Filed:

Oct 30, 2007

Appl. No.:

11/929313

Inventors:

Rogerio Geraldes Rodrigues - Clifton Park NY, US

Assignee:

General Electric Company - Niskayuna NY

International Classification:

G01N 33/53

US Classification:

422 8201, 436518, 436524, 436806, 422 50

Abstract:

Embodiments of the present technique facilitate the detection of analytes. Detection is generally achieved by binding agents labeled with non-radiative energy transfer acceptors. The binding agents, when bound to a specific analyte, change conformation such that the distance between the respective non-radiative energy transfer acceptors and a respective quantum dot or quantum well changes. Certain embodiments of the present technique also comprise readout circuitry configured to determine rates of non-radiative energy transfer electrically and not optically.

International Classification:

G01T 1/24

US Classification:

250370140

Abstract:

In accordance with an implementation of the present technique, a detector is disclosed. The detector includes a photodetector array and a substrate layer. The photodetector array includes a plurality of photodiodes and a structure of trenches or diffusions grids that electrically isolate each photodiode of the plurality of photodiodes. The plurality of photodiodes and the structure of trenches or deep diffusions grids are disposed on a first surface of the photodetector array and a second surface opposite the first surface is bonded to a substrate layer. The substrate layer is typically made of the same semiconductor material as the photodetector array but heavily doped and conductive to provide cathode contact to the photodetector array in addition to mechanical support.

International Classification:

A61B 6/00

US Classification:

378 19, 378 988, 25037011

Abstract:

A detector module for a CT imaging system includes a scintillator to convert x-rays to optical photons. The scintillator is optically coupled to a solid-state photomultiplier with internal gain to receive the optical photons and convert them into a corresponding electrical signal output.
