CE Mark For Software That Improves X-Ray Reading

In short

As we pointed out yesterday, this week sees the 2012 Radiological Society of North America (RSNA) annual meeting in Chicago. Riverain Technologies has taken the opportunity to publicise the fact that its new ClearRead +Confirm™ software has gained CE mark approval. Riverain says its software improves the visual clarity of conventional chest X-ray images and increases radiologists’ efficiency by reducing the time it takes to accurately confirm the proper placement of lifesaving feeding, drug-delivery and pain management tubes and lines.


Tubes and lines placed inside the body are used regularly for intensive care patients and others receiving ongoing treatments for cancer, pain and other conditions. Improper placement or migration of the devices between uses can cause serious complications, including death.

Portable chest X-ray machines are routinely used to confirm placement of lines and tubes; however, the image quality makes it challenging for radiologists to differentiate these structures, and the rib and clavicle bones obscure visibility of chest tissue by up to 40 percent. Radiologists also incur significant time adjusting the image to make the edges and tips of the devices stand out.

Riverain technologies has issued a press release in which it states that ClearRead +Confirm™ software immediately processes any portable chest X-ray, creating a second, soft tissue image with the ribs and clavicles suppressed and increasing the contrast, sharpness and visibility of tubes, lines and cardiac wires. Radiologists simply toggle between the two images to confidently and efficiently confirm proper placement of the devices.

In a study at Georgetown University, 334 chest X-rays were reviewed by 10 radiologists with and without the enhanced ClearRead +Confirm image. The software reduced the reading time by an average of nearly 19 percent, without comprising accuracy.

Evaluating the conventional X-ray and ClearRead image together took an average of 5 ½ seconds less per image than evaluating the conventional X-ray image on its own, amounting to a savings of 30 minutes across all images.

Company comments

“The software-enhanced chest X-ray image increases radiologists’ confidence while reducing decision-making time and time to treatment, with no additional tests or radiation exposure for patients,” said Steve Worrell, Riverain’s Chief Technology Officer.
