Cytological methods for detecting a disease condition such as malignancy by Raman spectroscopic imaging

InactiveUS20060281068A1Superior resolution and intensitySensitive assessmentRadiation pyrometryMicrobiological testing/measurementEpitheliumCancer cell
Raman molecular imaging (RMI) is used to detect mammalian cells of a particular phenotype. For example the disclosure includes the use of RMI to differentiate between normal and diseased cells or tissues, e.g., cancer cells as well as in determining the grade of said cancer cells. In a preferred embodiment benign and malignant lesions of bladder and other tissues can be distinguished, including epithelial tissues such as lung, prostate, kidney, breast, and colon, and non-epithelial tissues, such as bone marrow and brain. Raman scattering data relevant to the disease state of cells or tissue can be combined with visual image data to produce hybrid images which depict both a magnified view of the cellular structures and information relating to the disease state of the individual cells in the field of view. Also, RMI techniques may be combined with visual image data and validated with other detection methods to produce confirm the matter obtained by RMI.

InactiveUS20070178067A1Superior resolution and intensitySensitive assessmentBiocideGenetic material ingredientsBiological StressData set
A method and system of differentially manipulating cells where the cells, suspended in a fluid, are irradiated with substantially monochromatic light. A Raman data set is obtained from the irradiated cells and where the data set is characteristic of a disease status. The data set is assessed to identify diseased cells. A Raman chemical image of the irradiated cells is also obtained. Based on the assessment and the Raman chemical image, the fluid in which the cells are suspended is differentially manipulated. The diseased cells are directed to a first location and other non-diseased cells are directed to a second location as part of the differential manipulation. The diseased cells may be treated with a physical stress, a chemical stress, and a biological stress and then returned to a patient from whom the diseased cells were obtained prior to the irradiation.

An atmospheric pressure measuring apparatus allows a transmitter to transmit an acoustic wave for measurement of the atmospheric pressure. Air propagates the acoustic wave. A receiver receives the acoustic wave. Since the intensity of the acoustic wave changes to follow the variation of the atmospheric pressure, the atmospheric pressure can be measured based on the intensity of the acoustic wave received at the receiver.
