Breath-hold monitor for MR imaging |
摘要 |
In an NMR system a respiration monitor provides a visual feedback to the patient which enables the patient to perform a series of breath-holds with the patient's diaphragm positioned at the same reference point. This enables NMR data to be acquired over a series of breath-holds without introducing blurring or image artifacts. Between breath-holds a navigator pulse sequence is used to gather NMR data from which diaphragm position is measured, and during each breath-hold the pulse sequence is changed to gather NMR image data.
