3- Dimensional analysis of true fracture plane for the proper fixation on lateral humeral condyle fracture in children
… angle of Kirschner-wire insertion depending on 3D-CT analysis in pediatric lateral humeral condyle fracture. MATERIAL AND METHODS: 100 lateral condyle fractures and the 3D-CT results of 31 pediatric patients were collected from 2003 to 2007. Radiographic classification was done. The angle formed …

Defect detection using 3D computed tomography images and application on nuclear power plants
Tools used in nuclear power plant (NPP) inspection are required to be inspected before and after use on a reactor to check their integrity. To address the long duration required for manual inspection, non-destructive testing (NDT) can be implemented. In this thesis, a novel NDT framework is …

Three Dimensional CT based Virtual Patellar Resection in Female Patients undergoing Total Knee Replacement
… influenced by the accuracy of the patellar resection, with the resultant thickness and symmetry of the patella-implant composite Methods: We performed virtual patellar resection with digital software using 3D-CT scans of knees from 49 patients who underwent primary TKR at our hospital, comparing …

A Study of Imaging Techniques of 3-Dimennsional CT Diagnosis for Rib Fractures
Rib fracture is a common disease occurring in patients with blunt chest trauma and can cause variable complications. However, the sensitivity of simple chest X-ray for the diagnosis of rib fracture is not high and the use of axial CT images of multi-detector computed tomography make us to spend so …

Outflow Reconstruction using Cryopreserved Aortic Patch in Right Lobe Living Donor Liver Transplantation
INTRODUCTION: Living donor liver transplantation(LDLT) using the right lobe graft has widely been used to compensate for cadaveric organ shortage. To provide adequate functional volume in LDLT using the right lobe, a successful reconstruction of middle hepatic vein(MHV) is required. We describe …

Quantification of rock fabric through multi-scale image data analysis for enhanced rock typing and formation evaluation
… of minerals, pores, and saturating fluids) affects the estimation of petrophysical, mechanical, and compositional properties of sedimentary geological formations. Quantification of rock fabric and its integration with rock classification and formation evaluation efforts are critical for reliable …

Development of Five-dimensional Magnetic Resonance Imaging (5D-MRI) for Radiation Therapy
… radiotherapy treatment planning uses 2D X-ray or 3D CT images to assist the delineation of tumor volumes and OARs, often under free-breathing condition. In modern radiation therapy, four-dimensional (4D) imaging is the state-of-art technique for imaging respiratory motion of thoracic and abdominal …
