Classical or static transaxial tomography has now become a powerful tool in nuclear medicine [1–3]. However, the necessary limitation in the radioactive dose the patient is exposed to, leads to low statistical quality of the reconstructed slices. Thus, dynamic imaging appears to be very difficult due to the reduction of activity in each individual frame. We present a new four-dimensional process which works simultaneously in the space and time domain and enables time-resolved axial tomography, particularly, in cardiac gated dynamic studies.
