Inspection method of radiation imaging system and medical image processing apparatus using the same, and phantom for use of inspection of radiation imaging system

A medical image processing apparatus for evaluating image quality of a radiation image obtained by using a radiation imaging system which performs radiation imaging to record radiation image information on a recording medium, reads out the radiation image information from the recording medium to generate image data, and performs a predetermined image processing for the image data to display or output a radiation image, thereby inspecting said radiation imaging system, said medical image processing apparatus comprising:

• image processing means for performing image processing on input image data;
• measuring means for performing, when image data representing a radiation image obtained by imaging a phantom having a plurality of image quality evaluating patterns as to a predetermined image quality evaluation item is inputted, measurement with respect to the input image data as to said predetermined image quality evaluation item;
• inputting means to be used for inputting inspection result as to said predetermined image quality evaluation item obtained by visually observing the displayed or outputted radiation image;
• and
• determination means for determining the image quality of said radiation image on the basis of measurement result obtained by said measuring means and the inspection result inputted by using said inputting means.
