Strange to hear the current ultrasound machines being described as 'clunky' - the one at my (NHS) hospital where my wife got her scans was pretty awesome. The level of ergonomic & functional design that went into it was fantastic, and the operator knew exactly what she was doing. The machine had clearly been designed in collaboration with the end user, as it had e.g. cubby holes for gel bottles and all smooth easy-to-clean surfaces. The nurse had one hand on the scanner, and the other on a trackball with which she was marking up the images as she took them - the images zipped to the side of the screen in a nice thumbnail list as she took them, and everything worked really well.
Considering how often bespoke technology workplace seems to be poorly thought out or just generic stuff pressed into service, I was very impressed.
