The usefulness of SwiftScan technology for bone scintigraphy using a novel anthropomorphic phantom

Abstract The aim of this study was to demonstrate the usefulness of SwiftScan with a low-energy high-resolution and sensitivity (LEHRS) collimator for bone scintigraphy using a novel bone phantom simulating the human body. SwiftScan planar image of lateral view was acquired in clinical condition; th...
