[Historical overview and the current practice of intracavitary treatment of cervical and endometrial cancer in the Oncoradiology Center of Budapest].

The aims of our study were to describe the history and development of intracavitary brachytherapy in the treatment of gynecological tumors, to introduce our current practice for intracavitary brachytherapy treatments based on CT planning. Gynecological intracavitary brachytherapy has been applied in our department since the early 1930s. After a long development it has been completely renewed by 2014.

Verification of quality parameters for portal images in radiotherapy.

Background: The purpose of the study was to verify different values of quality parameters of portal images in radiotherapy.

Materials And Methods: We investigated image qualities of different field verification systems. Four EPIDs (Siemens OptiVue500aSi(®), Siemens BeamView Plus(®), Elekta iView(®) and Varian PortalVision™) were investigated with the PTW EPID QC PHANTOM(®) and compared with two portal film systems (Kodak X-OMAT(®) cassette with Kodak X-OMAT V(®) film and Kodak EC-L Lightweight(®) cassette with Kodak Portal Localisation ReadyPack(®) film).

[Quality control of computed tomography scanners from the viewpoint of radiotherapy planning in Hungary].

The aim of this publication is to review the requirements necessary for using computed tomography (CT) for radiotherapy treatment planning. The equipments were tested with different CT phantoms. The authors made several measurements for checking the CT number, the quality and the mechanical parameters of CT tables.

[PET/CT based radiotherapy treatment planning in head and neck cancers].

The purpose of this study was to evaluate the experiences of PET/CT based radiation planning in patients suffering from head and neck cancer. PET/CT based 3D-conformal irradiation was used in eleven patients between March 2008 and February 2009. In six of the eleven cases the therapeutic plan was modified after PET/CT examination, as the previously determined lymph node negative state proved to be lymph node positive.
