摘要： PROBLEM TO BE SOLVED: To realize an efficient signal processing by using a plurality of processors in an ultrasonic diagnostic system. SOLUTION: A beam processing part 46 includes a pre-processing unit 48, a processor A50, a processor B52, and a processor C54. Namely, a processor line composed of the three processors 50, 52, 54 is configured. Each of the processors includes a set of the same subprograms (routines). In accordance with an operating mode and processor disposing ranking, a routine corresponding to the operating mode is carried out for each processor, so that inputted received data are processed. For example, a B-mode processing program is divided into three routines and these routines are carried out in each of the processors 50, 52, 54, so that a processing burden is distributed, Further, the set of the same routines can be stored in each of the processors 50, 52, 54 to flexibly deal with a design change even if a design is changed.

摘要： PROBLEM TO BE SOLVED: To solve the problem that the load for logarithmic transformation is increased when the number of bits of echo data is large in ultrasonic diagnostic equipment. SOLUTION: The echo data stored in a register 20 is divided into two partial bit strings. A control circuit 32 discriminates whether a value X1 expressed by a higher-order partial bit string D1 is 0 or not. When it is 0, logarithmic conversion is performed to D1 by a logarithmic converter 24. An adder 26 adds an offset bit string Δ1 according to the position of D1 in the bit string of the echo data to this logarithm Log X1. The control circuit 32 controls a switch 28 and outputs this addition result to a multiplier 30. In the case of X1≠0, logarithmic conversion is performed to a lower-order partial bit string D2 having a value X2 and the resultant Log X2 is outputted to the multiplier 30. Data multiplied by a constant α by the multiplier 30 is outputted from a logarithmic transformation part as data obtained by performing logarithmic transformation approximately to the echo data.

摘要： PROBLEM TO BE SOLVED: To provide a structure improved for realizing resampling processing.
SOLUTION: A window 42 of filter coefficients comprising N number of coefficients clips N number of input data from an input data row 40, and respectively multiplies clipped N number of input data with coefficients, and output data is created by adding the input data after the multiplication. The window 42 of filter coefficients is shifted in a step 46 corresponding to a data thinning-out ratio. First, a window with input data 0 of the input data row 40 as the head is set. Then, a window with input data 2 as the head is set by skipping input data 1. The output data is acquired one after another while every other input data is skipped. As a result, thinning-out processing is performed at the data thinning-out ratio of 0.5. A coefficient for an FIR filter is set to prevent loopback distortion of high-frequency components after the thinning processing.

摘要： PROBLEM TO BE SOLVED: To solve the problem of blooming that a blood flow runs off the edge of a structure such as blood vessels by appearances when a two-dimensional blood flow image is displayed on a two-dimensional tomographic image. SOLUTION: A first threshold value processing device 34 directly outputs information on the inputted velocity when information on power is greater than a threshold value α1. A second threshold value processing device 36 directly outputs information on the inputted velocity after the first threshold value processing when the power after a logarithmic conversion is greater than a threshold value α2. In the second threshold value processing, the information on the inputted velocity is made not to be outputted when the power after the logarithmic conversion is smaller than the threshold value α2. Consequently, a low level component is extended by the logarithmic conversion, and an ultrasonic diagnostic apparatus has an advantage to perform threshold value processing precisely by facilitating setting of the threshold value.

摘要： PROBLEM TO BE SOLVED: To simplify the gain adjustment of a display, in the display (velocity display by color) indicating a velocity by color information of an ultrasonic diagnostic apparatus. SOLUTION: This gain adjusting method includes counting the number of times when a signal level of a color velocity display exceeds a predetermined threshold and calculating a frequency exceeding the threshold. The gain is adjusted based on the frequency. At first, a rough adjustment counting section 36 calculates the frequency in a rough adjustment time, and when the frequency is out of a predetermined range, a rough adjustment section 38 adjusts the gain. When the frequency is within the predetermined range, a fine adjustment counting section 40 calculates a frequency when the signal level in a fine adjustment time exceeds the threshold and a fine adjustment section 42 adjusts the gain based on the result. The rough adjustment time is shorter than the fine adjustment time, so that this method can acquire a suitable gain in an early stage. COPYRIGHT: (C)2009,JPO&INPIT
