Twenty-six cases of renal artery stenosis were evaluated with Doppler ultrasound using the pulsatile flow index (PFI). To establish normal values, the PFI in 60 renal arteries in 30 healthy volunteers was obtained. Normal values by PFI ranged between 0.48 and 0.71 (mean +/- SD: 0.6 +/- 0.06). In renal artery stenosis the PFI range was 0.72-0.79. The normal(More)
This paper describes a facial animation playback scheme based on simultaneous encoding of captured face textures and geometric positions. The high quality facial data is acquired using a more robust variant of the Universal Capture (UCap) technique that incorporates state-of-the-art marker-based motion capture. A novel encoding, based on Principal Component(More)
A case of sarcoidosis is reported, which began 25 years ago. As a late complication the patient developed compression syndrome of the superior caval vein, which was caused by swelling of the lymph nodes. After surgical treatment, which was carried out by removing the regional lymph nodes and implantation of a dacron prosthesis, stenosis occurred within the(More)
