First Major CT Imaging Advancement in Nearly a Decade Cleared by US FDA

By News Release

The US FDA cleared the first new major technological improvement for Computed Tomography (CT) imaging in nearly a decade.

The device, Siemens NAEOTOM Alpha, uses the emerging CT technology of photon-counting detectors which can measure each individual X-ray that passes through a patient's body, as opposed to current systems which use detectors that measure the total energy contained in many X-rays at once. By ‘counting’ each individual X-ray photon, more detailed information about the patient can be obtained and used to create images with less information that is not useful in the review and analysis.

“Computed tomography is an important medical imaging tool that can aid in diagnosing disease, trauma or abnormality; planning and guiding interventional or therapeutic procedures; and monitoring the effectiveness of certain therapies,” said Laurel Burk, Ph.D., assistant director of the Diagnostic X-ray Systems Team in the FDA’s Center for Devices and Radiological Health. “Today’s action represents the first major new technology for computed tomography imaging in nearly a decade and underscores the FDA’s efforts to encourage innovation in areas of scientific and diagnostic progress.”

The new diagnostic imaging device is designed to transform the information from X-ray photons that pass through a patient's body, and are received by a detector, into a detailed 3-dimensional image. The images delivered by the system can be used by a trained physician as an aid in diagnosis or can be used by trained staff as an aid in diagnosis, treatment preparation and radiation therapy planning.
