A New Method of The Light Irradiation Image by The Computed Radiography (Imaging Plate) System

Abstract

There are two method for the purpose of diagnosing medically by using gamma-ray light irradiation image.
One is to use of the scintillation camera for gamma-ray, the other is to use of the photostimulable luminescence point by the secondary excitation of the image plate (IP) system for X-ray.
The standpoint of the spatial resolution at the total medical image, using gamma-ray, the first can get the image on a short time, but the first is a poor image quality, and the second is good image quality, but the second can the image on a long time, becaus of insenstive to gamma-ray.
We report on the improvement for IP's week point by our proposal method, and by our clinical and quantative analysis data, to use the highly effecient IP (ST-III).
We make the improvement on the imaging time (from 30 minutes to 20 minutes), and the inprocessing time (from 33_??_50 minutes to 27 minutes) for a former method on an organnism.
We strongly believe that our convenience improvement method, and our clinical quantative analysis data can contribute to the wide application as well as the quality up for the clinical diagnosis to use gamma-ray.
