Patent ID: 8285012

Claim:
An image display apparatus comprising: a device which reads in an image data set of a subject acquired by a medical imaging apparatus from a data recording device which stores the image data set; an input device which inputs a desired object organ to the read-in image data set; an object organ extracting device which extracts the inputted object organ; a reference position setting device which sets a reference position of the extracted object organ; a calculating device which calculates at least one of (a) a radial direction value representing density values of pixels arrayed in a radial direction of the object organ, the radial direction value being at least one of maximum value, minimum value and average value of the density values of pixels arrayed in the radial direction of the object organ, and (b) an angular direction value representing density values of pixels arrayed in angular direction of the object organ; and an image display device which displays at least one of (i) the radial direction value on a plane including a positional axis indicating positions in the center line direction of the object organ and an angular direction axis indicating angles around the center line of the object organ from the set reference position and (ii) the angular direction value on a plane including the positional axis and a radial direction axis indicating distances from the center line of the object organ.
