A new web-based patients' monitoring and diagnosis system in lab-view environment is developed, to acquire, store and process the data, by connecting the patient to a specialist for detecting, online, alert high-risk stages. Graphical User-friendly Interfaces (GUIs) are used to display, communicate and process Heart Rate (HR), and beat-to-beat rate (RR) intervals, from raw sensor data of ECG signal, pulse rate, body temperature. Transmission Communication Protocol (TCP)/User Datagram Protocol (UDP) is communication link between local and remote PCs. Two modes of operation, transferring stored data files on demand and sending data online for alert conditions are given. A case study of the system's performance and experimental verification for heart line data with varying heart rate and rhythm is presented.

Tissue phantoms are, generally, used in the calibration of therapeutic and diagnostic systems. Thus, Tissue-Mimicking (TM) phantoms are developed and studied here for various ultrasonic output parameters. These phantoms have been developed by using agar-based Tissue-Mimicking Materials (TMM) with alumina as an absorption material. A pulser ? receiver (make Panametrics, Model ? 5800, Waltham, MA 02154, USA) has been used to measure ultrasonic velocity and attenuation coefficient, which were found to be 1540?1550 m/s and attenuation 10.0?35.0 dB/m-MHz at frequencies from 2.5 MHz to 5.0 MHz. These ultrasound test phantoms incorporating TM material are useful in the performance evaluation of medical ultrasound systems.
