Title:
ULTRASONIC DIAGNOSTIC DEVICE
Document Type and Number:
Japanese Patent JP3231529
Kind Code:
B2
Abstract:
PURPOSE: To provide a flexible ultrasonic diagnostic device for performing high-speed three-dimensional ultrasonic scanning and reducing the burden of a patient with simple configuration.
CONSTITUTION: This device is provided with a rotating means for rotating an ultrasonic vibrator transducer, axial direction moving means such as a stepping motor 30 for axially moving the vibrator transducer, display means for displaying the ultrasonic tomographic image of a reagent synchronously with the rotating means, image fetching means for fetching the ultrasonic tomographic image synchronously with the axial movement of this vibrator transducer, and means for varying the fetching interval of the ultrasonic image. For example, the fetching interval is widened by accelerating the axial moving speed by turning the motor 30 at high speed corresponding to the switching of high-speed and low-speed clocks from a clock supplying part 33, and the fetching interval is narrowed by turning the motor at low speed. Normally, the fetching interval to be provided is widely set, the number of ultrasonic tomographic images is decreased, time for fetching is shortened, and the burden of the patient is reduced. When precision is required, detailed information is provided by narrowing the fetching interval corresponding to switching. Operability is improved as well.
