Early dedicated detectors replaced the single NaI scintillating crystal of conventional gamma cameras with pixelated arrays of cesium iodide (CsI) or NaI coupled to position-sensitive photomultiplier tubes (PSPMTs). Other designs have comprised multi-crystal arrays of CsI coupled to solid-state silicon photodiodes.
