Title: Innovations of David M Kramer

Introduction

David M Kramer is a prominent inventor based in San Rafael, California. He holds a total of 14 patents, showcasing his significant contributions to the field of magnetic resonance imaging (MRI). His work has advanced the technology used in medical imaging, particularly in the areas of diffusion imaging and the compensation of eddy currents.

Latest Patents

One of his latest patents is a fast spin echo MRI method compatible with CPMG violation. This innovative technique provides a fast spin echo imaging method that is insensitive to violations of the Carr Purcell Meiboom Gill (CPMG) condition. The method involves splitting spin echoes into echo pairs, allowing for the construction of two independent images that can be combined to form a final image. This approach enhances the accuracy of diffusion measurements and diffusion-weighted imaging.

Another notable patent is the method and apparatus for diffusion magnetic resonance imaging with the effects of eddy currents compensated. This system acquires diffusion magnetic resonance images while compensating for the effects of eddy currents induced by diffusion weighting gradient pulses. By utilizing prescan data to model eddy current parameters, the imaging sequence is modified to ensure accurate image acquisition.
