Title:
DETECTOR SYSTEMS FOR IMAGING
Document Type and Number:
WIPO Patent Application WO/2023/092333
Kind Code:
A1
Abstract:
Detector systems may include a plurality of edge-on detector modules (200, 300, 400A, 400B, 400C, 500, 600, 700, 800, 900). Each edge-on detector module (200, 300, 400A, 400B, 400C, 500, 600, 700, 800, 900) may include: a silicon substrate (210, 310, 410, 510, 610, 710, 810, 910) including a front side corresponding to a first side of the each edge-on detector module and a rear side corresponding to a second side of the each edge-on detector module (200, 300, 400A, 400B, 400C, 500, 600, 700, 800, 900); a plurality of detection elements (220, 320, 420, 520, 620, 720, 820, 920) disposed on the front side of the silicon substrate (210, 310, 410, 510, 610, 710, 810, 910); a backside electrode (330, 430, 530, 630, 730, 830, 930) disposed on the rear side of the silicon substrate (210, 310, 410, 510, 610, 710, 810, 910); and/or an anti-scatter structure (440, 450, 540, 640, 760, 770, 940, 950, 970) disposed on at least one of the first side or the second side of the each edge-on detector module (200, 300, 400A, 400B, 400C, 500, 600, 700, 800, 900), the anti-scatter structure (440, 450, 540, 640, 760, 770, 940, 950, 970) being configured to prevent or reduce scattering of photons emitted into the silicon substrate. The silicon substrate (210, 310, 410, 510, 610, 710, 810, 910), the plurality of detection elements (220, 320, 420, 520, 620, 720, 820, 920), the backside electrode (330, 430, 530, 630, 730, 830, 930), and/or the anti-scatter structure (440, 450, 540, 640, 760, 770, 940, 950, 970) may be configured as an integral piece.
