Portable industrial limited angle gamma-ray tomography scanning system

摘要

Provided is a diagnostic method and system capable of applying tomography to industrial long cylindrical process systems, such as a pipe line, which are difficult to diagnose using existing medical or industrial computed tomography (CT) scanners. Existing industrial X-ray CT scanners cannot be used for such a pipe that is attached to the process system and thus cannot be placed on the turntable, and existing image diagnostic apparatuses of a fan beam type, a collimated beam type, etc. having a stereotyped structure are next to impossible to move and use for undetachable process systems and their peripheral devices. To solve these problems, there is provided a gamma-ray tomography scanning system that is capable of being directly attached to a pipe in operation and measuring a cross section of the pipe.

1. A portable industrial limited angle gamma-ray tomography scanning system comprising:
a scanning part for tomography scanning; and a clamping part for attaching the scanning part to an object to be measured, an image reconstructing part for performing cross-sectional reconstruction using an image reconstruction program to perform cross-sectional reconstruction of limited angle data on the basis of measured data, wherein the scanning part includes: a source assembly generating radiation of gamma-ray; a driving device rotating the source assembly; and a detector assembly detecting the radiation generated from the radiation source, and the source assembly includes: a source moving slide comprises two parts, a first part being disposed along a base plate having a C-shaped structure and a second part being detachable from the first part and filling an open part of the base plate; a source moving track that is coupled to the source moving slide; and a source collimator that is coupled to the source moving track, wherein said two parts of the source moving slide forms a closed circular structure.
