Title: Alasdair Stewart Hall: Innovator in Magnetic Resonance Technology
Introduction
Alasdair Stewart Hall is a notable inventor based in Northwood, GB. He has made significant contributions to the field of magnetic resonance technology, holding 2 patents that enhance medical imaging techniques. His work focuses on improving the quality and efficiency of magnetic resonance imaging (MRI) procedures.
Latest Patents
One of Hall's latest patents is an "Injector for injection of pre-polarised fluid into a patient for magnetic resonance (MR) measurement." This invention involves a patient bed of an MR imaging apparatus equipped with a tube that allows for the injection of pre-polarised fluid. This fluid improves contrast when imaging veins, arteries, or other vessels in the body. The fluid is delivered from a pump into a high field polarising magnet and along a tube to the patient. A valve is included to discard fluid downstream of the pre-polarised fluid, ensuring that the magnetisation of the injected fluid remains intact for optimal imaging results.
Another significant patent is related to "Coil arrangements in magnetic resonance apparatus." This invention features an RF coil arrangement that produces a static magnetic field for application to a body under examination. The RF coil arrangement includes at least one coil with a first part fixed to the apparatus and a further part that is detachably connected. This design allows for easy access to the gap when placing or removing a body to be imaged, enhancing the user experience and efficiency of the imaging process.
