The Design and Characterization of a Multiple Pinhole Collimator and Its Applications in Biopharmaceutics
Abstract
dc:descriptionA 4-pinhole collimator was designed to image small objects and its characteristics were studied. The field of view formed by this collimator was a conically-tipped pyramid with a minimum object distance of 3 cm. The line-spread function at 8 cm from the collimator had a full-width-half-maximum of 8.5 mm and the depth resolution was 2 cm at 7.5 cm from the collimator. The geometric distortion of images caused by multi-pinhole collimation was also investigated. It was concluded that tablet disintegration can only be discerned from visual images under favorable conditions such as short source-to-collimator distances and parallelism of the planes of the object and the collimator.
