Title: The Innovative Mind of Richard Frayne: Advancements in Magnetic Resonance Angiography
Introduction
Richard Frayne, based in Madison, WI, has made significant contributions to the field of medical imaging through his inventive spirit and technical expertise. With a total of five patents to his name, he is recognized for pushing the boundaries of magnetic resonance angiography (MRA), instrumental in improving diagnostic techniques in healthcare.
Latest Patents
Among Richard Frayne's most notable patents is a pioneering method for time-resolved digital subtraction magnetic resonance angiography. This innovative technique utilizes a dynamic MRA study with a three-dimensional echo-planar imaging pulse sequence. By acquiring four phase encoding views for each pulse repetition period, it enables the capture of higher resolution images without sacrificing the temporal frame rate or image contrast-to-noise ratio (CNR).
Another significant patent involves digital subtraction magnetic resonance angiography with image artifact reduction. By performing a dynamic MRA study using a three-dimensional fast gradient-recalled echo pulse sequence, Frayne's approach increases the frame rate of the reconstructed images. This is achieved by sampling a central region of k-space more frequently than the peripheral regions, effectively minimizing artifacts caused by signal strength variations as the contrast agent enters the region of interest. The reconstruction of 2D image frames from planes near the center of k-space provides operators with the flexibility to select optimal 3D datasets for diagnostic imaging.
