Title: Ultrasonic wave diagnosis device
Inventor: JIBIKI TAKAO
IPC: A61B8/00
Filed: 1995-02-20
Abstract: PURPOSE: To prevent a flow value from being underestimated lower than its true value when a part of flow components is removed by a MTI filter. CONSTITUTION: Ultrasonic waves are transmitted to a testee' body by an ultrasonic wave probe 1, ultrasonic wave echo signals from the testee' body are received, the low frequency components of the ultrasonic wave echo signals are removed by MTI filters 9 and 10 based on filter characteristics selected in advance, and a flow dispersion value σ is thereby obtained by a CFM operation section 12 based on the ultrasonic wave echo signals from which the low frequency components are removed.  Besides, the ratio α of a reference band width to the band width of selected filter characteristics is obtained, a connection factor γ is computed by a correction factor computing section 18 by letting the band width ratio α be multiplied by an adjusting factor β, and a correction dispersion value σ" is thereby computed by a correction multiplying section 20 by letting the aforesaid flow dispersion value σ' be multiplied by the correction factor γ. By this constitution, the flow dispersion value can be prevented from being underestimated to a value parted from its true value because of the characteristics of the MTI filter, so that the reliability of diagnosis can thereby be enhanced.

Title: Method and device for displaying image while using scan type display mechanism
Inventor: JOSEPH SUE
IPC: H04N1/405
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To remove a banding phenomenon caused by nonuniformity in the scanning line intervals of display part when displaying an image area having a uniform tone, to which half-toning processing is performed by a dither method, on a raster scan type display device. SOLUTION: In the case of half-toning processing using a centralized dot- shaped dither matrix, the dither matrix is repeatedly copied and 'tiled' on a display screen. When 'tilting' the dither matrix on the display screen, dither matrix columns continuously arranged on the dither matrix in the direction crossing a scanning direction are mutually offset just for a prescribed distance in the direction crossing the scanning direction. The distance of offset is a distance having a half terminal component in comparison with the intervals of rows of dot cluster 64 generated by applying that centralized dot-shaped dither matrix, namely, is not an integral multiple of the interval of rows of the dot cluster 64 but a distance like 1/2, 1/3, 1/5, 1/8 and 9/8 of the row interval of the dot cluster 64.  Thus, the banding phenomenon caused by inequal scanning line intervals is not visually conspicuous.

Abstract: PURPOSE:To process a signal having a band width wider than the channel frequency interval by providing a signal interpolation circuit, a frequency shift circuit and a post-stage filter. CONSTITUTION:The output of a multiple sampling type transmultiplexer (MS- TMUX) 21 is supplied to a switch matrix 22, a signal having a wider band width than the channel frequency interval (DELTAf) is fed to interpolation circuits 23-1-23-5 and other channels are connected to interpolation circuits 23-6-23-K. For example, in reproducing a signal having a band width being twice the frequency interval DELTAf, only the (k+1)-th channel is frequency-shifted by +DELTAomega/2 and the k-th channel is frequency-shifted by -DELTAomega/2 by using the number of shifts of frequency circuits 24-1, 24-2 and the spectrums are added. The output spectrum of the adder 25-1 is outputted as it is in case of solid lines in figure and since the frequency characteristic in the vicinity of OHz is lifted in case of broken lines, then the output is supplied to a post-stage filter 26-1. Thus, the circuit having a completely flat frequency characteristic is realized for 2DELTAf.
