Latest Patents
Fitzsimmons holds several noteworthy patents, two of which stand out for their innovative approaches to NMR imaging.
1. **Continuously Variable Field of View Surface Coil for NMR Imaging:** This patent introduces an NMR radio frequency (RF) surface coil that allows users to variably adjust the size of the field of view consistently. The design incorporates a modified radio frequency trombone for easy size adjustment, ensuring a stable resonant frequency across a wide range of dimensions. This advancement allows for an increased area of the coil by up to 60%, maintaining frequency stability up to 1 MHz at 63.5 MHz and 2 MHz for a full extension of 10 cm. This coil is primarily adapted for imaging the human spine but can also be implemented in imaging various anatomical features.
2. **Cross-Coupled Double Loop Receiver Coil for NMR Imaging of Cardiac and Thoraco-Abdominal Regions:** This invention presents an RF receiver coil structure uniquely designed for imaging the thoraco-abdominal and cardiac areas of the human body. The structure features a generally solenoidal geometry coil composed of two turns with an inter-element gap large enough to accommodate an average human torso. Cross-coupled by diagonal elements, the coil is formed from a tubular conductor and is designed with a capacitor to create a parallel resonant circuit. This innovative coil configuration may also extend to a multi-turn structure, optimizing the imaging process by positioning turns above and below the patient.
