“…Thus the RSH is much less effected by the presence of scatter than the ~P H below depths of 10 cm and has a better depth resolution at all depths. The effect of scatter on the FWHM for the large ~P H and the effect of different pinhole sizes on depth FWHM, sensitivity and uniformity are given in Brookeman and Maisey (1982).…”

Two 7-pinhole tomographic imaging systems for large and small field-of-view gamma cameras were compared with a standard rotating slant-hole system in terms of planar resolution and resolution with depth. Other measurements include the determination of the depths of the reconstructed planes, image miniaturization and scintislice area variation with depth, the effect of scatter on resolution and the variation in resolution across the reconstructed plane. The pinhole sensitivities and the relative reconstructed sensitivities with depth were also measured. The rotating slant-hole system is found to have better depth resolution, a better scatter correction, has more uniform reconstructed sensitivities, is easier to position over the patient but requires significantly longer data acquisition times than the 7-pinhole system.

“…The particular heart phantom (the 'Iowa' or "Mueller' cardiac phantom) was chosen because it is easy to duplicate and because results could be compared with those published for 7-pinhole tomography (Williams et a1 1980) and conventional heart imaging (Mueller et a1 1976). Other aspects in the comparison of the different techniques have been covered in papers by Mullani et a1 (1981), Brookeman and Maisey (1982) and Ritchie et a1 (1982).…”

Measurements were made on the tomographic imaging abilities of a rotating slant hole collimator and a rotating scintillation camera system using a standard heart phantom and thallium-201. This allowed a comparison to be made between these and published results for conventional imaging and the seven pinhole technique under standardised conditions. Although better intraplanar resolutions were obtained with the rotating slant hole, the rotating camera was found to give superior definition of a defect and less propagation between reconstructed sections of the phantom.
