Coil Array and Its Use

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a novel coil array for use in magnetic resonance imaging (MRI) systems. The unique feature is that at least one coil element is bent and open (not a closed loop), allowing easy passage of tubes or cables for patient supplies (such as anesthesia or breathing apparatus) to reach the subject being imaged. This design maintains high image quality and accessibility, which is especially important for imaging infants, young children, animals, or other small subjects.

Use CasesContent extracted from patent full text and abstract with AI.

• MRI scans of infants, neonates, or small children, especially in situations requiring access for anesthesia or other life-support lines.
• Imaging of animal models or small biological samples in preclinical research where physical access is needed during scanning.
• Integration in MRI-compatible neonatal incubators, allowing continuous monitoring or treatment of newborns without compromising image quality.
• Specialized head or body MRI studies for patients who require multiple monitoring or support devices during imaging.

BenefitsContent extracted from patent full text and abstract with AI.

• Improved access for life-support tubes, cables, and other monitoring/treatment devices during MRI procedures, especially for vulnerable patients like infants.
• Higher signal-to-noise ratio and better image quality compared to standard coil arrays, even with access lines present.
• Reduced electromagnetic field inhomogeneity (Bo-shimming problems) near air-filled cavities (like the nasal sinuses), improving image consistency.
• Flexibility to effectively image smaller anatomical regions while maximizing the filling factor, leading to significant improvements in sensitivity and image resolution.
• Reduces the need for oversized coils and the associated decrease in sensitivity when imaging small objects or pediatric patients.
• Enables safer and more effective MRI imaging in critical care situations, such as for neonates on life support.
