Abstract

Recently developed new step wedge has a small size as $10{\times}10\;cm^2$. It can use central beam, and is affected little by scattered rays emmitted from the neighboring step wedges. It's characteristics are same as the intensity scale method, and are excellent compared with conventional boot strap methods. Moreover, the method using new step wedge is simple in operation, and the characteristics are excellent. Now, the above method using new step wedge can supercede the distance method.
