Summary
This study introduces an adaptive field of view (FOV) method to reduce magnetic resonance imaging (MRI) scan times. The technique optimizes FOV based on initial scans, cutting acquisition time by 9-14% without extra hardware.
Area of Science:
- Medical Imaging
- Radiology
- Biomedical Engineering
Background:
- Magnetic Resonance Imaging (MRI) acquisition time is a critical factor.
- Volume imaging often acquires data outside the region of interest, wasting time.
- Reducing MRI scan duration is essential for patient comfort and throughput.
Purpose of the Study:
- To present a novel method for reducing MRI scan time.
- To implement an adaptive field of view (FOV) technique.
- To improve image resolution and reduce scan duration simultaneously.
Main Methods:
- Acquiring multislice MRI images with an adaptive FOV.
- Determining slice FOV in the phase encoding direction using initial localization scans.
- Optimizing FOV based on the specific region of interest.
Main Results:
- Achieved typical scan time reductions of 9-14%.
- The adaptive FOV method requires no additional hardware.
- The technique is simple to implement in clinical MRI workflows.
Conclusions:
- Adaptive FOV is an effective strategy for MRI scan time reduction.
- This method enhances efficiency without compromising image quality.
- The approach offers practical benefits for routine MRI examinations.
