Medical device firm ControlRad Systems is highlighting a new study published in Medical Physics that found radiation reductions of about 75% with the use of its product in fluoroscopy-guided interventional procedures.
The study used ControlRad's eye-tracking technology to reduce the radiation dose to both patients and operators, without affecting performance of the procedure, the company said.
The results were achieved by allowing the fluoroscopy operator to optimize the x-ray beam using the eye-tracking technology, without compromising either image quality or workflow. In fact, the technique produced a subjective enhancement of perceived visualization, ControlRad said.
In the demonstration study in a swine model, with the ControlRad technology, most of the 30-cm field-of-view was irradiated to less than 20% of normal levels, while the clinical region of interest was normally irradiated. When the technology was engaged, radiation to the patient and operator decreased by approximately 75% as measured by kerma-area product and other methods, according to the group led by Stephen Balter, PhD, from Columbia University (Med Phys, March 2016, Vol. 43:3, pp. 1531-1538).
The results validate the clinical utility and potential benefits of the technology, ControlRad said. By giving operators complete control of the x-ray beam, they are able to optimize it in the region of immediate clinical interest, reducing the dose delivered to the patient and operator.
