An example comprises a housing with inlet openings and thermistors, in particular NTCs, arranged in the region of the inlet openings. The fire detector comprises a control unit connected to the thermistors for capturing temperature measurement signals.

Reasons for the absence of thermal fluctuations may be contamination in the region of the inlet openings or because the inlet openings are covered by a protective hood or by an adhesive tape.

Abstract: For larger FOV in a gamma camera, multiple solid-state detectors are tiled. The edge pixels of the pixelated detectors are smaller than interior pixels so that the pitch of the pixels or anodes is constant across the tiled detectors. The constant pitch occurs where pairs of edge pixels combined from different detectors contribute the pitch or area of an interior pixel. As a result of this optimized edge pixel pairing and corresponding regular pitch across the tiles, the spectral and other performance is less degraded.
