  • Patent number: 11426105
    Abstract: Optical coherence tomography (herein “OCT”) based analyte monitoring systems are disclosed. In one aspect, techniques are disclosed that can identify fluid flow in vivo (e.g., blood flow), which can act as a metric for gauging the extent of blood perfusion in tissue. For instance, if OCT is to be used to estimate the level of an analyte (e.g., glucose) in tissue, a measure of the extent of blood flow can potentially indicate the presence of an analyte correlating region, which would be suitable for analyte level estimation with OCT. Another aspect is related to systems and methods for scanning multiple regions. An optical beam is moved across the surface of the tissue in two distinct manners. The first can be a coarse scan, moving the beam to provide distinct scanning positions on the skin. The second can be a fine scan where the beam is applied for more detailed analysis.

  • Patent number: 11065470
    Abstract: A catheter treatment apparatus comprises an elongate tubular member and an expandable support. The expandable support comprises a radioactive substance to treat cancerous tissue and is configured to expand from a narrow profile for insertion to a wide profile to engage and treat tissue remaining after resection. The expandable support can be sized to fit within a volume of removed tissue to place the radioactive substance in proximity to the capsule and remaining tissue, to spare the capsule and proximate nerves and vessels to treat tissue in proximity to the capsule. The elongate tubular member may comprise a channel such as a lumen to pass a bodily fluid such as urine when the expandable support engages the tissue to treat the patient for a plurality of days. The treatment apparatus can be used to resect and diagnose tissue concurrently. Based on the diagnosis, targeted segmental treatment may be given.

  • Patent number: 10883940
    Abstract: A fluctuation-based fluorescence microscopy method, comprising influencing a point-spread function of the imaging of a sample emitting fluorescence radiation using an optical device in dependence on a parameter such that a point emitter is imaged into a representation with two image lobes. The relative positions of the lobes depend on the position of the point emitter relative to the focal plane. Synthetic pixels, smaller than detector pixels, are generated; for each synthetic pixel, pairs of pixel groups are defined among pixels of the detector based on the influencing of the point spread function. Each pair is assigned to an individual value of the parameter. In each frame and for each synthetic pixel, a signal correlation is ascertained and allocated as image brightness to the synthetic pixel for the parameter specification. Subframes for each frame are produced from the synthetic pixels, and a high-resolution sample image is produced from the subframes.
