Ultrasonic imaging method and ultrasonic imaging apparatus |
摘要 |
An ultrasonic imaging method capable of increasing density of sampling points in accordance with depths within an object. In this method, a predetermined area contained in the object is divided into at least a first area located most shallowly and a second area located deeper. The method includes the steps of: (a) transmitting and receiving ultrasonic waves focused in one focus direction within the first area to take samples of an ultrasonic image at a plurality of points in the focus direction, and changing the focus direction to scan the first area; (b) sequentially transmitting ultrasonic waves focused in respective focus directions within the second area in a predetermined time period, thereafter receiving ultrasonic waves reflected from the respective focus directions to take samples of the ultrasonic image at a plurality of points in the respective focus directions.
