The communication and information technology is creating a variation of change and transform in the entire education system. One of the powerful manifestations of this communication and information technology is the use of computer in training. Computer has much potential in education of exceptional students, especially, for students with visual impairment. By applying the computer and suppleme...
In this work a distributed video surveillance system based on a Client-Server architecture is presented. The proposed system is accessible from portable devices such as tablets, smartphones, etc. In a typical real-world scenario, for example in homeland security, it is useful to have portable devices that can receive in real-time a frame or a sequence of frames coming from a selected camera to ...
Scintillation gamma cameras based on low-noise electron multiplication (EM-)CCDs can reach high spatial resolutions. For further improvement of these gamma cameras, more insight is needed into how various parameters that characterize these devices influence their performance. Here, we use the Cramer-Rao lower bound (CRLB) to investigate the sensitivity of the energy and spatial resolution of an...
Introduction:SURGEOSIGHT is a dedicated intra-operative hand-held gamma camera designed and manufactured by our team to be used for lymphoscintigraphy. Although conventional gamma cameras are widely used, they lack the capability of the sentinel lymph node (SLN) imaging in the operation room. Like conventional gamma cameras it is necessary to calibrate SURGEOSIGHT for linearity...
