investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Evaluation of Venous Drainage Patterns for Skull Base Meningioma Surgery
The evaluation of venous drainage patterns prior to surgery for skull base meningioma is important owing to their deep location and the vulnerability of surrounding vascular structures. In recent years, the microsurgical skull base approach has matured as a surgical technique, making it an important option for reducing complications related to skull base meningioma surgery. In addition, knowled...
متن کاملEffect of skull shape approximations in Gamma Knife dose calculations
Doses in Leksell GammaPlan (Elekta, Stockholm, Sweden) are calculated for each shot by summing the contribution from the 201 radiation beams emitted by the Gamma Knife (Elekta), weighted for attenuation in the tissue traversed. The patient's head is modeled based on 24 skull measurements, from which the depth to the calculation point is determined for each beam. The limited number of measuremen...
متن کاملOutcomes of Gamma Knife Radiosurgery in Patients With Parasagittal Meningioma
Background & Aim: The treatment of Parasagittal Meningioma (PSM) is always a challenge, especially when the tumor has already invaded the critical structures like venous sinuses. This study aims at evaluating the outcomes of Gamma Knife Radiosurgery (GKRS) in patients with PSM. Methods and Materials/Patients: In this descriptive retrospective study, we reviewed the medical records of 61 patien...
متن کاملshort term outcomes of gamma knife radiosurgery for skull base meningiomas in iran
introduction: skull base meningiomas constitute a large proportion of the meningiomas, which are the most common benign brain tumors. the treatment of skull base meningiomas is specially challenging and controversial due to the proximity of these tumors to the vital brain structures. radiosurgery is now emerging as an efficient alternative treatment modality which involves the ablation of tumor...
