Patent ID: 8542793

Claim:
A method for measuring a sample pore using a computed tomography (CT) and a standard sample comprising: an operation signal transmitting step S 100 of transmitting operation signals to a sample rotating motor by means of an operation signal transmission unit to rotate a sample rotating device and transmitting a CT beam transmission signal to a CT beam transmission unit; a sectional image acquiring step S 200 of acquiring sectional images of a standard sample and a measurement sample analyzed by a detector by means of an image acquisition unit 520 ; a sectional image storing step S 300 of storing the sectional images acquired by the image acquisition unit in an image storage unit; and a measurement sample porosity calculating step S 400 of acquiring a count range and a gray level range of a pore from the sectional images of the standard sample, which are stored in the image storage unit, by means of a central control means and calculating the number of pixels in the count range of the sectional image of the measurement sample and the number of pixels corresponding to the gray level range of the pore with reference to the count range of the sectional images and the gray level range of the corresponding pore by means of the central control means so as to measure the porosity of the measurement sample.
