High Voltage and Radiofrequency Capacitors and Metallized Ceramics Designed for Radiology and Medical Applications

A range of high voltage (HV) and radiofrequency (RF) capacitors used in X-ray generators, along with a range of metallized ceramics and assemblies used in X-ray tubes, computed tomography (CT) scanners, and magnetic resonance imaging (MRI) systems for radiology and medical applications are to be presented at the 100th annual meeting of the Radiological Society of North America (RSNA) in Chicago (IL, USA), from November 30 to December 5, 2014.

Made from Morgan Advanced Materials (Windsor, UK) 36 and K77 dielectric components, the high power HV and RF capacitors are nonmagnetic, making them suitable for use in medical imaging equipment. Furthermore, the capacitors demonstrate low electrical loss and have a high dielectric strength to enable them to carry high electrical loads over a wide frequency range. They can also be custom-designed for the precise tuning of MRI scanners.

Offering high mechanical strength, vacuum integrity, and good thermal conductivity, Morgan’s range of metallized components include RF windows, medical linear accelerator metallized rings and high power insulators for cyclotrons. Moreover, its high voltage feed-throughs have been precisely engineered to maintain very high levels of vacuum and joint integrity via a robust hermetic seal, ideal for extreme operating conditions from elevated temperatures to cryogenic conditions.

Joerg-Uwe Wichert, from Morgan Advanced Materials, commented, “The components, assemblies and solutions developed by Morgan are used throughout the spectrum of radiology, from diagnosis to treatment, and are centered on assisting medical OEMs [original equipment manufacturers] to deliver the best in care to cancer patients. From improving the longevity and service life of diagnostic radiography tools to improving the accuracy and safety of drug delivery, it’s possible to find a Morgan solution at every stage of the oncology pathway.”

An extensive range of air-in-line sensors for the detection of air bubbles in medical dosing equipment will also be presented at the RSNA meeting. The sensors enable increased control over the detection of air bubbles in liquids which, if undetected, could impede the functioning of drug delivery systems or allow bubbles to enter the patient’s bloodstream—a potentially fatal consequence. Enhanced air-in-line (AIL) sensors allow the detection of the size of air bubbles in tubes, meaning sensors can be easily configured for different applications.

Morgan Advanced Materials is a global materials engineering company that designs and manufactures a wide range of high specification products with enhanced properties, across multiple sectors and geographies. The engineered solutions are produced to very high tolerances, and many are designed for use in extreme environments.
