Few shots transfer learning for universal SPECT denoising across diverse acquisition protocols.

Accelerated Single Photon Emission Computed Tomography (SPECT) imaging, achieved by reducing either the number of projection angles or the acquisition time per angle, enhances clinical workflow efficiency but introduces elevated noise. Although deep learning-based methods promises to overcome this limitation, their practical application is hindered by the reliance on large datasets makes deve...
