Abstract
The Imaging Silicon Pixel Array (ISPA)-tube is a position-sensitive hybrid
photon detector. Originally developed for high-energy physics purposes, it
has also been used for biomedical applications. Two kinds of ISPA-tube prot
otypes have been tested successfully in the field of gamma ray imaging. The
current developments aim at obtaining a detector dedicated to single-photo
n emission imaging. In this paper, we present the first use in a gamma came
ra of a new ISPA-tube prototype having an increased active input surface of
40 mm diameter and a de-magnifying electron optics. The quartz input windo
w of the tube is optically coupled to a 3.5 cm(2) YAIO(3):Ce detector array
with 0.6 mm(2) single elements. (C) 2000 Elsevier Science B.V. All rights
