US Patent:

8089037, Jan 3, 2012
Filed:

Sep 16, 2009
Appl. No.:

12/561204
Inventors:

Matthias J. Schmand - Lenoir City TN, US
Dongming Hu - Knoxville TN, US
Ziad Burbar - Knoxville TN, US
Assignee:

Siemens Medical Solutions USA, Inc. - Malvern PA
International Classification:

H01L 27/00
US Classification:

2502081, 250238
Abstract:

A method, process and apparatus for compensating for changes to the gain of photo detectors in a nuclear imaging apparatus is disclosed. Specifically, embodiments detect positron annihilation event pulses using photo detectors. Changes to the gain of the photo detectors are compensated for by determining the relationship of a detected event pulse peak with a target event pulse peak. Based on the difference between these two peaks, a corrected gain is determined in a closed-loop control system. The corrected gain can be used to compensate for temperature changes that can affect the gain of the photo detectors.

US Patent:

8117142, Feb 14, 2012
Filed:

Oct 6, 2008
Appl. No.:

12/245802
Inventors:

Dongming Hu - Knoxville TN, US
Assignee:

Siemens Medical Solutions USA, Inc. - Malvern PA
International Classification:

G06E 1/00
G06E 3/00
G06F 15/18
G06G 7/00
US Classification:

706 16, 706 12, 706 15, 706 17, 706 18
Abstract:

The present invention provides a method of real-time crystal peak tracking for avalanche-photodiode (APD) detectors on positron emission tomography (PET) scanners that satisfies the need to compensate for the significant gain drifting due to thermal variations in APD detectors on PET scanners.

Increasing Edge Sensitivity In A Radiation Detector

US Patent:

8450692, May 28, 2013
Filed:

May 5, 2011
Appl. No.:

13/101367
Inventors:

Stefan B. Siegel - Knoxville TN, US
Dongming Hu - Knoxville TN, US
Assignee:

Siemens Medical Solutions USA, Inc. - Malvern PA
International Classification:

G01T 1/20
US Classification:

250362, 25037009, 2503701, 250366
Abstract:

An apparatus and method to increase the sensitivity at the edge of radiation detector blocks is disclosed herein. Reduced sensitivity can result from photons entering a first detector block, escaping, and scattering into an adjacent detector, thereby depositing energy into two detectors blocks. Energy lost into adjacent detector blocks can be compensated with energy detected in the adjacent detector block. This can be done, for example, by processing channels from multiple detector blocks with one Field Programmable Gated Array (FPGA) on one Event Process Module (EPM) board. This can enable summing energy of one detector block with energy from an adjacent detector block when the initial interaction occurs at the edge of the first detector block. This can result in a better estimate of the amount of energy associated with the initial photon being detected.

System And Method For Controlling The Size Of The Molten Pool In Laser-Based Additive Manufacturing
view source
US Patent:

6995334, Feb 7, 2006
Filed:

Aug 25, 2003
Appl. No.:

10/649927
Inventors:

Radovan Kovacevic - Plano TX, US
Dongming Hu - Knoxville TN, US
Michael E. Valant - Dallas TX, US
Assignee:

Southern Methodist University - Dallas TX
International Classification:

B23K 26/34
G06F 19/00
US Classification:

21912163, 21912164, 700166
Abstract:

According to one embodiment of the invention, a method for controlling the size of the molten pool in a laser based additive manufacturing process includes coaxially aligning an imaging device with a laser nozzle and imaging a molten pool, created by a laser, on a substrate with the imaging device. The method further includes comparing at least one characteristic of the molten pool with a respective characteristic of a target molten pool, and adjusting, in substantially real-time, a laser power of the laser based on the comparison in order to correlate the characteristic of the molten pool with the respective characteristic of the target molten pool.

Hybrid Manufacturing Apparatus

US Patent:

20200101662, Apr 2, 2020
Filed:

Oct 2, 2019
Appl. No.:

16/591410
Inventors:

Dongming Hu - Knoxville TN, US
International Classification:

B29C 64/209
B29C 64/245
B29C 64/30
B29C 64/277
Abstract:

A hybrid manufacturing apparatus utilizing both additive and subtractive manufacturing processes has a cutting mechanism, a magazine, and a deposition nozzle. A cutting mechanism engages and modifies material fed from a magazine, the finished material of this process to be positioned by a deposition nozzle. More specifically, the cutting mechanism provides a chamber supporting an inlet, an outlet, and at least one cutting head. The inlet receives fresh material, the cutting head is positioned within the chamber to create the desired contours in or on the material, and the material then exits the chamber via the outlet to be deposited according to instructions extracted from a digital model in a form of numerical control (NC) programming language. This model is natively subdivided into individual constructs each defining a set of values to guide creation of corresponding physical sections, and the placement thereof.

Motion Correction For Medical Imaging

US Patent:

20160358334, Dec 8, 2016
Filed:

Jun 6, 2016
Appl. No.:

15/174130
Inventors:

- Knoxville TN, US
Dongming Hu - Knoxville TN, US
Sang Hyeb Lee - Novato CA, US
International Classification:

G06T 7/00
G06T 5/40
Abstract:

Systems and methods for correcting motion during medical imaging involve using a detector to track annihilation photons produced by one of (i) external emitting sources placed onto a body of a person being imaged or (ii) an object of interest in the body. Motion information is generated based on the tracking. A motion-corrected image is formed from recorded image data, using the motion information.
