1. An imaging method of an ultrasonic imaging apparatus, wherein the ultrasonic imaging apparatus comprises an ultrasonic signal emission source and a receiving array that comprises a plurality of ultrasonic signal receiving circuits, both of which define a detection region; the detection region comprises a farthest interface, which is an edge interface of the detection region distal to the receiving array; the ultrasonic imaging apparatus is configured to detect an object to be detected in the detection region; and the imaging method comprises:
turning on the ultrasonic signal emission source to perform a first emission of ultrasonic waves toward the detection region and causing the ultrasonic waves to propagate through the detection region, a depth-wise direction of which is along a propagation direction of the ultrasonic waves, and thereafter, turning off the ultrasonic signal emission source; and
turning on the receiving array at a first time point after a first predetermined time period having elapsed since the ultrasonic signal emission source was turned on, so as to simultaneously receive a plurality of reflected echoes returning from the detection region by the plurality of ultrasonic signal receiving circuits comprised in the receiving array; thereafter, causing the receiving array not to receive any reflected echoes, storing the plurality of reflected echoes by the plurality of ultrasonic signal receiving circuits, acquiring a plurality of reflected echo signals as a plurality of reflected echo signals relating to a first slice in the first emission, and reading the plurality of reflected echo signals relating to the first slice successively from the plurality of ultrasonic signal receiving circuits during a reading time period.
