| 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.
