摘要： The microstructure of bone is analyzed with ultrasonic waves. Cancellous bone is modeled in advance into a plurality of two-dimensionally arranged circular cylinders in view of ultrasonic wave scattering and the theoretical formulae of the model are derived. Then an organism is subjected to ultrasonic waves and reflected waves from the cancellous bone are received. The frequency characteristics of received signals generated by the reception of the ultrasonic waves is calculated and the unknown values of the parameters contained in the theoretical formulae are estimated based on the frequency characteristics. The interval between trabeculae and the thickness of each trabecula are estimated as the values of the parameters.

摘要： A displacement estimation method is described that limits the exhaustive search for all points in a region of interest of a biological tissue by delivering the axial and lateral displacement maps in two phases. During the first phase, the method executes a limited search to determine axial and lateral displacement estimates for a plurality of locations on at least one axial reference line positioned in the ROI. Non-zero estimates form transition points along the axial reference line where one non-zero transition point value differs from another. During the second phase, the method laterally tracks each, transition point throughout the ROI using block-matching algorithms or correlation methods. The displacement estimations identify a trajectory of the transition point through the ROI and form a displacement map. The plurality of transition point displacement maps are assembled as a complete displacement map. The resultant displacement map is used to form a tissue strain display.

摘要： A finite impulse response filter is implemented as a sum of individual component, running-sum Filters. The sum of all of the component niters required for a desired filter response is calculated in an accumulator and only the update terms are calculated for each componen filter. A desired impulse response is decomposed into a sum of rectangular impulse responses of equal height, each of which is implemented as a running sum requiring a subtraction and an addition. Using circuits running at a multiple of the sampling clock, multiple running sums may be implemented on the same hardware. A whole filter of arbitrary impulse response shapes and lengths ma be implemented using memory and two arithmetic units. Two or more such filters may be cascaded to obtain a better approximation of the desired frequency characteristic. The invention saves chip resources and manufacturing costs.
