Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To accurately and quickly measure the shape of a tooth fang whose content of resonant substance is lesser and can not be measured directly by an MRI device. SOLUTION: A tooth fang to be measure is covered with an MRI contrast medium 8 containing a great quantity of hydrogen atoms and fluorine atoms capable of making resonance, and the three-dimensional shape of the contrast medium 8 is measured by an MRI device, which is equipped with two transmitting means 12 to put the hydrogen atoms and fluorine atoms in resonance and with two signal receiving means 13 to receive their resonance frequencies f1, f2. Linear data due to distribution of the hydrogen atoms is acquired from the resonance frequency 41 received by one of the receiving means 13, while linear data due to distribution of the fluorine atoms is acquired from the resonance frequency f2 received by the other receiving means 13.  Because two pieces of lines data are acquired through one run of measuring operation, the three-dimensional shape of the contrast medium 8 can be measured in a time half of conventional. The surface shape of the fang can be measured from the shape of the contrast medium 8 contacting with the fang.
