1. An ultrasound medical apparatus comprising: a hardware processor which generates a Doppler image from Doppler data regarding a target body received from an ultrasound probe coupled to the ultrasound medical apparatus, acquires a guideline regarding at least one of the Doppler data and the Doppler image, and generates a plurality of first markers each indicating a moving direction of the target body at a different respective location of the target body, wherein the hardware processor determines the moving direction based on the guideline and the Doppler data; and a display coupled to the hardware processor, which displays the plurality of first markers each indicating the moving direction of the target body at the respective location based on the guideline and the Doppler data, wherein the hardware processor determines a percentage of the generated first markers indicating a direction opposite to a direction towards a first end of the guideline and, if the determined percentage is below or equal to a predetermined percentage, the hardware processor generates a second marker indicating an inconsistent direction at a location of a first marker indicating the opposite direction and the display displays the second marker, and wherein the hardware processor determines whether the moving direction of the target body is determined based on the guideline and the Doppler data and, upon determining that the moving direction of the target body cannot be determined based on the guideline and the Doppler data, the hardware processor generates a third marker indicating that the moving direction of the target body is not determined, relocates the guideline, and determines the moving direction of the target body based on the relocated guideline and the Doppler data, and the display displays the third marker and relocated guide line, and wherein the hardware processor generates the Doppler image to include a blood flow Doppler image showing flow of blood and a tissue Doppler image showing movement of a tissue, specifies a plurality of regions including at least one region having flow of blood in the Doppler image and including at least another region having movement of the tissue in the Doppler image based on the automatic detection algorithm, acquires a plurality of guidelines for the plurality of regions, and determines the moving direction of the flow of blood and of the movement of the tissue for the plurality of regions based on the plurality of guidelines and the Doppler data.
