Radioaerosol ventilation system 'radio vent'
Description
A simple reusable radioaerosol generator and delivery system name 'Radio Vent' has been designed in the Radioisotope Production Group at PINSTECH for lung ventilation studies. Radioactive tracer techniques are widely used in the diagnosis of pulmonary embolism by mismatch. Different radioactive gases, for example Xenon-133 (t12 5.28d, E 81 KeV) and Krypton-81m (t12 13S, E 191 KeV) have beed used for ventilation studies to complement perfusion studies with technetium-99 labelled macro-aggregated albumin. The working principle of the 'Radio Vent' is that the radioaerosol particles are produced by a high velocity air jet impinging directly on the surface of liquid. (orign./A.B.)
