If you're aiming for a genuinely one-operator portable system, the equipment that truly fits the requirement are handheld or cart-based ultrasound and lightweight DR X-ray systems. Modern handheld ultrasound units can be the size of a phone or tablet, typically weigh just a couple of pounds, and sync with mobile devices including phones and tablets.
For setups intended to be handled entirely by one individual, the only practical choices are ultrasound scanners in handheld or small cart form and carry-ready digital X-ray setups. Contemporary compact ultrasound scanners can be built as handheld probes or tablet systems, typically weigh just a couple of pounds, and sync with mobile devices including phones and tablets.
If you want an imaging solution that one person can deploy alone, the most achievable solutions are mini ultrasound devices and compact DR X-ray equipment. Today’s portable ultrasound devices can be built as handheld probes or tablet systems, are incredibly lightweight, and connect to a laptop, tablet, or even a phone.
