Title:
MAGNETIC RESONANCE IMAGE PICK-UP DEVICE
Document Type and Number:
Japanese Patent JP3403751
Kind Code:
B2
Abstract:
PURPOSE: To shorten the reconstitution time of an image by collecting the data in one specific axis direction and in a specific polarity direction, inverse Fourier transformation-treating the data in the axis direction other than the specific axis, generating the data in other polarity direction in one specific axis and inverse Fourier transformation-treating the synthesized data.
CONSTITUTION: The nuclear resonance data row in a specific axis direction among X, Y, and Z axes and in a specific polarity direction is collected from an inspected body on which the static magnetic field, gradient magnetic field and the high frequency pulse are applied (Step 31). Then, the MR image in the specific region of the inspected body is reconstituted from the collected magnetic resonance data row (Step 32). Accordingly, the collected magnetic resonance data row is inverse Fourier transformation-treated in the axial direction other than the specific axis (Step 33). Then, all the data on the (k) space is synthesized from the data obtained in the Step 33 and the complicated conjugate data (Step 34). Then, the synthesized data is inverse Fourier transformation- treated in the specific one axis direction (Step 35). Accordingly, the reconstitution time can be shortened.
