  • Patent number: 10159465
    Abstract: An ultrasound imaging system comprising a multi-use electronic display device and an ultrasound imaging device. The multi-use electronic display device is capable of communicating with one or more ultrasound imaging devices and selecting which to connect with based on at least one of previously store information, user input, and information gathered from the ultrasound imaging devices. The multi-use electronic display device may communicate with the ultrasound imaging devices while they are in a low power standby state. This approach reduces the complexity of the pairing process and provides a means for quickly and easily selecting between multiple ultrasound imaging devices.

  • Patent number: 10149620
    Abstract: Novel methods and systems to map the structure of blood vessels and monitor the flow of blood through these vascular networks using thermal imaging techniques. To obtain high contrast thermal images of the vascular structure in tissue, there must be a temperature difference between the blood/blood vessels and surrounding tissue. If the blood and blood vessels are warmer than the surrounding tissue, the vessels will appear brighter in thermal infrared images. A temperature contrast between blood vessels and the surrounding tissue can be achieved through selective heating of the blood. Hemoglobin has major absorption peaks near 420 and 530 nm, while absorption due to water (the dominant component of soft tissue) is significantly lower at these wavelengths. Irradiation of blood and tissue at these wavelengths produces selective heating of the blood compared to the surrounding soft tissue.

  • Patent number: 10130333
    Abstract: A combination of an ultrasonic scanner and an omnidirectional receive transducer for producing a two-dimensional image from received echoes is described. Two-dimensional images with different noise components can be constructed from the echoes received by additional transducers. These can be combined to produce images with better signal to noise ratios and lateral resolution. Also disclosed is a method based on information content to compensate for the different delays for different paths through intervening tissue is described. The disclosed techniques have broad application in medical imaging but are ideally suited to multi-aperture cardiac imaging using two or more intercostal spaces. Since lateral resolution is determined primarily by the aperture defined by the end elements, it is not necessary to fill the entire aperture with equally spaced elements. Multiple slices using these methods can be combined to form three-dimensional images.

  • Patent number: 10123816
    Abstract: In an arthroendoscopical surgical method, a resection target area, and a freshening treatment area which becomes repair surfaces with bleeding, are identified, and a resection line and a freshening line are drawn on a tear site in a meniscus, which is emphasized by fluorescence with use of a fluorescent medicine under excitation light. Using an ultrasonic treatment tool and an arthroscope, the resection target area is resected by a probe which generates ultrasonic vibrations, based on the resection line and freshening line under visible-light illumination. Thus, an inclined resection surface is formed, and planar repair surfaces with bleeding are joined and repaired.

  • Patent number: 10123704
    Abstract: A hybrid system is developed using thermal and electrical impedance imaging methods together. The innovation of the approach relies on the frequency dependence of the tissue's electrical impedance which facilitates the acquisition of multiple thermal images with currents at different frequencies injected to the region of the body under inspection. Proposed method without current application (in passive mode of operation) provides images which are obtained by standard thermal imagers. On the other hand, the application of the electrical current (in active mode of operation) increases the temperature contrast on the body surface depending on the electrical property of tissue. Therefore, the technique while increasing the thermal contrast provides frequency dependent conductivity distribution data which can be used as a basis for the detection of the breast carcinoma. The sensitivity of the technique is increased by an infrared camera with dual band (MWIR/LWIR) imaging capability.
