Integrating 3D Rotational Angiography into Gamma Knife Planning

Simultaneous dual vessel cerebral angiography in gamma knife planning.

Gamma knife radiosurgery is an effective technique for treating arteriovenous malformations. However, treatment failures can occur as a result of incomplete visualization of the arteriovenous malformation nidus. We describe the use of bilateral femoral artery catheterization and simultaneous dual vessel cerebral angiography to facilitate treatment planning during gamma knife treatment.

Gamma Knife Dosimetry & Treatment Planning

Inverse treatment planning for Gamma Knife radiosurgery.

An inverse treatment planning system for Gamma Knife radiosurgery has been developed using nonlinear programming techniques. The system optimizes the shot sizes, locations, and weights for Gamma Knife treatments. In the patient's prescription, the user can specify both the maximum number of shots of radiation and a minimum isodose line that must surround the entire treatment volume. After satis...

Advanced Gamma Knife Treatment Planning of Epilepsy

Mesial temporal lobe epilepsy (MTLE) specifically consists of atrophy and gliosis within the limbic system and is the most frequent cause of medically intractable epilepsy in adults (2). Currently, the standard treatment for epilepsy is the use of anticonvulsants. Medically intractable cases may be treated with temporal lobectomy, consisting of removal of parts of the superior temporal gyrus, t...
