Abstract:
1. An ultrasound diagnosis apparatus, comprising: a probe configured to perform an alternating scan along a raster in each of plural Doppler groups of ultrasound beam directions so as to acquire first and second Doppler-mode image frames; a controller coupled to the probe and configured to control the probe to treat a last group of the ultrasound beam directions for the first Doppler-mode image frame and an initial group of the ultrasound beam directions for the second Doppler-mode image frame as one Doppler group of the ultrasound beam directions; a processor coupled to the probe and configured to detect a Doppler-mode signal based on the alternating scan along a raster so as to prepare the first and second Doppler-mode image frames; and an output unit coupled to the processor and configured to output the prepared first and second Doppler-mode image frames.
