Filed: 1994-02-08
Abstract: PURPOSE: To quickly calculate the maximum intensity projection by calculating interpolated gray levels for points along a beam of light and deciding the maximum of the interpolated gray levels for assigning the values to pixels related to the beam of light. CONSTITUTION: An arithmetic means decides an estimated minimum gray level for each beam of light 61 and an estimated maximum gray level for each Pk of a plurality of points P1 -Pm provided along the beams of light 61 and extracts the maximum gray level from the values of voxels in prescribed adjacent parts around the points Pk . The arithmetic means compares the estimated maximum gray level with the estimated maximum gray level for the beam of light 61 and, when the estimated gray level for the points Pk exceed the estimated minimum gray level, calculates the interpolated gray level for the point Pk along the beams of light 61. Then, the maximum of the interpolated gray level is decided for the allocation for the pixels related to the beam of light 61. Since the values obtained as a result of interpolation are not gray levels, arithmetically expensive interpolation can be omitted.
