The Aberdeen Mark II single-photon-emission tomographic scanner: specification and some clinical applications

Abstract

The construction, operation and physical characteristics of a single-section multi-detector single-photon-emission scanner are described. The machine has 24 detectors arranged along the sides of a square. Movements and data collection are under the control of a series of distributed microprocessors. Both head and trunk tomograms can be produced. The spatial resolution at the collimator focus is 9 mm in the transverse plane, and the effective slice thickness is 14 mm. The volume sensitivity is 300 counts/s kBq ml with a 20 cm diameter cylindrical phantom filled with 99Tcm solution. The application of this machine to the examination of the brain, liver and heart has been found to be clinically useful.

Neuro‐SPECT: On the development and function of brain emission tomography in the Copenhagen area

“…The first "Aberdeen Section Scanner" (Bowley et al, 1973) was a dual head-scanning device designed for combined use in planar and tomographic section scanning. A successor, the Aberdeen II, could also be used in both modes (Evans et al, 1986). This instrument combined a tangential and a rotational motion.…”

Measurement of Amount of Generated Acoustic Cavitation: Investigation of Spatial Distribution of Acoustic Cavitation Generation Using Broadband Integrated Voltage

“…At the beginning, it could not have been expected that the work of physicists in nuclear medicine-and later MRI-would lead to a step forward in the battle against mental disorders; a fulfilment of a medieval dream (figure 2). This scanner, and the improved version (Evans et al 1986), and the rotating gamma-camera version (Chesser and Gemmell 1982), built in Aberdeen through the mid-1970s, became the method of choice for brain tumour detection for some years.
