Abstract

The present invention enables ultrasonic propagation time values after correction of refraction to be calculated in parallel for each receive channel, by using a recurrence relation in the depth direction. Moreover, accumulation of errors can be avoided by using an accurate propagation time value obtained in advance at a reference depth to correct the propagation time value each time the reference depth is reached. For this error correction, the recurrence relation to calculate the propagation time value can be an approximate expression. For example, the propagation time value can be calculated using the inclination of reference propagation time values between reference depths. In an actual circuit, received signals are sequentially stored in a memory, and a receive beam is formed by calculating an address position corresponding to the propagation time value of the ultrasonic wave, and adding the received signals stored in the calculated addresses.

Description

Technical field [0001] The present invention relates to an ultrasonic imaging device for receiving ultrasonic waves reflected or generated in a subject and imaging the received ultrasonic waves, and more specifically, to an ultrasonic imaging device for forming a receiving beam from a plurality of receiving beams. A digital ultrasonic imaging device that performs delay correction of the signal obtained by the element according to the ultrasonic wave propagation time. Background technique [0002] Since ultrasound does not produce exposure and is basically non-invasive, ultrasound image diagnosis is widely used. Especially in recent years, due to the advancement of digitization of ultrasonic imaging devices, it is possible to easily control the delay time generated for forming the ultrasonic beam with high accuracy. According to this, it is possible to obtain high-quality biological tomographic images by using a compact device for diagnosis of each area. In addition to ultrasoni...
