Maris,Evangelos Pappas,T. Boursianis,G. Kalaitzakis,Nikos Papanikolaou,L. Watts,Michalis Mazonakis,John Damilakis +7 more
TL;DR: 2D-ME-HASTE sequences hold the absolute advantage of being a fast and the most reliable solution in VIPAR MRI gel dosimetry.
Journal ArticleDOI
Brain stereotactic radiosurgery using MR‐guided online adaptive planning for daily setup variation: An end‐to‐end test
Eun Young Han,He C Wang,Tina Marie Briere,Debra Nana Yeboa,T. Boursianis,G. Kalaitzakis,Evangelos Pappas,P. Castillo,Jinzhong Yang +8 more
TL;DR: An end‐to‐end test for brain SRS with multiple metastases treated with a 1.5‐Tesla MR‐Linac is performed and the ATS workflow achieved better dosimetric results than the ATP workflow at the cost of longer optimization time.
Optimising T2 relaxation measurements on MS patients utilising a multi-component tissue mimicking phantom and different fitting algorithms in T2 calculations
G. Kalaitzakis,Efrosini Papadaki,Eleftherios Kavroulakis,T. Boursianis,Konstantinos Marias,Thomas G. Maris +5 more
TL;DR: WL, NL and DENLF algorithms proved to be an excellent means for optimised measurements of T2 values on tissue mimicking phantoms, NWM, NAWM and demyelinating lesions of RRMS patients.
