ABSTRACT=Purpose: To design a “low cost” tele-imaging method allowing real time tele-ultrasound expertise, delayed tele-ultrasound diagnosis and tele-radiology between remote peripherals hospitals and clinics (patient centres) and university hospital centres (expert centre).

Materials and Methods: A system of communication via internet (IP camera and remote access software) enabling transfer of ultrasound videos and images between two centres, allows a real time tele-radiology expertise in the presence of a junior sonographer or radiologist at the patient centre. In the absence of a sonographer or radiologist at the patient centre, a 3D reconstruction program allows a delayed tele-ultrasound diagnosis with images acquired by a lay operator (e.g. midwife, nurse, technician). The system was tested both with high and low bandwidth. The system can further accommodate non-ultrasound tele-radiology (conventional radiography, mammography and computer tomography for example). The system was tested on 50 patients between CHR Tsevie in Togo (40km from Lomé-Togo and 4500km from Tours-France) and CHU Campus at Lomé and CHU Trousseau in Tours.

Results:  A real time tele-expertise was successfully performed with a delay of approximately 1.5 seconds with an internet bandwidth of around 1Mbps (IP Camera) and 512kbps (remote access software). A delayed tele-ultrasound diagnosis was also performed with satisfactory results. The transmission of radiological images from the patient centre to the expert centre was of adequate quality. Delayed tele-ultrasound and tele-radiology was possible even in the presence of a low bandwidth internet connection. 

Conclusion: This tele-imaging method, requiring nothing by readily available and inexpensive technology and equipment, offers a major opportunity for telemedicine in developing countries.
