[en] A new circular ring positron ECT system has been proposed, in which the detectors are mounted on a circular gantry with 'unequal-spacings' so as to provide the fine and uniform linear sampling during 3600 rotation of the gantry around its center. This paper presents an iterative method for searching the optimal detector arrangement, and clarifies sampling characteristics of the obtained arrangements with various parameters such as the number of detector, angular margin in arrangement, and some other parameters in the iterative method. It is concluded that, if the total angular margin is not smaller than the angle subtended by one detector unit, we can determine a detector arrangement having a satisfactory sampling characteristics suitable for the reconstruction tomography
