1. Gamma knife radiosurgery for trigeminal neuralgia: first case series from Latin America
RESUMO A radiocirurgia por Gamma Knife (GKRS) para neuralgia do trigêmeo é um tratamento comprovado, com redução de pelo menos 50% da dor em 75-95% dos casos. Objetivo: Apresentar a primeira série de pacientes tratados por neuralgia do trigêmeo com GKRS na America Latina. Métodos: Análise retrospectiva. A análise consistiu no tempo até melhora do

2. SPINE METASTASIS OF INTRACRANIAL HEMANGIOPERICYTOMA: CASE REPORT OF TWO TREATMENTS
RESUMO Objetivo: Reportar o uso de duas técnicas (radiocirurgia e vertebrectomia em bloco) no mesmo paciente, para o tratamento de metástases de um hemangiopericitoma intracraniano em dois locais da coluna. Hemangiopericitomas intracranianos são raros, consistindo em cerca de 2,4% dos tumores da meninge e menos de 1% de todos os tumores do sistema nervos

3. Spine radiosurgery for the local treatment of spine metastases: Intensity-modulated radiotherapy, image guidance, clinical aspects and future directions
Many cancer patients will develop spinal metastases. Local control is important for preventing neurologic compromise and to relieve pain. Stereotactic body radiotherapy or spinal radiosurgery is a new radiation therapy technique for spinal metastasis that can deliver a high dose of radiation to a tumor while minimizing the radiation delivered to healthy, nei

4. Aceite, comissionamento e controle de qualidade em radiocirurgia / Acceptance, commissioning and quality control in radiosurgery
A Radiocirurgia Estereotática é a técnica de tratamento que usa feixes estreitos de radiação focalizados com grande exatidão em uma lesão pequena. A introdução dos colimadores micro multi-lâminas (mMLC) permite que essa técnica alcance um maior grau de conformação de dose na lesão alvo, possibilitando uma menor irradiação das estruturas crít

5. Ferrous Xylenol Gel measurements for 6 and 10 MV photons in small field sizes
The Fricke dosimeter is a ferrous sulfate aqueous solution that, when irradiated, oxidizes the Fe2 + ions to Fe3 + . This new concentration, generally determined through spectrophotometry, is directly proportional to the ionizing radiation absorbed energy. The Fricke Xylenol Gel dosimeter (FXG) was developed through the incorporation of swine skin gelatin an

6. Características dosimétricas para campos pequenos, visando a implementação de um sistema postal de controle de qualidade na radiocirurgia / Small fields dosimetric characteristics for the radiosurgical quality control postal system implementation
Radiosurgery is a special technique indicated for small intracranial injuries treatment. For that, a high dose (>20 Gy) from 6 and 10 MV fotons is delivered into a small target volume. The scope of this work is to implement a Quality Control Postal System (QCP) in radiosurgery, in order to evaluate the absorbed dose delivered to the target volume [AAPM (1995

7. Stereotactic radiosurgery in the treatment of brain metastases: efficacy and complications based on brain location / Radiocirurgia no tratamento das metástases cerebrais: resposta terapêutica e complicações baseadas na localização da lesão
Brain metastases are the most common Central Nervous System tumors. Among the therapy options stereotactic radiosurgery has became in the last two decades an usefulness treatment technique attending with lower complication and mortality rate. However, even an extended literature review, many questions remain unclear about this therapy modality, mainly relate

8. "Fusão de imagens médicas para aplicação em sistemas de planejamento de tratamentos em radioterapia" / MEDICAL IMAGES FUSION FOR APPLICATION IN TREATMENT PLANNING SYSTEMS IN RADIOTHERAPY
Software for medical images fusion was developed for utilization in CAT3D radiotherapy and MNPS radiosurgery treatment planning systems. A mutual information maximization methodology was used to make the image registration of different modalities by measure of the statistical dependence between the voxels pairs. The alignment by references points makes an in

9. Stereotactic radiosurgery.
The development and scope of stereotactic radiosurgery is described. The technique, which combines well with the latest diagnostic methods, has already proved a safe and effective way of treating inaccessible cerebral lesions and in particular small arteriovenous malformations, acoustic neuroma and the solid component of craniopharyngioma, as well as playing

10. Stereotactic linac radiosurgery for arteriovenous malformations.
Stereotactic linear accelerator (linac) radiosurgery has been in operation in the West Midlands since 1987, the first of its kind in the United Kingdom. Forty two patients with high-flow cerebral arteriovenous malformations have been treated, 26 of whom have been followed up. Angiography one year after treatment showed that five lesions were obliterated, 11
