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...

Nursing perspective of gamma knife of treatment

Gamma knife is a new noninvasive method for treatment of patient with brain tumors. ‎Another name of this procedure is steriotatic radiosurgery.‎‏ ‏This computerized advanced ‎technique was implicated by a team including neurosurgeon, neuroradialogist, oncologist, and ‎a nurse. This method is used for treatment of certain brain tumors and lesions. The benefits are ‎l...

GammaPlan-Leksell Gamma Knife radiosurgery treatment planning verification method.

This work provides a method for an independent check of Gamma Knife GammaPlan radiosurgery calculations, named the spherical approximation method or SAM. Based on skull dimension measurements, the treated volume of the head is modeled as a sphere of radius R. With this approximation, an analytical solution for fast ray tracing of the path length, for each of the 201 beamlets, of the Gamma Knife...
