WebApr 10, 2024 · For pinhole SPECT, all the PPDFs of MPH-SPECT systems have the same edge slope, which is determined by pinhole opening angle and collimator material. WebA pinhole collimatorconsists of a piece of dense material containing only a single hole, which typically has the shape of a double cone. First attempts to obtain SPECT images of rodents with a high resolution were based on use of pinhole collimators attached to convectional gamma cameras.
