The document describes TeleMaster, a telemedicine platform that provides remote diagnostic services. It can be used to create centralized medical call centers or allow physicians to provide remote diagnostic services from their clinics. TeleMaster securely transfers medical data, manages diagnostic workflows and queues, and allows remote diagnosis using various medical devices. Case studies demonstrate how it has been used in Israel to reduce costs and improve efficiency at a cardiology call center processing over 18,000 Holter readings per year and to remotely monitor over 2,000 congestive heart failure patients through home monitoring devices. It has also been used in India on a project with over 51,000 medical kiosks enabling virtual patient-physician encounters.
