Fig. 6From: Multiple-pinhole collimators improve intra- and between-rater agreement and the certainty of the visual interpretation in dopamine transporter SPECTCount sensitivity profiles. System count sensitivity profile of the triple-head SPECT system with the MPH collimators in axial direction (z-direction) and in radial (transaxial) direction compared to the uniform system sensitivity of the SPECT system in double-head mode with LEHRHS collimators. The radial sensitivity profile was measured at the maximum of the axial profileBack to article page
