This work proposes a new method for pseudo-3D verification of intensity-modulated radiation therapy (IMRT) dose distributions. Unlike commercial solutions, it uses measured doses only for gamma evaluation. Its resolution is far better than with electronic detectors within the measured plane and comparable in other directions. It is readily available at clinics because it uses existing resources-a slab phantom and EBT3 films. The method was tested on six IMRT clinical cases. An in-house code for 2D and pseudo-3D gamma analysis was written in MATLAB and compared to OmniPro I'mRT.

Sekundární mozkové nádory, mozkové metastázy, se vyskytují až u 30–40 % všech onkologických pacientů se solidními nádory, přičemž riziko jejich výskytu a incidence nadále narůstá. Cílem tohoto přehledového článku je poskytnout základní a zároveň aktuální informace o současných možnostech radioterapie pacientů s mozkovými metastázami. V poslední době bylo publikováno několik velkých randomizovaných studií potenciálně ovlivňujících denní praxi v léčbě zářením. Snahou je, v souladu se zaměřením časopisu, poskytnout didakticky a prakticky podané informace o problematice sekundárních mozkových nádorů s důrazem na jejich využitelnost v denní klinické praxi.
Secondary brain tumors, brain metastases, develop in up to 30–40 % of all solid tumor cancer patients, with increasing incidence. The aim of this review is to provide both basic as well as current information on up-to-date treatment options for patients with brain metastases. The aim is, in accordance with the focus of the journal, to provide didactical and practical information on the issue of radiotherapy of secondary brain tumors with an emphasis on their usefulness in daily clinical practice. Several large randomized trials potentially affecting daily practice have recently been published and are discussed in this review.
