摘要
Abstract
Computed tomography(CT)is a non-invasive X-ray diagnostic technique that allows reconstructing cross sections of a patient's body.It provides detailed information about structure of organs and examining pathological changes sensitively.Since the first CT scan for clinical use in the 70 s,several improvements have led to the current configuration of modern ultra-fast,low dose CT scans.X-ray detector technology enables growing detection efficiency and fast response.Such developments are partly brought about by advances in X-ray detectors,which can by mainly sorted into two types:indirect conversion and di-rect conversion based on different working principle.Systems for high-resolution preclinical CT(or micro-CT)have also seen a considerable growth in the last two decades,taking advantage of the modern technology of X-ray detectors of different geometry and mechanism.This article aims at reviewing the milestones of the evolution of X-ray detector technology that have traced the development of CT and micro-CT.An outlook of the current and future trends on both two types of detection methods will be also given.关键词
