Abstract
A method and system for diagnosing an imaging system are provided. The method includes varying a system parameter of the imaging system. The method further includes obtaining a first data set at a first state of the varied system parameter and a second data set at a second state of the varied system parameter.
Claims19
A method for diagnosing an imaging system, said method comprising:
- obtaining a first data set by scanning an object at a first state of a system parameter of the imaging system;
- varying the system parameter from the first state to a second state at a sub-harmonic frequency;
- obtaining a second data set by scanning the object at the second state of the system parameter;
- and
- comparing the first data set and the second data set to diagnose the imaging system.

A method for diagnosing an imaging system, said method comprising:
- measuring a system response to a system parameter of the imaging system in a first state;
- changing the system parameter between the first state and a second state at a sub-harmonic frequency;
- measuring the system response to the system parameter in the second state;
- comparing the system response in the first state with the system response in the second state;
- and
- diagnosing the imaging system based on the comparing.
3 more elements
An imaging system comprising:
- an image acquisition portion for acquiring image data;
- a controller configured to control the image acquisition portion and to vary a system parameter of said imaging system, said controller further configured to:
- obtain a first data set by scanning an object at a first state of a system parameter of the imaging system;
- vary the system parameter from the first state to a second state that is different than the first state at a sub-harmonic frequency;
- obtain a second data set by scanning the object at the second state of the system parameter;
- compare the first data set and the second data set;
- and
- diagnose said imaging system based on the comparison.
