Claim One:
1. A method of producing an ultrasound image, comprising: with an ultrasound probe, performing transmission and reception of an ultrasonic beam toward a blood vessel in a subject based on an actuation signal and outputting a reception signal of the ultrasonic beam; with a transmission/reception circuit, producing the actuation signal and producing a sound ray signal obtained by processing the reception signal; with a candidate vascular wall boundary point determining processor, determining candidate vascular wall boundary points based on the sound ray signal; with a first evaluation value calculating processor, calculating a first evaluation value representing accuracy of each of the determined candidate vascular wall boundary points as a vascular wall boundary point; with a second evaluation value calculating processor, by means of a sound ray signal in a predetermined depth range including the determined candidate vascular wall boundary points and a sound ray signal adjacent to the sound ray signal, calculating a second evaluation value representing similarity between the sound ray signal and the adjacent sound ray signal; with a third evaluation value calculating processor, calculating a third evaluation value for determining the vascular wall boundary point from among the candidate vascular wall boundary points based on the first evaluation value and the second evaluation value; and with a boundary determining processor, determining the vascular wall boundary point based on the third evaluation value and determining a vascular wall boundary based on the determined vascular wall boundary point.
