Title: Innovations of David B Van Hulsteyn

Introduction

David B Van Hulsteyn is a notable inventor based in Santa Fe, NM (US). He has made significant contributions to the field of superconductive imaging and nuclear magnetic resonance (NMR) imaging. With a total of 2 patents, his work has advanced the capabilities of imaging technologies.

Latest Patents

One of his latest patents is the Superconductive Imaging Surface Magnetometer. This invention features an improved pick-up coil system designed for use with Superconducting Quantum Interference Device (SQUID) gradiometers and magnetometers. It incorporates superconducting plates near conventional pick-up coil arrangements, enabling imaging of nearby dipole sources while deflecting environmental magnetic noise. This innovation allows for gradiometry and magnetometry in magnetically unshielded environments. One embodiment of this invention utilizes a hemispherically shaped superconducting plate with interior pick-up coils, facilitating brain wave measurements on human patients. Another embodiment employs flat superconducting plates for non-destructive evaluation of materials.

His second patent, Polarization Transfer NMR Imaging, involves obtaining a nuclear magnetic resonance (NMR) image with spatial information modulated by chemical information. This modulation is achieved through polarization transfer from a first element, which represents the desired chemical information, to a second element that provides the imaging data. The process includes applying first and second radio frequency (rf) pulses at different frequencies to excite the imaging and functional elements, with imaging gradients applied to spatially separate the nuclei response for imaging. This technique allows for the imaging of metabolic processes involving compounds such as glucose, lactate, or lactose, labeled with ¹³C, utilizing the sensitivity of ¹H and the selectivity of ¹³C.
