摘要：
PURPOSE: A method for imaging radiation is provided to reorganize images by using a detector with no self-resolution without using a collimator, thereby improving sensitivity and spatial resolution.CONSTITUTION: A method for imaging radiation comprises: a step(ST10) for obtaining projections with respect to each point around a target object a step(ST20) for calculating a system matrix which is a probability of distributed radiation sources in an image region contributing to the projections of each point and a step(ST30) for calculating the distribution of the radiation source by using the system matrix corresponding to the projections. In the step for obtaining the projections, two or more different valid view fields are generated by using one or more detectors for which the valid view field is controlled for the projections at each point by using the difference of the valid view fields.COPYRIGHT KIPO 2013[Reference numerals] (AA) Improved distribution of radiation sources obtained (ST10) Step of obtaining projections (ST20) Step of calculating a system matrix (ST30) Step of calculating the distribution of radiation sources (ST40) Step of removing noise본 발명은 방사선 영상화 방법에 관한 것으로서, 콜리메이터를 사용하지 않고 자체 해상도가 없는 검출기를 이용하여 영상 재구성할 수 있도록 함으로써 민감도와 공간분해능을 향상시켜 핵산업에 적용할 수 있고, 배열 형태로 확장하여 광역지역의 오염검사 또는 컨테이너 트럭 검색 등 검색 대상이 매우 넓거나 클 때 저비용으로 확대설치가 가능하고 고민감도의 시스템 구현이 가능하도록 하는 효과를 갖는다.
