Radiation therapy firm Varian Medical Systems received U.S. Food and Drug Administration (FDA) registration for its Claymount Optica 20 and Optica 40 collimators.
The collimators are used to narrow the focus of x-ray beams in film-based and digital radiography (DR) systems for improving image quality and minimizing dose to patients, the firm said.
The manually operated Optica 20 collimator is designed for use in human and veterinary radiography systems, and it can be installed into new or existing imaging systems. The motorized Optica 40 collimator is intended for human radiography and fluoroscopy imaging systems. When integrated with the software of the x-ray system, Optica 40 can be used to remotely adjust the x-ray beam collimator, Varian added.
The Optica collimators are lightweight with a range of filtration options, including the ability to prevent patients from being exposed to low-energy x-ray spectrums and to meet requirements for pediatric imaging.
