Latest Patents

Among his latest innovations is an ultrasonic diagnostic apparatus that acquires a tomogram of a subject and displays it based on a reception signal obtained by transmitting and receiving ultrasonic waves. This apparatus features maximum value memory circuitry, select circuitry, and an ultrasonic output controller. The maximum value memory circuitry stores the maximum value of an index value related to ultrasonic output for each scan region of the subject. The ultrasonic output controller ensures that the ultrasonic output does not exceed this maximum value. Another notable patent involves a transmission processing unit that transmits ultrasonic waves in Doppler mode and other modes. The reception processing unit captures the reflected ultrasonic waves as echo signals, which are then used to generate images in both modes. The control unit adjusts the transmission ratio of the ultrasonic waves based on the subject's pulsatory degree.
