Title:
MR METHOD FOR TWO- OR THREE-DIMENSIONALLY IMAGING EXAMINATION AREA AND DEVICE FOR CONDUCTING SAID METHOD
Document Type and Number:
Japanese Patent JPH06296599
Kind Code:
A
Abstract:
PURPOSE: To improve the time and space resolution by forming auxiliary data from two sets of raw data and obtaining auxiliary data through the same measurement parameter and at different instants or through different measurement slices, and producing image obtained through interpolation from the raw data thus obtained. CONSTITUTION: The received MR signal is amplified by a unit 20 and transmitted to base band. The obtained analogue signal is transformed into a digital sequence by an analogue-digital transformer 21. The analogue-digital transformer 21 is followed by a Fourier transformation unit 22 performing the one dimensional transformation for the sequence of sampling value. The raw data produced by Fourier transformation is written into a memory 23. An interpolation unit 24 forms sets of auxiliary data stored by a memory 25 from the sets of raw data. These sets of auxiliary data are calculated at different instants, and a reconstructing unit 26 produces MR image from the sets of raw data.
