  • systems for ultrasonic imaging of a jaw, methods of use thereof and coupling cushions suited for use in the mouth
    Patent number: 7285093
    Abstract: Systems and methods for ultrasonic imaging of a jaw and coupling cushions suited for use in the mouth. The system includes a specially configured ultrasonic probe, a position locator module for defining a probe location and transmitting the definition to a central processing unit (CPU) and the CPU. The CPU is capable of receiving digital data from transducers in the probe and receiving the location of the probe and producing an image of at least a portion of a jaw. The method includes providing the ultrasonic probe, defining its location and communicating the location to a CPU and transmitting an signal from a transducer and receiving at least a portion of the signal at at least one of the transducers. The CPU receives transducer data and a location of the probe and produces an image of the at least a portion of the jaw. An ultrasonic coupling cushion is further disclosed.

  • Image processing device to determine image quality and method thereof
    Publication number: 20070041657
    Abstract: An image processing device that determines the image quality includes a division unit dividing image data into a plurality of divided images, a calculation unit calculating luminance histograms of the respective divided images, and a judgment unit judging qualities of the respective divided images using the luminance histograms of the divided images and judging the quality of the image data in consideration of rates of the judged qualities. Accordingly, the quality of the image data can be determined more accurately and more precisely.
