摘要：
A multiwire proportional chamber (MWPC) radiation sensor for use in X-ray digital imaging systems is presented. The system consists of a 2-D MWPC radiation image sensor filled with Ar gas and standard NIM/CAMAC radiation position readout electronics. The X-ray image performance of the system is demonstrated using a test mask made of a copper sheet with letter-shaped holes cut out of it. Reconstructed images of the X-ray projection through several objects are also presented. The digital X-ray image system has submillimeter position resolution and the advantages of easy data manipulation and display of digitally stored data.
