Image display apparatus and program

An image display program in a non-transitory medium embodying instructions causing a computer to execute:

• a step of reading in an image data set of a subject acquired by a medical imaging apparatus from a data recording device which stores the data set;
• an input step of inputting a desired object organ to the read-in image data set;
• an object organ extracting step of extracting the inputted object organ;
• a reference position setting step of setting a reference position of the extracted object organ;
• a calculating step of calculating 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 , 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 displaying step of displaying 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.
