We are developing an imaging system that achieves both high spatial resolution and low background, aiming to enable pharmacokinetic imaging that clearly distinguishes multiple radionuclides accumulated in small organs only a few millimeters in size of small animals. In this presentation, we report the results of imaging tests using the newly designed tungsten parallel-hole collimator, along with strategies for background reduction based on radiation simulations.
