TL;DR: The objectives are to reduce the radioactive dose given to the patient and to preserve or improve SNR, resolution and capturing time while incorporating three-dimensional capabilities in existing gamma imaging systems, based on super-resolved time-multiplexing methods using both variable and moving pinhole arrays.

Time Multiplexed Pinholes Array based Imaging in the Gamma and X-ray Spectral Range
Ariel Schwarz,Amir Shemer,Rachel Bar-Shalom,Hemy Avraham,Nisan Ozana,Hadar Pinhas,Zeev Zalevsky +6 more
TL;DR: In this article, the authors validate and optimize a lensless radiation imaging technique for gamma and x-ray systems based on variable coded aperture, which can also provide depth information and 3D images with improved SNR and sensitivity.
