A medical imaging apparatus and a method of generating a medical image that are capable of generating a Doppler image by using a Doppler effect as well as an ultrasound image are disclosed. The method of generating a medical image includes: acquiring received signals； acquiring an ultrasound image and displaying the acquired ultrasound image； acquiring a Doppler signal corresponding to a sample volume that is set on the ultrasound image, based on the received signals； generating a Doppler image based on the Doppler signal and displaying the generated Doppler image； receiving a user input for moving a location of the sample volume； and suspending, if the user input is received, the displaying of the Doppler image and updating the ultrasound image.
