The ease and success of a surgical procedure is significantly dictated by the pre-operative planning, type and placement of an incision and surgical approach along with positioning of the patient. The ultimate goal of incision and approach is adequate exposure of ‘area of interest’ along with optimal healing, cosmesis and functional outcome. Some of the general principles which should be follow...

Background/PurposeThis study determines and compares the geometric setup errors between stereoscopic x-ray kilo-voltage cone beam CT (CBCT) in phantom tests on a linear accelerator (linac) for image-guided (IG) stereotactic radiotherapy of intracranial tumors. Additionally, dose-volume metrics target volumes CBCT were evaluated.Materials/MethodsA Winston-Lutz- an anthropomorphic used. The mean ...

background: while various radiographic parameters and application of manual/gravity stress have been proposed to elucidate instability for weber b fibula fractures, the prognostic capability of these modalities remains unclear. determination of anatomic positioning of the mortise is paramount. we propose a novel view, the gravity reduction view (grv), which helps elucidate non-anatomic position...

Introduction: A new method based on image registration technique and an intelligent correlation model to calculate. The present study aimed to propose inter- and intra-fraction motion errors in order to address the limitations of conventional Patient positioning methods. Material and Methods: The configuration of the markerless method wa...
