Research Abstract

A computed tomography (CT) to simultanously detect scattering x-ray, fluorescent x-ray and transmission x-ray was developed. The interaction between the object and x-ray generated the scattering x-ray, fluorescent x-ray and transmission x-ray. In clinical practise, only the transmission x-ray is used to diagnose the disease. In this experiment we developed new type of CT to detect all information of x-ray interaction with object. Experiment was performed at bending magnet beam line ARNE 5A in KEK.
1. Fluorescent x-ray CT image : Specific element as iodine was detected as presently used single photon emission CT.Minimal detectable dose was 50ng iodine by fan collimator fluorescent-CT system using large diameter germanium detector.
2. Scattering x-ray CT image : Incoherent x-ray (Compton) and coherent x-ray (Thomson) CT imaging was obtained in the phantom by multi-channel germanium detector. Thomson CT image can demonstrate the difference of elements such as oil, water, calcium and contrast material. Compton CT can demonstrate the differnce of electron density of material.
3. Transmission x-ray image : Using CCD detector, fine stracture of the phantom was revealed. Detectable concentration of iodine contrast material was 200 microgram/ml in 1 mm slice thickness.
A new type of CT to detect all information of x-ray interaction was developed and this system is thought to reveal various informations of object simultaniously.
