Method and device for converting analog signal into digital signal, computer equipment and medium

The invention relates to a method and device for converting analog signals into digital signals, computer equipment and a medium. The method comprises the following steps: acquiring analog signal data obtained by performing signal detection on a detection object by a detector array; the detection object is a medical diagnosis and treatment object into which a radioactive tracer agent is input; the detector array is used for three-dimensionally surrounding a detection object and detecting a tracing signal sent by the detection object to obtain analog signal data; respectively inputting the analog signal data into a plurality of signal converters so as to carry out parallel conversion processing on the analog signal data to obtain correspondingly converted multi-channel digital signal data; optimizing the multiple paths of digital signal data to obtain optimized digital signal data; the optimized digital signal data is used to construct a medical detection image for the detected object. By adopting the method,
