Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Recently  proposed a joint reconstruction approach for dynamic cardiac images from a gated acquisition in single photon emission computed tomography (SPECT), where the time evolution at each image pixel is regulated by a B-spline function. Such an approach was demonstrated to be very effective for coping with the greatly underdetermined nature of the problem. In this work  further develop this approach by investigating the use of an adaptive smoothing prior on the spline control points based on their contribution to the acquired data counts. The proposed approach is evaluated using a dynamic version of the 4D gated mathematical cardiac-torso (gMCAT) phantom to simulate a gated SPECT perfusion acquisition with Tc 99m  Teboroxime. Our results demonstrate that the use of the newly introduced prior can improve the accuracy of the reconstruction
