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.

Disclosed are methods of graphically displaying digital data containing a predetermined number of digital values, on a display area containing a lower, predetermined number of graphical display elements. One disclosed method includes the steps of attributing to each display element a portion of the digital values, the total number of digital values in all portions being equal the total number of digital values so that variability among the portions is periodic and calculating a representative digital value for each portion and displaying the representative value on a discrete display element in the display. Also disclosed is a method of determining for each graphical display element in an apparatus with a lesser number of graphical display elements a corresponding number of digital values to represent, the digital values being selected from a stream containing a greater number of digital values. The method includes the steps of dividing the greater number by the lesser number to ascertain a quotient and determining for each graphical display element a corresponding number of digital values to represent, based on the quotient. According to this method, the apparatus uses a known method of representing a plurality of digital values using a single graphical display element.

A method and system for ultrasonic imaging of bone tissue. A wide band scanning crystal transmits an ultrasonic signal of high frequency and multiple full waves into the bone tissue, and a second wide band scanning crystal receives the transmitted signal. The transmission frequency is progressively decreased until the number of full waves in the received signal equals that of the transmitted signal. At that frequency, the upper frequency limit, the number of full waves in the transmitted signal is gradually increased until the received signal contains at least two consecutive full waves of equal amplitude. The resultant transmission signal is then used to measure signal attenuation and velocity in bone tissue, in terms of standard bone imaging techniques. A lower frequency limit, below which the received signal undergoes distortion, is defined, and ultrasonic velocity depicted as a function of transmission frequency. Received ultrasonic wave frequency spectra, and the difference between the upper and lower frequency limits, are all used to image the bone tissue. Probe orientation is enhanced by a mechanism whereby a third wide band screening crystal receives the transmitted signal concomitantly with the second screening crystal. The signals received by the two wide band scanning crystals are correlated with each other to give a numerical indicator of the adequacy of probe orientation.
