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...
متن کاملGamma Knife Neurosurgery – a Review
Gamma Knife radiosurgery has an established therapeutic role in neurosurgery with around 250,000 cases treated and a follow up over 20 years. The success and control rates have improved as more experience of appropriate dosage has been gained and as more planning accuracy has been achieved by new machines, new computer programs and better quality control. The currently quoted control rates for ...
متن کاملGammaPlan-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...
متن کاملAcute Hemorrhage Following Gamma Knife Radiosurgery to a Clival Meningioma.
BACKGROUND Gamma Knife radiosurgery (GKS) is a primary treatment modality for small, surgically-challenging meningiomas of the skull base in carefully selected patients. Despite the overall low incidence of complications from this procedure, rare instances of hemorrhagic events following GKS have been reported. In fact, only a single, probable case of acute hemorrhage after GKS for a meningioma...
متن کاملA new Gamma Knife radiosurgery paradigm: tomosurgery.
This study proposes and simulates an inverse treatment planning and a continuous dose delivery approach for the Leksell Gamma Knife (LGK, Elekta, Stockholm, Sweden) which we refer to as "Tomosurgery." Tomosurgery uses an isocenter that moves within the irradiation field to continuously deliver the prescribed radiation dose in a raster-scanning format, slice by slice, within an intracranial lesi...
