System and method to automatically assist mobile image acquisition
First Claim
1. A method of mobile image acquisition of a subject, the method comprising the steps of:
- providing an imaging system supported on a mobile device so as to steer movement of the imaging system across a floor;
releasing restraint of movement of the mobile device;
instructing movement of the mobile device in support of the imaging system to a first position for image acquisition of the subject;
receiving feedback that the mobile device is located at the first position; and
applying a brake force to restrain movement of the mobile device, wherein the step of applying the brake force includes creating a vacuum in restraint of movement of the mobile device relative to the floor;
wherein the step of applying the brake force further includes communicating electrical power to a vacuum pump so as to generate the vacuum between a vacuum clamp attached at the mobile device and the floor in restraint of movement of the mobile device with respect to the floor;
wherein a tank and a valve are located between communication of the vacuum pump to the vacuum clamp, the method further including the step of moving a position of the valve to a first valve position to communicate the vacuum from the tank to the vacuum clamp; and
wherein upon release of the vacuum by the valve to atmosphere, a spring bias moves the vacuum clamp away from the floor.

Abstract
A system and method to perform image acquisition of a subject is provided. The system includes a mobile device to move an imaging system across a floor, and a brake system that restrains movement of the mobile device. A controller includes a memory having program instructions to instruct a processor to perform the steps of: instructing movement of the mobile device in support of the imaging system to a first position for image acquisition of the subject; receiving feedback that the mobile device is located at the first position; and applying a brake force to restrain movement of the mobile device. The step of applying the brake force includes generating a vacuum in restraint of movement of the mobile device with respect to the floor.

6. A system to perform image acquisition of a subject, comprising:
-
an imaging system; a mobile device operable to move the imaging system across a floor; a brake system that restrains movement of the mobile device with respect to the floor; a controller in communication with the imaging system, the mobile device, and the brake system, the controller including a memory having a plurality of program instructions to instruct a processor to perform the steps of; instructing movement of the mobile device in support of the imaging system to a first position for image acquisition of the subject; receiving feedback that the mobile device is located at the first position; and applying a brake force to restrain movement of the mobile device, wherein the step of applying the brake force includes creating a vacuum between a vacuum clamp of the mobile device and the floor in restraint of movement of the mobile device relative to the floor; and a spring, wherein the system is configured such that, in operation and upon release of the vacuum by a valve of the brake system to atmosphere, a spring bias provided via the spring moves the vacuum clamp away from the floor. - View Dependent Claims (7, 8, 9, 10, 11, 12)
