Detecting Nuclear, Electromagnetic, Or Ultrasonic Radiation Patents (Class 600/407)
  • Patent number: 9810650
    Abstract: Photothermal imaging systems and methods are disclosed that employ truncated-correlation photothermal coherence tomography (TC-PCT). According to the example methods disclosed herein, photothermal radiation is detected with an infrared camera while exciting a sample with the chirped delivery of incident laser pulses (where the pulses have a fixed width), and time-dependent photothermal signal data is obtained from the infrared camera and processed using a time-evolving filtering method employing cross-correlation truncation. The cross-correlation truncation method results in pulse-compression-linewidth-limited depth-resolved images with axial and lateral resolution well beyond the well-known thermal-diffusion-length-limited, depth-integrated nature of conventional thermographic and thermophotonic modalities.

  • Patent number: 9789267
    Abstract: A portable vein viewer apparatus may be battery powered and hand-held to reveal patient vasculature information to aid in venipuncture processes. The apparatus comprises a first laser diode emitting infrared light, and a second laser diode emitting only visible wavelengths, wherein vasculature absorbs a portion of the infrared light causing reflection of a contrasted infrared image. A pair of silicon PIN photodiodes, responsive to the contrasted infrared image, causes transmission of a corresponding signal. The signal is processed through circuitry to amplify, sum, and filter the outputted signals, and with the use of an image processing algorithm, the contrasted image is projected onto the patient's skin surface using the second laser diode. Revealed information may comprise vein location, depth, diameter, and degree of certainty of vein locations. Projection of vein images may be a positive or a negative image. Venipuncture needles may be coated to provide visibility in projected images.

    Abstract: Techniques for modeling therapy fields for therapy delivered by medical devices are described. Each therapy field model is based on a set of therapy parameters and represents where therapy will propagate from the therapy system delivering therapy according to the set of therapy parameters. Therapy field models may be useful in guiding the modification of therapy parameters. As one example, a processor compares an algorithmic model of a therapy field to a reference therapy field and adjusts at least one therapy parameter based on the comparison. As another example, a processor adjusts at least one therapy parameter to increase an operating efficiency of the therapy system while substantially maintaining the modeled therapy field.

    Abstract: A distance calculation unit acquires a first position information indicating a position of a part of a body of each user indicated in an image captured by an imaging device. A user information analysis unit detects an operation region where a user can operate by using a part of a body, based on the first position information, and that identifies as an operator candidate a user having the part of the body indicated by the first position information in case that the detection of the operation region was possible. The user information analysis unit, of operator candidates, identifies as an operator a user including a part of the body in the operation region, and identifies as a user who cannot perform operation a user other than a user identified as the operator of the operator candidates.

  • Patent number: 9709513
    Abstract: An apparatus and method of measuring an object (having at least two edges) projects a plurality of x-ray images of the object. At least two of the plurality of x-ray images are projected from different directions relative to the object. The apparatus and method also locate the at least two edges in the x-ray images, and ray trace a plurality of lines. Each ray traced line is tangent to at least one point on at least one of the located edges. Next, the apparatus and method reconstruct at least a partial wireframe model of the object from the tangent points of the ray traced lines. The wireframe model includes the at least two edges. Finally, the apparatus and method measure between the at least two edges of the at least partial wireframe model.

  • Patent number: 9700244
    Abstract: A degradation data generator is used with a scaffold for delivery within a patient. The degradation data generator includes a driving circuit electrically coupled to drive an impedance of the scaffold. A detection circuit generates degradation data based on the impedance of the scaffold or other properties such as RF or lightwave transmission, conductance or absorption. The degradation data indicates an amount of biodegradation of the scaffold. A wireless transmitter is coupled to transmit the degradation data to a wireless degradation data receiver, while the scaffold is within the patient.

  • Patent number: 9684972
    Abstract: An imaging apparatus for imaging an object includes a geometric relation determination unit configured to determine a geometric relation between first and second images of the object. A marker determination unit configured to determine corresponding marker locations in the first and second images and marker appearances based on the geometric relation such that the marker appearances of a first marker to be located at a first location in the first image and of a second marker to be located at a second corresponding location in the second image are indicative of the geometric relation. The images with the markers at the respective corresponding locations are shown on a display unit. Since the marker appearances are indicative of the geometric relation between the images, a comparative reviewing of the images can be facilitated, in particular, if they correspond to different viewing geometries.

  • Patent number: 9682255
    Abstract: A medical apparatus (600, 700, 800) including a high intensity focused ultrasound system (602), a signaling device (628) for generating a discomfort signal during the sonication of the sonication volume, and a processor (634) for executing instructions. Execution of the instructions causes the processor to receive (102) a set of sonication points (658, 904). At least one of the set of sonication points is identified as a test location (908, 912). The instructions further cause the processor to perform for each sonication point: determine (106) if it is a test location; perform (108) a test sonication (204, 304, 404, 504) if it is a test location; repeatedly test (110) for the discomfort signal during the test sonication; sonicate (114) the sonication point if it is not a test location or if the discomfort signal was not detected; and abort (112) the sonication if the discomfort signal was detected.

  • Patent number: 9672631
    Abstract: This invention relates generally to medical imaging and, in particular, to a method and system for reconstructing a model path through a branched tubular organ. Novel methodologies and systems segment and define accurate endoluminal surfaces in airway trees, including small peripheral bronchi. An automatic algorithm is described that searches the entire lung volume for airway branches and poses airway-tree segmentation as a global graph-theoretic optimization problem. A suite of interactive segmentation tools for cleaning and extending critical areas of the automatically segmented result is disclosed. A model path is reconstructed through the airway tree.
