Radiation Reduction

ROI Radiation Reduction

ROI technology is proven to substantially reduce patient radiation dose outside of the ROI while maintaining – or improving – image quality within the ROI. Omega AI image-guided ROI systems bring this proven science to reality by dynamically collimating to the ROI – leveraging AI, an ultra-fast collimator, and the world’s most advanced image processing.

Region of interest (ROI) imaging is used to substantially reduce patient dose outside of a ROI while maintaining or improving image quality within the ROI.

In some medical-imaging procedures such as fluoroscopy, only the center of the field of view (FOV) may be needed to be visualized with optimal image quality – to reduce the dose to the patient while maintaining visualization of the entire FOV, an aperture for the region of interest (ROI) is used with a substantial reduction of dose when using an ROI during procedures.

Noise-reduction techniques in combination with ROI fluoroscopy have the potential for substantial patient-dose savings in cardiac interventions.

A combination of ROI fluoroscopy where exposure is substantially reduced in the peripheral region outside the ROI and image processing enables patient does savings along with improved image quality.

Methods and Technologies to Reduce Radiation

Radiation protection aims to reduce unnecessary radiation exposure with a goal to minimize the harmful effects of ionizing radiation with three basic principles – justification, optimization, and dose limitation.

Frequently asked questions by health professionals with respect to good practices in interventional fluoroscopy as presented by Radiation Protection of Patients (RPOP) at the IAEA.

Proper training of fluoroscopic operators, understanding the factors that influence radiation dose, and use of various dose reduction techniques may allow effective management of patient dose.

A radiation reduction protocol with a low frame rate and selective fluorography storage was effective at reducing radiation by about 21% during PCI.

This report discusses basic policies and procedures employed at Hospital for Special Surgery (HSS) to assure ionizing radiation safety and security of patients undergoing imaging examination/procedures and for the employees providing these services.
