Provided is an ultrasound diagnostic device whereby it is possible to create a three-dimensional image which presents a shadow effect caused by light leakage, absorption, etc. This ultrasound diagnostic device which displays a three-dimensional image of a subject on the basis of brightness volume data comprises: a light source information setting unit which sets light source data which represents a light source characteristic which is set in a three-dimensional space; an optical characteristic setting unit which sets a weighting coefficient which represents an optical characteristic of the brightness volume data with respect to the light source; an illumination computation unit which, on the basis of the optical data and the weighting coefficient, computes illumination of a location corresponding to the brightness volume data coordinates, and creates illumination volume data on the basis of the computed illumination; and a projection processing unit which creates the three-dimensional image from the brightness volume data and the illumination volume data. |
