BACKGROUND Tuberculosis (TB) is still a leading cause of death worldwide. Almost a third of the world's population is infected with TB bacilli, and each year approximately 8 million people develop active TB and 2 million die as a result. Today's TB treatment, which dates back to the 1970s, is long and burdensome, requiring at least 6 mo of multidrug(More)
A master-slave type remote ultrasound diagnostic system was developed. The controller has impedance control capability for the master and slave manipulators' positions. And it has a Continuous Path(CP) control capability for the slave manipula-tor's orientation. This paper presents the controller of the slave manipulator's orientation. The remote(More)
A master-slave type remote ultrasound diagnostic system was developed. This paper presents its controller. The controller has impedance control capability for the master and slave manipulators' positions. And it has also continuous path(CP) control capability for the slave manipulator's orientation. The impedance control allows the master and slave(More)
High-fidelity color imaging technology that incorporates spectrum-based color reproduction system, called "natural vision" (NV) is applied to the field experiment of telemedicine. The experiment comprises mainly two parts; 1) High-fidelity color video of open surgery was captured by the six-band multispectral camera, and the image quality was visually(More)
—In the present paper, we describe a method for constructing a remote ultrasound diagnostic system. Remote diagnosis can be realized using a communication network. We have developed a master–slave type remote medical system to diagnose shoulder diseases, such as dialysis-related amyloid arthropathy (DRAA), by ultrasonographic images. Proper positioning,(More)
A master-slave type remote ultrasound diagnostic system was developed. This paper presents and evaluates its control strategy. There is only one impedance controller that is located in the master site or the slave site or the relay point in the conventional impedance controller. Therefore, the effect of the time lag in transmitting force and position data(More)
