Title:
METHOD AND APPARATUS FOR DETERMINING BREATHING CYCLE OF PATIENT
Document Type and Number:
Japanese Patent JPS61143035
Kind Code:
A
Abstract:
A method for eliminating or reducing breathing artifacts due to motion-induced phase and amplitude errors in the phase-encoding dimension when using Fourier transform imaging methods, such as spin warp, utilizes a repetition time (TR) which is an odd multiple of one quarter of the breathing cycle. In the preferred embodiment, method and apparatus are provided for determining the breathing cycle by monitoring the integrated spin-echo signal magnitude spectrum as a function of time.
