Bleepa is based on Feedback's Cadran technology, which allows medical staff to securely view and discuss high-quality medical grade images on mobile devices.
It will be showcased at the NHS Expo in Manchester on Wednesday and Thursday (Sept 4-5).
"We are demonstrating Bleepa for the first time at Expo with leaders who are driving digital innovation across the NHS,” said Feedback chief executive, Dr Tom Oakley.
“The role of digital technology in revolutionising patient care is central to the NHS Long Term Plan and we believe Bleepa sits firmly at the heart of this movement, enabling clinicians to share high-quality medical images and discuss how to give the best possible patient care securely and quickly via mobile devices."
All manner of images
The Feedback-developed system can display images including X-rays, CTs, MRIs and ultrasounds, allowing users to easily scroll through image slices and annotate areas of interest.
Questions can be asked alongside notes and submitted into the chat where they can be securely reviewed by colleagues at the swipe of a finger.
Currently, it is only possible to view medical grade images on desktop computers and discuss them by telephone.
According to a recent British Medical Journal study, 97% of hospital doctors routinely use WhatsApp to communicate about patients.
Convenience means physicians will often use their own hand-held devices to share information and images.
But poor picture quality makes it difficult for proper decision-making, while there are obvious data risks sharing via common apps.
