Engineering Contradiction Analysis
1Measurement precision
If manual extraction and adjustment of flow velocity information is performed, then measurement precision can be maintained, but loss of time increases and productivity decreases
Solution Approach 1:
The system automatically extracts flow velocity information from ultrasonic signals and performs temporal changes analysis without operator intervention. The automatic extraction unit identifies peak blood flow velocities and the temporal changes display unit generates visual representations, enabling the system to serve itself in the measurement process while maintaining precision.

The patent replaces manual mechanical adjustment and visual inspection methods with automated computational processing. The automatic extraction unit uses signal processing algorithms to identify flow velocity peaks, and the temporal changes display unit uses computer-generated visualizations to show velocity changes over time, substituting operator-based mechanical adjustments with automated electronic processing.

AI summary
An ultrasonic Doppler diagnostic apparatus sends ultrasonic waves to a specimen, receives a reflection signal of the ultrasonic waves from the specimen to detect a Doppler signal, obtains blood flow information indicating a peak flow velocity of coronary blood flow, and displays the flow velocity information before and after the administration of a drug to the specimen on a display unit. 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.
