Abstract
An imaging system that includes a radiation source. An image receptor is located to receive radiation emitted by the radiation source. The imaging system further has a servo system that includes a computer operationally coupled to a motor-load element. The servo system is configured to position the radiation source, the image receptor and the object to be scanned. The servo system is configured to measure at set time intervals in real-time a position of the radiation source, the image receptor, and the object. The measured position is used to predict a native hardware motion parameter value for the servo system.
Claims20
An imaging system comprising:
- a radiation source;
- an image receptor located to receive radiation emitted by said radiation source;
- and
- a servo system comprising a computer operationally coupled to a motor-load element, said servo system configured to position at least one of said radiation source, said image receptor, and an object to be scanned, wherein said servo system is configured to measure at set time intervals in real-time a position of at least one of said radiation source, said image receptor, and said object, wherein said measured position is used to calculate a native hardware motion parameter value for said servo system.
A method of improving collision detection between an object and an electromechanical system having a mechanical output controlled by a servo system, said method comprising:
- (a) determining servo system motor-load element parameter values in real-time;
- (b) calculating in a native motor-load model a motion control parameter value for a motor-load element of said servo system using at least one of said real-time servo system motor-load element parameter values;
- and
- (c) applying said calculated motion control parameter value in an operation within a computer element of said servo system to enhance a control signal output from said computer element to said motor-load element of said servo system.
A computer-readable medium having a set of instructions for execution on a computer, said set of instructions comprising:
- a monitoring routine for determining a servo system motor-load element parameter value in real-time;
- a calculation routine for applying said real-time servo system motor-load parameter value into a native motor-load model to calculate a motion control parameter value;
- and
- a control signal routine that applies said calculated motion control parameter value to an operation that modifies a control signal output of a computer element of a servo system.
