Protective Efficacy of Different Ocular Radiation Protection Devices: A Phantom Study.

Purpose: The aim of this study was to investigate the efficacy of different designs and types of ocular radiation protection devices depending on simulated varied body heights in a phantom-simulated thoracic intervention.

Materials And Methods: A clinical angiography system with a standardized fluoroscopy protocol with an anthropomorphic chest phantom as a scattering object and optically stimulated luminescence dosimeters for measuring radiation dose were used. The dosimeters were placed at the position of eyes of an anthropomorphic head phantom simulating the examiner.

There are no guidelines for the use of heparin in the prophylaxis of deep vein thrombosis in outpatients. In a prospective clinical investigation in 1996 and 1997, 1321 outpatients after trauma of the lower extremities were screened by duplex-color-coded-ultrasound in order to detect deep vein thrombosis. There were two separate groups: group A with drug prophylaxis of deep vein thrombosis (n = 723) and group B (n = 598) without.
