Journal ArticleDOI
Adaptive radiotherapy for prostate cancer using kilovoltage cone-beam computed tomography: first clinical results.
Jasper Nijkamp,Floris J. Pos,T. Nuver,Rianne de Jong,Peter Remeijer,Jan-Jakob Sonke,Joos V. Lebesque +6 more
TL;DR: The diet and laxatives improved the image quality and tended to reduce prostate motion and the reduction in irradiated volume led to a significant reduction in the dose to the rectum.
Journal ArticleDOI
Radiation pneumonitis in patients treated for malignant pulmonary lesions with hypofractionated radiation therapy
Gerben R. Borst,Masayori Ishikawa,Jasper Nijkamp,Michael Hauptmann,Hiroki Shirato,Rikiya Onimaru,Michel M. van den Heuvel,José Belderbos,Joos V. Lebesque,Jan-Jakob Sonke +9 more
TL;DR: A significant dose-response relationship for RP was found after SBRT, which was not significantly different from the dose- response relationship for CFRT, although statistical analysis was hampered by the low number of patients in the high dose range.

TL;DR: In this paper, the authors evaluated the relationship between the mean lung dose (MLD) and the incidence of radiation pneumonitis (RP) after stereotactic body radiation therapy (SBRT), and compared this with conventional fractionated radiation therapy(CFRT).
Journal ArticleDOI
Breast patient setup error assessment: comparison of electronic portal image devices and cone-beam computed tomography matching results.
Rajko Topolnjak,Jan-Jakob Sonke,Jasper Nijkamp,Coen R.N. Rasch,D. Minkema,Peter Remeijer,Corine van Vliet-Vroegindeweij +6 more
TL;DR: Phantom measurements showed that CBCT accurately measures setup error whereas EPID underestimates setup errors in the cranial-caudal direction, and using CBCT decreased setup uncertainties significantly.
Journal ArticleDOI
3D in vivo dose verification of entire hypo-fractionated IMRT treatments using an EPID and cone-beam CT.
L. N. McDermott,M. Wendling,Jasper Nijkamp,Anton Mans,Jan-Jakob Sonke,Ben J. Mijnheer,Marcel van Herk +6 more
TL;DR: Back-projected EPID-based 3D in vivo dosimetry and cone-beam CT data can provide a safety net for advanced treatments involving dose escalation, as well as a full account of the delivered dose to specific volumes, allowing adaptation of the treatment from the original plan if necessary.
