摘要： An ultrasonic diagnostic apparatus uses the pixel value of each of the pixels found in a predetermined range relative to a reference position of image data as input matrix and computes an output value corresponding to the input at its image processing section. Thereafter, the sorting filter of the image processing section sorts the elements of each row of the input matrix on a column by column basis. Then, it extracts a partial matrix having the row including the reference position and surrounding rows from the matrix obtained as a result of the sorting and having a number of rows smaller than number of rows of the input matrix and a number of columns same as the number of columns of the input matrix. Furthermore, it computationally determines the median of the elements of the partial matrix and outputs the median as the output value.

摘要： A measurement data processing device measures a size of a diagnostic region from a tomographic image as two-dimensional information. An ROI width determining device determines a size of a region of interest based on the size (lateral width and longitudinal width) of the diagnostic region. An oscillation angle determining device determines a range of an angle for oscillating ultrasonic transducers based on the size. An oscillation rate determining device determines a rate for oscillating the ultrasonic transducers based on information indicating the oscillation angle and image quality. In order to acquire a three-dimensional image of the diagnostic region, the probe oscillation control device controls the oscillation of the ultrasonic transducers based on the information. A three-dimensional image processing device extracts a three-dimensional image of in the determined region of interest from the acquired three-dimensional image. A display device displays the extracted three-dimensional image. Then, the three-dimensional image based on the shape of the diagnostic region is acquired.

摘要： An ultrasound imaging diagnosis apparatus and a method for supporting safe and exact puncturing operation into a target region in a living body of a patient are provided. In the ultrasound imaging diagnosis apparatus, a regions setting unit sets a target tumor region for puncturing and blood vessel regions and organ region that are located near the tumor region based on the volume data acquired by 3-D scans on the object. To avoid insertions into the blood vessel regions and organ region, a puncturing needle position detecting unit detects the tip position and the inserting direction of the puncturing needle at just before and during insertion into the object. An expected inserting position calculating unit calculates an expected inserting position and an insertion error region to the tumor region based on the tip position data, inserting direction data and characteristic data of the puncturing needle. A puncturing navigation data generating unit generates a puncturing navigation data by composing the tumor region data, the organ region and blood vessel regions data, and the data relating to the expected inserting position and the insertion error region.

Then, at least velocity ranges of the flow velocity information before and after the administration of the drug to the specimen are adjusted, and during an ultrasonic scan of the specimen, data on a plurality of acquired images having different velocity ranges are adjusted to the same velocity range. A system control unit displays the data on the plurality of images adjusted to the same velocity range on the display unit.
