The instant transmission of radiological images may be important for making rapid clinical decisions about emergency patients. We have examined an instant image transfer system based on a personal digital assistant (PDA) phone with a built-in camera. Images displayed on a picture archiving and communication systems (PACS) monitor can be captured by the(More)
A mobile telemedicine system, capable of transmitting video and audio simultaneously, was designed for consulting acute stroke patients remotely. It could use a wireless local area network (e.g. inside the hospital) or a mobile phone network (e.g. outside the hospital). When initiating a call, the sending unit chose a suitable encoding profile based on the(More)
In this paper, we considered a planar perspective transformation between images with overlapping region. It is based on the rectangle-to-quadrilateral mapping and normalized correlations. Initially, the global translation is determined by using a block matching. And to find the correspondence points maximizing correlation in overlapping region by the(More)
We tested three imaging devices for suitability in emergency dental situations for telemedicine. The three devices were a special-purpose oral camera, a digital single lens reflex (DSLR) camera, and the built-in camera of a mobile phone. A total of 20 subjects volunteered to take part in the study. We simulated five different conditions which could affect(More)
Video-encoders in telemedicine systems need to adjust their coding methods for operation on heterogeneous networks on which bandwidth fluctuates. We evaluated MPEG-4 compressed video-pictures of three trauma patients. We compared the original video-frames with compressed video-frames in terms of the peak signal-to-noise ratio (PSNR). In a qualitative(More)
Myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) is a multisystem clinical syndrome manifested by mitochondrial myopathy, encephalopathy, lactic acidosis and recurrent stroke-like episodes. A 27-year-old female with MELAS syndrome presented with cerebral infarction. Echocardiography revealed a thrombus attached to the apex of the(More)
Two different prototype mobile telemedicine systems were constructed for use in the emergency room. They could transmit physiological signals as well as video pictures and sound. One device, the mobile emergency bed (MEB), was powered by battery and had a wireless connection to the local-area network (LAN). For the other, the mobile emergency server (MES),(More)
In this article, on page 204, the title has been spelled incorrectly: " MEALS " should have appeared as " MELAS ". The title should be corrected as the following: from " A Case of Myopathy, Encephalopathy, Lactic Acidosis and Stroke-like Epicodes (MEALS) Syndrome with Intracardiac Thrombus " to " A Case of Myopathy, Encephalopathy, Lactic Acidosis and(More)
