**2.2 Telemedicine between health care providers**

This telemedicine is conducted primarily between the physician in charge and medical specialist and is referred to as "narrow sense telemedicine."

Besides, it is mainly classified into teleradiology, telepathology, teledermatology, and telepsychiatry. In WHO report, each field is defined as follows.


Of the four fields of telemedicine that were highlighted in the survey, teleradiology has the highest rate of established service provision. Teleradiology is built on the medical ICT system of diagnostic imaging studies from one location to another for conferences or consultations.

*Rapid application development system (RAD) developed by ViewSend ICT. ViewSendRAD provides a real-time 3-in-1 telemedsolution for telemedicine, tele-radiology, and videoconferencing. This product is designed to be a real-time software solution –collaboration, consultation, or training. These functions were advantageous to sharing information and deepening understanding of imaging data in the joint research.*

In Japan, the teleradiology system is well used to support underserviced hospitals in the depopulated area to have timely access to a radiologist. Recent telemedicine research has developed the system that integrates functions of telemedicine and video conference (**Figure 1**).
