Balter Medical AS (BM) was established in Bergen, Norway in 2001 by Prof. Jakob J. Stamnes and Prof. Knut Stamnes. Its purpose is to develop and commercialise medical applications of Optical Transfer, a mathematical modelling technique applied to digital photographic images of tissue to improve the understanding of tissue properties.

BM has successfully developed a medical imaging device (BM-Dermatoscope) and a diagnostic algorithm [Optical Transfer Diagnosis (OTD)] for detecting anomalies in human tissue.  The first BM-OTD application is a device and an algorithm to assist in the diagnosis of skin cancer, particularly melanoma.

BM-Dermatoscopes are currently being used in tele-dermatology services in France and UK; we expect the associated Balter Diagnostic Indication Algorithm (BDIA) to be available in 2021 following a large-scale international pivotal trial. BDIA will give the user a diagnostic indication in real-time.

The BM-OTD technology is completely safe and non-invasive, and no pre-treatment is required.

The BM-OTD technology may be applied in many clinical diagnostic procedures where the naked eye or simple photographic imaging is not sufficient to obtain an accurate diagnosis, especially suitable for skin or near-surface internal examinations and surgeries.

The BM-OTD is a platform technology that can be applied to a broad array of optical diagnostic instruments for tissue characterization in multiple organ systems. In addition, cosmetic, forensic, and industrial applications are possible.

Future medical applications may include endoscopy mounting of the camera for the interrogation and diagnosis of internal tissue abnormalities such as in lungs, the gastrointestinal (GI) tract, the esophagus, as well as oral and cervical mucosal membranes.
