MEDICAL IMAGE DISPLAY CONTROL APPARATUS AND OPERATION METHOD OF THE SAME, AND MEDIUM

摘要

Providing a parameter calculation unit that calculates parameters representing medical functional information for pixel positions of the medical image, wherein the upper and lower limit values of the parameter medically represent the same functional information and whose value changes cyclically between these values, an interpolation parameter calculation unit that obtains, for a pixel position for which the parameter is not calculated, a parameter by interpolation, the unit calculating a parameter obtained by the interpolation using a cyclic function in which the interpolation direction differs according to the difference between the parameters calculated for two pixel positions, a display color group storage unit that includes a color group in which the same color corresponds to the upper and lower limit values of the parameter and whose color changes with the magnitude of the parameter, and a mapping unit that maps the parameters based on the color group.

1. A medical image display control apparatus, comprising:
a parameter calculation unit that calculates, using a medical image, parameters representing medical functional information for at least two pixel positions of the medical image, wherein the upper limit value and the lower limit value of the parameter medically represent the same functional information and whose value changes cyclically between the upper limit value and the lower limit value; an interpolation parameter calculation unit that obtains, with respect to a pixel position for which the parameter is not calculated, a parameter from the parameters calculated for the at least two pixel positions by interpolation, the unit calculating a parameter obtained by the interpolation using a cyclic function in which the interpolation direction differs according to the difference between the parameters calculated for the at least two pixel positions; a display color group storage unit that includes a color group in which the same color corresponds to the upper limit value and the lower limit value of the parameter and whose color changes with the magnitude of the parameter; a mapping unit that performs mapping of the parameters based on the color group; and a display control unit that displays the mapped color image.
