摘要：
A specific site location measuring includes: calculating matching degrees based on a plurality of transmission images imaged by use of radiation transmitting through a specimen and a template set; selecting a template transmission image from the plurality of transmission images based on the matching degrees; adding a new template generated based on the template transmission image, to the template set; imaging a location measurement transmission image by use of radiation transmitting through the specimen; selecting an optimal template that is the most similar to a portion of the location measurement transmission image, from the template set by performing pattern matching of each of templates of the template set with the location measurement transmission image; and calculating a specific site location based on the location measurement transmission image and the optimal template.
