Abstract: An ultrasound diagnostic device 101 is equipped with a probe distance determiner 7 and a screen creator 8. The probe distance determiner 7 analyses a positional relationship between a probe and an area subject to measurement appearing in an ultrasound image, and determines whether or not the analysed positional relationship is appropriate. The screen creator 8 notifies a user of determination results. An appropriate positional relationship is one in which a pixel region having luminance characteristics of a gelatinous medium is present between an element array of an ultrasound probe 102 and the area subject to measurement appearing in the ultrasound image, and in which the distance between the prove and the area subject to measurement exceeds a predetermined threshold across the entire length of the element array.

Abstract: An ultrasound diagnostic device including a component specifier. Assume a first direction is a depth direction substantially perpendicular to a surface of a subject, a second direction is a direction orthogonal to the first direction, a first pixel is a pixel at a pixel location N in the second direction, a second pixel is a pixel at a pixel location N+1 in the second direction, and N is a positive integer. The component specifier detects one or more feature lines from the ultrasound image by repeatedly, while incrementing N, linking the first pixel with the second pixel when luminance of the second pixel is high and the second pixel is in close proximity to the first pixel, and specifies which of the one or more feature lines indicates a boundary between components, based on an order in the first direction of the one or more feature lines.
