摘要： An ultrasonic diagnostic system includes a probe composed of a group of transducers for transmitting and receiving an ultrasonic wave, a main system connected with the probe by a cable, a memory card, and a battery pack for supplying power. The ultrasonic diagnostic system further includes a data processing unit and a monitor which are provided separately from the above components. The probe and main system are prepared for each ultrasonic scanning mode. The data processing unit subjects the received signal data recorded in the memory card to sophisticated data processing which cannot be carried out by the main system thereby to display the processing result. An examiner can carry the probe, main system, memory card and the battery pack for supplying power instead of a stethoscope to acquires diagnosis data and can process a suspicious image in diagnosis at bedside or house call using the data processing unit thereby to implement precise diagnosis.

摘要： A phase adjustment circuit for use in an ultrasonic apparatus which respectively time-adjusts a plurality of received signals from an ultrasonic transducer array and sets wave fronts of the reflected waves from particular positions into an in-phase state and adds the in-phase signals, thereby obtaining a received beam. The received signals are mixed with phase-controlled reference signals. The low frequency component of the mixed wave is sequentially sampled and stored in a memory which is controlled by a clock signal of a predetermined period, and thereafter, the stored sampled signals are read out. Most of the necessary time adjustment results from the difference between the writing time and the reading time. The remaining micro time adjustment is performed by phase control of the reference signals.

摘要： An ultrasonic flow mapping apparatus transmits and reflects waves from sampling points on a two-dimensional cross-section. The waves are detected while transmitting repeatedly ultrasonic pulses. The phase shifts of different reflected waves are calculated, and displayed in color to show a distribution of blood flow velocity. Artifact due to reflected waves from body organs, which remain even by using MTI filters, is detected from phase signals, which have not passed through the MTI filters, and the artifact is removed by lowering display brightness for a sampling point corresponding to a relevant detection output.
