The structural failure of a multi-hole collimator.

abstract：OBJECTIVE:Assessing the relative function of each of the three kidneys using nuclear scintigraphy with standard planar imaging in patients having undergone kidney transplant is problematic because of the different photon-attenuation factors associated with native versus transplanted kidneys. To address this, we applied...
