摘要：

PROBLEM TO BE SOLVED: To provide an image processor capable of improving extraction accuracy.

SOLUTION: A storage part 10 stores time-sequential volume data relating to a scanning area. An operation part 22 specifies a start point according to an instruction from a user on an extraction object area within the scanning area. A time-density curve generation part 12 generates a first time-density curve relating to the start point, a second time-density curve relating to an object point within the scanning area, and a third time-density curve relating to a reference point positioned near the object point and connected to the start point on the basis of the time-sequential volume data. A determination part 14 determines whether or not the object point belongs to the extraction object area on the basis of the second time-density curve and at least one of the first time-density curve and the third time-density curve. An extraction part 16 does not use the object point as an extraction object when determined that the object point does not belong to the extraction object area, and uses the object point as the extraction object when determined that the object point belongs to the extraction object area.
