The Need

Medical imaging plays a crucial role in diagnosing various diseases and conditions. Magnetic Resonance Imaging (MRI) has emerged as one of the most significant and preferred medical imaging modalities due to its non-invasive nature and low risk of side effects compared to other imaging methods involving ionizing radiation exposure. With the increasing demand for high-quality MRI scans worldwide, there is a pressing need for advanced technologies that can optimize MRI protocols, enhance image quality, and improve detection sensitivity of pathophysiological changes. Addressing these needs is essential for accurate diagnoses and effective medical treatment.

The Technology

The technology described herein focuses on the optimization of MRI protocols, imaging parameters, k-space strategies, and RF system calibration to achieve superior image quality and sensitivity. By simulating signal intensity and contrast using Bloch equations with tissue MR parameters, the technology provides initial imaging parameters that serve as a foundation for further optimization. The method also optimizes k-space strategies, filling the k-space center with the line that maximizes contrast, and minimizing image artifacts. Additionally, RF system calibration is performed to reduce variability caused by hardware systems and correct inhomogeneous contrast resulting from non-uniform transmit field and receiver sensitivity.
