background: nowadays medical equipment plays an important role in the treatment and in the medical education. using outdated preventive maintenance (pm) system may cause problems in the cutting edge medical equipment, nervous system disease’s equipment (in diagnosis and treatment) which are crucial for every medical center. based on above facts we focused on nervous system treat units’ equipmen...

Ultrasonic imaging and tissue characterization is a noninvasive technique widely used in medicine for many years to assess body conditions. However, the expertise required to operate the equipment and interpret the results is not always available. The medical ultrasonography project is developing a system concept for a remotely steerable, multibeam ultrasonic scanner that can be operated by ski...

Phased array ultrasonic testing technology is of flexible, reliable, efficient and suitable for special equipment welds non-destructive testing. Sectorial scan angle range was investigated in this paper for phased array ultrasonic oblique incident pulse shear wave testing of special equipment welds made in low carbon steel. The theoretical calculation of ultrasound wave energy transmission coef...

Refrigeration service personnel have used leak detection equipment for years when servicing refrigeration equipment. In the past, leak detection typically was only concerned with leak pinpointing, either with an ultrasonic device, soap bubbles, dyes, thermal conductivity, or other electronic devices. Today, refrigerant leak detectors exist not only for pinpointing leaks, but also for monitoring...

Ultrasonic technology is in several ways ideally suited to cardiac research and to routine clinical examinations. It provides truly real time images and detailed information on moving anatomical structures and blood. The portable nature and relatively low cost of the equipment makes it well suited to use in hospitals. Ultrasonic technology for cardiology is still developing and in recent years ...
