The invention relates to a design and implementation method of a 4pi Compton camera based on a spherical array structure, and the method comprises the steps: giving a basic distribution structure of a detector array based on a spherical surface equalization algorithm, and simulating the imaging performance of the camera under different structural parameters through employing a Monte Carlo method; according to the performance parameters obtained through simulation, camera structure parameters with better performance are given, finally, based on the structure parameters obtained through optimization, a circuit design scheme of the Compton camera is given, and a complete Compton camera is formed in cooperation with matched software and a rear-end control system. The camera is based on a spherical array structure and has uniform angle response, and the Compton camera is structurally optimized according to the requirement for detection efficiency. 本发明涉及一种基于球形阵列结构的4π康普顿相机的设计与实现方法，所述方法基于球面均分算法给出探测器阵列的基础分布结构，采用蒙特卡洛方法
