According to the embodiments of the present disclosure, since the known full-energy peak energy of the target nuclide is a value determined before the correction, it is possible to mark an energy coordinate of each full-energy peak in the channel address-energy coordinate system by combining the channel address corresponding to each full-energy peak information in the target interval, and thus a plurality of coordinate points with respect to the full-energy peak information may be obtained.
According to the embodiments of the present disclosure, since the target coefficient has been determined, other coefficients in the initial energy channel address function may be calculated according to the plurality of coordinate points drawn in the channel address-energy coordinate system as shown in

In some embodiments, the quadratic term coefficient c2 of the energy-channel address calibration function is generally close to 0, the value of the constant term coefficient c0 is also around 0, and the two hardly change with external conditions. Therefore, in the process of calculating the target coefficient of the present disclosure, the energy calibration function may be approximately expressed as Equation (3).
According to the embodiments of the present disclosure, after the target coefficient is determined, the constant term coefficient and the quadratic term coefficient in Equation (2) may be calculated by using the channel address-energy coordinate system, and the target energy channel address function may be obtained finally.
