<p><P>PROBLEM TO BE SOLVED: To increase the accuracy of a slice position while saving time and labor for an operator as much as possible. <P>SOLUTION: Data of a coronal image IC is Fourier-transformed in the z axial direction, and a frequency spectrum FS is created. Then, the interval SP of the intervertebral disks of a subject is calculated on the basis of the frequency spectrum FS. After calculating the interval SP (=SP<SB POS="POST">0</SB>) of the intervertebral disks, the interval of a plurality of landmarks owned by a reference model of the cerebrospinal fluid is adjusted on the basis of the calculated interval SP of the intervertebral disks, and the reference model MC of the cerebrospinal fluid for which the interval of the landmark M<SB POS="POST">i</SB>has been adjusted is changed according to the cerebrospinal fluid of the subject. Then, a signal strength profile is created by displacing each of landmarks M<SB POS="POST">1</SB>to M<SB POS="POST">x</SB>, and a reference point for positioning the slice position of the intervertebral disk is set on the basis of the signal strength profile. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
