Depauw N, Kooy H, Daartz J, Bussiere M, Batin E, Madden T, et al.
Biomed Phys Eng Express
. 2022 Feb;
8(2).
PMID: 35158343
The use of field-specific apertures, routine in scattered or uniform-scanned proton fields, are still a necessity in pencil-beam scanned (PBS) fields to sharpen the penumbral edge at low energies and...

Hamming-Vrieze O, Depauw N, Craft D, Chan A, Rasch C, Verheij M, et al.
Phys Med Biol
. 2019 Mar;
64(9):095001.
PMID: 30921775
Setup and range uncertainties compromise radiotherapy plan robustness. We introduce a method to evaluate the clinical effect of these uncertainties on the population using tumor control probability (TCP) and normal...

Kraan A, Depauw N, Clasie B, Madden T, Kooy H
Phys Med
. 2019 Feb;
57:58-64.
PMID: 30738532
Background: In scanned proton beam therapy systematic deviations in spot size at iso-center can occur as a result of changes in the beam-line optics. There is currently no general guideline...

Kooy H, Grassberger C
Br J Radiol
. 2015 Jun;
88(1051):20150195.
PMID: 26084352
Intensity modulated proton therapy (IMPT) implies the electromagnetic spatial control of well-circumscribed "pencil beams" of protons of variable energy and intensity. Proton pencil beams take advantage of the charged-particle Bragg...

van de Water S, Kraan A, Breedveld S, Schillemans W, Teguh D, Kooy H, et al.
Phys Med Biol
. 2013 Sep;
58(19):6969-83.
PMID: 24029721
This study investigates whether 'pencil beam resampling', i.e. iterative selection and weight optimization of randomly placed pencil beams (PBs), reduces optimization time and improves plan quality for multi-criteria optimization in...

Engelsman M, Lu H, Herrup D, Bussiere M, Kooy H
Med Phys
. 2009 Jul;
36(6):2172-80.
PMID: 19610306
Proton radiotherapy centers that currently use passively scattered proton beams do field specific calibrations for a non-negligible fraction of treatment fields, which is time and resource consuming. Our improved understanding...

Daartz J, Bangert M, Bussiere M, Engelsman M, Kooy H
Med Phys
. 2009 Jun;
36(5):1886-94.
PMID: 19544808
A mini-multileaf collimator (MMLC) was mounted as a field shaping collimator in a proton beamline at the Massachusetts General Hospital. The purpose is to evaluate the device's dosimetric and mechanical...

Paganetti H, Jiang H, Lee S, Kooy H
Med Phys
. 2004 Aug;
31(7):2107-18.
PMID: 15305464
Monte Carlo dosimetry calculations are essential methods in radiation therapy. To take full advantage of this tool, the beam delivery system has to be simulated in detail and the initial...

St Clair W, Adams J, Bues M, Fullerton B, La Shell S, Kooy H, et al.
Int J Radiat Oncol Biol Phys
. 2004 Feb;
58(3):727-34.
PMID: 14967427
Purpose: To compare treatment plans from standard photon therapy to intensity modulated X-rays (IMRT) and protons for craniospinal axis irradiation and posterior fossa boost in a patient with medulloblastoma. Methods:...

Zissiadis Y, Dutton S, Kieran M, Goumnerova L, Scott R, Kooy H, et al.
Int J Radiat Oncol Biol Phys
. 2001 Aug;
51(1):108-12.
PMID: 11516859
Purpose: Intracranial germ cell tumors are rare, radiosensitive tumors seen most commonly in the second and third decades of life. Radiotherapy alone has been the primary treatment modality for germinomas,...
