Abstract
The invention generally relates to methods for manually calibrating imaging systems such as optical coherence tomography systems. In certain aspects, an imaging system displays an image showing a target and a reference item. A user looks at the image and indicates a point within the image near the reference item. A processer detects an actual location of the reference item within an area around the indicated point. The processer can use an expected location of the reference item with the detected actual location to calculate a calibration value and provide a calibrated image. In this way, a user can identify the actual location of the reference point and a processing algorithm can give precision to the actual location.
Claims20
A method of calibrating an imaging system, the method comprising:
- displaying an image showing a target and a reference item;
- receiving user input indicating a point within the image;
- detecting a location of the reference item within an area around the indicated point;
- calculating a calibration value based on the detected location of the reference item;
- and
- providing a calibrated image of the target at a known scale.
An imaging system comprising:
- a processor and a computer-readable storage medium having instructions therein which can be executed to cause the system to:
- display an image showing a target and a reference item;
- receive user input indicating a point within the image;
- detect a location of the reference item within an area around the indicated point;
- calculate a calibration value based on the detected location of the reference item;
- and
- provide a calibrated image of the target at a known scale.
