Publication number: 20120062873Abstract: A system and method to provide a diagnosis of the breast disease state of a test breast sample. A database containing a plurality of reference SWIR data sets is provided where each reference SWIR data set has an associated known breast sample and an associated known breast disease state. A test breast sample is irradiated with substantially monochromatic light to generate scattered photons resulting in a test SWIR data set. The test SWIR data set is compared to the plurality of reference SWIR data sets using a chemometric technique. Based on the comparison, a diagnosis of a breast disease state of the test breast sample is provided. The breast disease state includes invasive ductal carcinoma or invasive lobular carcinoma disease state.Type: ApplicationFiled: June 6, 2011Publication date: March 15, 2012Applicant: Chemimage CorporationInventors: Shona Stewart, John Maier, Jeffrey Cohen

Publication number: 20120064564Abstract: A microplate reader and method has at least one measuring device and a holding device for accommodating at least one microplate and for positioning samples-containing wells of microplates in relation to the measuring device. The at least one measuring device is used for detecting light emitted by samples in wells of a microplate and/or which is influenced by samples transilluminated by light in the wells. The microplate reader has a control unit for controlling the composition of a gas atmosphere surrounding the wells containing the samples. A respective use is characterized particularly in that living cells are measured in a controlled gas atmosphere, wherein the living cells are chosen from microaerophilic, optionally anaerobic and obligatorily anaerobic microorganisms as well as fungi and eukaryotic cells.Type: ApplicationFiled: September 8, 2011Publication date: March 15, 2012Inventors: JOSEF GRASSL, Gerald Probst, Markus Schürf

Publication number: 20120062874Abstract: A system and method for locating and identifying unknown samples. A targeting mode may be utilized to scan regions of interest for potential unknown materials. This targeting mode may interrogate regions of interest using SWIR and/or fluorescence spectroscopic and imaging techniques. Unknown samples detected in regions of interest may be further interrogated using a combination of Raman and LIBS techniques to identify the unknown samples. Structured illumination may be used to interrogate an unknown sample. Data sets generated during interrogation may be compared to a reference database comprising a plurality of reference data sets, each associated with a known material. The system and method may be used to identify a variety of materials including: biological, chemical, explosive, hazardous, concealment, and non-hazardous materials.Type: ApplicationFiled: August 15, 2011Publication date: March 15, 2012Applicant: ChemImage CorporationInventors: Jeffrey Beckstead, Patrick Treado, Matthew Nelson
