Ferrous xylenol gel was evaluated as a dosimeter in verifications of treatment plans for
treatments of female breast tumors in external-beam radiation therapy. The dosimeter was …

The current work describes the investigation of film and gel samples, which combine poly
(vinyl alcohol)(PVA) and gelatin containing thymolphthalein dye (TP). Under the effect of …

Small-field radiotherapy is an emerging technique that offers the potential to reduce damage
to normal tissue, yet accurately measuring the dose distribution of small radiation fields …

In gel dosimetry applied to radiotherapy, the space–time corrections are necessary due to
the diffusion of ions in the oxidized solution dosimetry. Consequently, methodologies are …

Radiation therapy is an important modality for cancer treatment. Treatment machines are
divided into two types:(1) Radioactive sources (eg cobalt-60 machine) which deliver gamma …

The accuracy and precision are necessary factors in radiotherapy, especially for
measurements involving output factors and beam profiles; in this case multileaf collimators …

In radiation therapy, the shielding of normal tissue can be made using Cerrobend® blocks or
a multileaf collimator. In this work, profiles of shielded fields collimated by Cerrobend blocks …

The usage of dosimetry of small fields in radiotherapy to measure radiation dose is difficult
because of high-dose gradients, lateral electronic disequilibrium, and detector volume …

The small-field radiotherapy is a developing technique because it can reduce the damage to
normal tissues. However measurement of the dose distributions of small radiation fields in …

Os géis dosimétricos vêm sendo estudados para se tornarem mais sensíveis, a partir, das
modificações em suas concentrações de seus reagentes. No dosímetro Fricke padrão …
