Abstract

Improvement in the performance of SPECT cameras has been remarkable. A highly sophisticated SPECT camera, the VERTEX EPIC from ADAC Laboratories, USA, was installed at our institution. The VERTEX has variable angle dual detectors and provides a fully digitized signal, the first such camera in japan. To examine the characteristics of this camera, we investigated its basic performance. The results of our study indicated the performance of this camera was satisfactory for clinical use. Intrinsic uniformity was 1.85%, intrinsic resolution 3.13mm, FWHM of SPECT(VXHR)8.2mm, and visual resolution 6.0mm. The VERTEX EPIC can play a role in various examinations in the field of clinical nuclear.
