A remote ultrasound assessment and intervention system comprises a console having a controller for an ultrasound imaging device attachable to a human skin surface or implantable in a human body cavity. Commands from a remote work station located, for example, at a hospital may remotely control a transducer of the device to move in x, y, z, rotate and tilt directions to remotely assess an injury to a victim, for example, of a war zone injury or terrorist attack. A first responder, who need not be medically trained, may be instructed via a communications link or via a predetermined controller program stored in computer memory to move the imaging device from one location to another on the human skin surface or in a human body cavity. Intervention is also remotely controlled, once an injury is assessed and diagnosed from the hospital work station via an image guided catheter manipulated by the first responder via commands received from the hospital work station.
