  • Patent number: 9036140
    Abstract: An optical probe system having a probe with an optical guide (G) having a distal end. The optical guide (G) is mounted inside a housing (H) so that the distal end is displaceable with respect to the housing (H). A set of actuators (A), e.g. electromagnetic drive coils, can displace the distal end by application of a drive signal (Vx, Vy). A control unit (CU) generates the drive signal (Vx, Vy) so as to provide a scanning frequency which varies according to an amplitude of the drive signal (Vx, Vy). With such probe system it is possible to scan a field of view with a scanning frequency that varies with the scanning radius. Taking into account the maximum allowable drive current, it is possible to increase scanning speed compared to scanning at the mechanical resonance frequency of the optical system, since small radii can be scanned at a high scanning frequency.

    Abstract: A method for determining the hematocrit of a blood sample is provided that includes the steps of: 1) depositing the sample into an analysis chamber adapted to quiescently hold the sample for analysis, the chamber defined by the interior surfaces of first and second panels and a height extending there between, wherein both panels are transparent, and the height is such that at least some of the red blood cells within the sample contact both interior surfaces of the panels and one or more lacunae within the quiescent sample extend between the interior surfaces; 2) imaging at least a portion of the quiescent sample, which sample portion contains the red blood cells and one or more lacunae to determine an optical density of the imaged portion of the sample on a per image unit basis; 3) selecting and averaging the optical density values of the image units aligned with the red blood cells contacting the interior surfaces, and assigning an upper boundary value of 100% to the average optical density value of those im

  • Patent number: 8062222
    Abstract: The present invention relates a method for assessing in vivo hematotoxicity. The method utilizes differential staining of nucleated and non-nucleated blood cells, and also differential labeling of cells with functional versus dysfunctional mitochondrial membrane potential. Quantitative analyses can be conducted on stained whole blood specimens, and is based on blood cells' fluorescent emission and light scatter properties following exposure to an excitatory light source. The ratio of certain cell populations can be readily measured. Furthermore, it is also possible to express cell population values in terms of number per unit volume. This invention can be used to evaluate the hematotoxicity of drugs, chemicals, radiation, and other exogenous agents, or the effects that a suspected protective agent may have on induced hematotoxicity. Furthermore, the matrix of measurements provided by this invention is useful in estimating radiation dose, i.e., retrospectively.

  • Publication number: 20110196214
    Abstract: A hand-held analyzer for collecting a sample of blood from the scalp of a fetus and measuring the pH or other blood characteristic of the blood sample. The analyzer includes a probe with a proximal end and a gasket that facilitate a firm and positive placement of the probe against the scalp. The probe includes a capillary tube for collecting blood and an extensible lancet which at rest is positioned within the capillary tube. During operation, the lancet is extended to make an incision in the scalp. The lancet then retreats, and blood flows into the capillary tube. Sensors for measuring pH are in liquid communication with the capillary tube. A display on or near the hand-held analyzer shows a readout of the fetal scalp blood pH or other blood characteristic. Measuring the pH of the fetal scalp blood in utero can provide early detection of acidosis and likely hypoxia.

  • Publication number: 20110077496
    Abstract: The invention provides a method and apparatus obtaining a hematocrit from a sample of in vivo tissue. The method comprises irradiating the sample with a single incident wavelength on a sample of tissue, simultaneously measuring wavelength shifted (IE) and unshifted (EE) light emitted from the tissue, and determining a relative volume of light emitted from two phases, wherein the two phases comprise a first Rayleigh and Mie scattering and fluorescent phase associated with red blood cells, and a second, non-scattering phase associated with plasma. The hematocrit is calculated from the volume of light emitted by the first phase relative to the total volume of light emitted from the first and second phases.

  • Publication number: 20110060205
    Abstract: The invention relates to a general composite compartmental model and a compartmental analysis procedure to extract non-invasively the concentration (Cp) of the imaging agent in plasma (301), in metabolites (304, 504) and in blood elements (303) (like red cells, platelets, plasma protein etc.) from time signal curves measured within a reference tissue region (200). This is made possible by deploying an injection function (SINJ(t)) as input which models the amount of imaging agent administered to the patient as a function of time. The invention allows the presentation of the plasma input function to the medical practitioner without the need for invasively drawing blood samples.

    Abstract: Methods, apparatus and systems for characterizing changes in at least one physical property of soft tissue. A series of acoustic pulses is generated and directed into the soft tissue such that at least one of the pulses is of sufficiently high intensity to induce physical displacement of the tissue. Waves reflected off the tissue, or a flexible member that moves with the tissue, are received and measured to estimate at least one characteristic of the physical displacement induced thereby. Repetition of the generating, receiving and estimating steps provides characterization of the at least one physical property over time. Methods, apparatus and systems for characterizing at least one physical property of blood, by generating a series of acoustic pulses and directing the series of pulses into the blood such that at least one of the pulses is of sufficiently high intensity to induce physical displacement of the blood.
