摘要： An input device for specifying a first measuring point near an orifice, for example, at the valve port position of the heart on a color Doppler image and a second measuring point on the centerline of an issuing fluid is connected to a blood flow imaging device which is a color Doppler tomograph constituted by combining a sector electronic scanning type ultrasonic diagnostic device and an Doppler system to derive blood flow information and tomographic image (B mode image) information by using a single ultrasonic probe. The blood flow imaging device derives Doppler shift frequencies at the first and second measuring points and supplies the same to a flow-rate calculating circuit. The flow-rate calculating circuit derives flow velocities of the blood at the first and second measuring points and a distance between the first and second measuring points and calculates the flow-rate based on the derived flow velocities and distance. The blood flow information and tomographic image obtained by the blood flow imaging device and the calculating result of the flow-rate calculating circuit are supplied to a display control circuit via a CPU bus and displayed on an display unit under the control of the display control circuit.

摘要： An ultrasound diagnosing system includes an ultrasound transmission/reception section, a cross-sectional imaging section, a phase detection section, a filter section, a calculation section, a correction section and a display section. The cross-sectional imaging section causes the ultrasound transmission/reception section to perform ultrasound scanning for sending and receiving ultrasound beams a plurality of times at an identical beam position, and detects cross-sectional information on a living subject from the echo signals. The phase detection section performs quadrature detection of the echo signals. The filter section eliminates low-frequency clutter components from two sets of detected echo components. The calculating section calculates an average blood flow speed by using the outputs of the filter section by autocorrelation. The correction section substracts the average values of the echo components from the two sets of the echo components before the calculation results are obtained, to eliminate the DC components included in the echo components. The display section superposes two-dimensional information on the average blood flow speed from the calculating section on the cross-sectional image and displays a superposed image.

摘要： The sequence for a case of scanning by an ultrasound prove having a plurality of transducers, for example, m numbers, is as follows: first scan line.fwdarw.(m-l)th scan line.fwdarw.mth scan line.fwdarw.first scan line.fwdarw.second scan line.fwdarw.mth scan line.fwdarw.first scan line.fwdarw.second scan line.fwdarw.third scan line.fwdarw.first scan line.fwdarw.. . . The ultrasound probe transmits ultrasound beams to a subject and receives echo signals reflected from the subject in accordance with the above sequence. Doppler signals obtained from the echo signals are stored in a memory. When the predetermined number of Doppler signals in each line are stored in the memory, the Doppler signals in each line are read out from the memory. By such scanning sequence, a repeat frequency, i.e., a sampling frequency of Doppler signals of the ultrasound beams transmitted in the same direction, is a shorter. As a result, a low limit of measurable flow velocity is a lower, and a timing for reading out (outputting) the Doppler signals from the memory can be a constant.
