title: Specifying dual-detector gamma cameras and associated computer systems.
abstract: Increasingly, dual-detector gamma cameras are being purchased as replacements for single-headed cameras. The improvement in sensitivity offered by a dual-detector device can be used in several ways: to shorten acquisition times, to improve signal-to-noise ratios, or to reduce administered doses. This paper focuses on the practical aspects of dual-headed devices and aims to provide some guidance for potential purchasers in the drawing up of an equipment specification.
