Pre-operative planning and intra-operative computer interfaces for minimally invasive interventions were investigated with an active robot integrated with a CT scanner. To test the robotic system, a biopsy study was performed using a pig. For pre-operative planning, a virtual needle was superimposed on axial slices and multiplanar reformatted views in(More)
PURPOSE Modern CT departments with multiple scanner architectures can easily have hundreds of different protocols for different size patients and clinical requirements. Unless a systematic approach is taken to the optimization and quality assurance of these protocols, care to the patient in the form of image quality, dose, and clinical usability of the CT(More)
Sciatic nerve palsy (SNP) is one of the most distressing complications associated with total hip arthroplasty. The authors used corticosomatosensory evoked potential monitoring in 290 consecutive patients in an attempt to predict when SNP might occur and to prevent its occurrence by changing the position of the retractors and/or the operated limb in(More)
The use of continuous-flow left ventricular assist devices (LVAD) have markedly improved outcomes in patients with advanced heart failure (HF). The HeartWare LVAD is a miniaturized centrifugal pump implanted within the pericardial space. Implantable cardioverter-defibrillators (ICDs) are susceptible to oversensing of extracardiac signals (electromagnetic(More)
