Annually 133.000 people world-wide get sick on malign melanoma, tendency increasing. The purpose of this study is the early diagnosis malignant skin cancer. At moment dermatologists are screening for anomalies at relevant lesion by examining area with a microscope. To determine changes, another scan has to be taken in follow-up session after time period about 15-20 weeks. Today's visual diagnostic decision based pragmatic ABCD-approach (Asymmetry, Border, Colour, and Diameter). However,...
Twenty-three femurs (one plastic bone and twenty-two cadaver bones) with both nonpathologic pathologic cases were considered to validate a statistical shape model based technique for three-dimensional (3D) reconstruction of patient-specific surface from calibrated x-ray radiographs. The 3D is on an iterative nonrigid registration the features extracted statistically instantiated those interactively identified models reconstructed radiographs compared associated ground truths derived either...
Modern computerized planning tools for periacetabular osteotomy (PAO) use either morphology-based or biomechanics-based methods. The latter relies on estimation of peak contact pressures and areas using patient specific constant thickness cartilage models. We performed a finite element analysis investigating the optimal reorientation acetabulum in PAO surgery based simulated joint model. Furthermore we investigated influences model biomechanical simulation results. Ten specimens with hip...
Purpose: To quantify the deformations of femoropopliteal (FP) segment in patients undergoing endovascular revascularization and to compare posttreatment caused by primary nitinol stent implantation those produced percutaneous transluminal angioplasty (PTA). Methods: Thirty-five (mean age 69±10 years; 20 men) scheduled for therapy were recruited study. During interventions, angiographic images acquired with legs straight a hip/knee flexion 20°/70°. Image acquisition was performed before PTA...
In this paper, we present a novel C-arm calibration approach for orthopedic applications that is based on distortion correction plate with fiducials arranged in single-plane and mobile phantom. The former designed to be rigidly attached the image intensifier used together statistical model of geometrical pattern intra-operative correction. latter can placed anywhere close patient anatomy being imaged. A simulation method then proposed robust detection phantom from an intra-operatively...
Goal: In the following, we will present a newly developed X-ray calibration phantom and its integration for 2-D/3-D pelvis reconstruction subsequent automatic cup planning. Two different planning strategies were applied evaluated with clinical data. Methods: methods investigated: The first strategy is based on combined statistical atlas. Thereby, part of atlas matched to reconstructed model, resulting in an optimized second analyzes morphology model determine best fitting implant. Results:...
