AI Technical Summary

Technical Problem

Existing technologies using CT for SPECT attenuation correction suffer from mismatch issues, leading to imaging errors and additional radiation exposure, which increases equipment costs.

Method used

By acquiring multi-window scan data from single-photon emission computed tomography (SPECT), images of the main energy window and scattering window are reconstructed, attenuation coefficient images are calculated, and these are used to correct the main energy window images, thus avoiding the use of CT imaging.

Benefits of technology

It enables accurate attenuation correction without CT imaging, reducing equipment costs and radiation exposure, and improving imaging accuracy.
