Title: The Innovations of Donald R. Jansta
Introduction
Donald R. Jansta is a notable inventor based in Waukesha, WI (US). He has made significant contributions to the field of medical imaging technology. His work primarily focuses on enhancing magnetic resonance imaging (MRI) systems through innovative designs and applications.
Latest Patents
One of Jansta's key patents is the "Fiber optic photoplethysmograph for a magnetic resonance imaging system." This invention involves a magnetic resonance imaging system equipped with an electromagnet coil assembly that excites the nuclei of an animal placed within the assembly. The system includes a mechanism to receive magnetic resonance signals from the nuclei and reconstruct an image of the animal. A plethysmograph is integrated to sense the peripheral arterial pulse of the animal, which helps gate the MRI system. The sensor for the plethysmograph utilizes a fiber optic cable with a pair of optical fibers extending into the magnet assembly. A probe connected to one end of the cable is designed to attach to a digit of the animal, ensuring that the ends of the optical fibers are adjacent to the animal's skin. The other end of the cable connects to a circuit that sends light through one optical fiber to the probe and receives light returned from the probe through the other optical fiber. The circuit then produces an electrical signal corresponding to the intensity of light received.
