A mobility apparatus for an imaging appliance such as a panoramic radiograph machine allows single-operator transport for on-site usage with ambulatory challenged patients. A counterbalanced pivot interface integrates the imaging appliance with a motorized transport vehicle for disposing the appliance securely on the vehicle, while the counterbalanced pivot interface allows positioning to an operational upright orientation for on-site usage. The imaging appliance includes modifications to a stock appliance for adapting the pivot interface for mobility and for usage with ADA (Americans with Disabilities Act) affected patients, such as wheelchair and scooter bound individuals. The modifications include a truncated base and truncated vertical riser, coupled with a counterbalance mass on the vehicle to maintain stability in the deployed and transportable positions. The lowered vertical riser permits the imaging mechanism to descend to accommodate seated patients.
