Title: The Innovations of Donald S. Kearns in Nuclear Cardiology

Introduction

Donald S. Kearns, based in Farmington, CT, is a notable inventor with a focus on advancements in nuclear cardiology. With two patents to his name, Kearns has made significant contributions in the field, particularly through his innovative methodologies that enhance cardiac evaluations using nuclear imaging techniques.

Latest Patents

Kearns’ latest patent is a groundbreaking system described as "Emissive Computed Tomography - Nuclear Cardiology Apparatus and Method." This invention is designed specifically to assess cardiac function by utilizing a scintillation camera that measures radiation variations from a patient’s heart post-administration of a radioactive tracer. The system is ingeniously crafted to provide real-time data, segregating counts that correspond to radiation from predetermined regions of the heart, notably the left ventricle. By synchronizing these measurements with the patient’s electrocardiogram, Kearns’ system employs time-gated memory circuitry to partition each heartbeat into subintervals, allowing for precise tracking of radiation events within defined regions of interest. This innovation enables the calculation of blood ejection fractions during each heartbeat, further facilitated by a strip chart recorder that provides a permanent representation of the radiation curve from the heart.
