1 Introduction

Patients in a hospital intensive-care unit require constant monitoring with equipment that must have continuous power. Any loss of patient data is completely unacceptable in critical medical applications; plus, a power failure is likely to damage expensive electrical components in scanning equipment.

Medical ultrasound imaging is a diagnostic technique that enables the visualization of a person’s internal organs, including their size, structure and an estimate of their blood flow. Ultrasound scanners are available in premium, cart-based, portable and smart-probe versions, depending on the number of transmit and receive channels. Premium and cart-based ultrasound scanners are typically line-powered; however, they have multiple battery-packs to support backup power.
