Image display calibration for ultrasound and other systems
First Claim
Patent Images
1. An ultrasound system for calibration of an ultrasound imaging display, the system comprising:
- a flat panel display having a front side for viewing ultrasound images;
a cover, the cover and flat panel display positionable in an open position for use and a closed position wherein the front side is adjacent the cover;
a light sensor positioned in or on the cover; and
a processor operable to calibrate a characteristic of the flat panel display as a function of a signal from the light sensor;
whereby ultrasound images displayed on the flat panel display are more likely to have a similar display characteristic over time in response to the calibration.

Abstract
A light sensor is positioned to detect and correct for variations in light output by a flat panel display over time. The calibration occurs automatically, rather than in response to user activation of a calibration routine. The light sensor is positioned fixedly and senses in front of the flat panel display. The light sensor is used on a medical diagnostic or other imaging system.

10. A system for calibration of an imaging display, the system comprising:
-
a flat panel display;
a light sensor separate from the flat panel display; and
a processor operable to calibrate a characteristic of the flat panel display as a function of a signal from the light sensor, the processor operable to calibrate automatically free of user initiation of a calibration routine. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method for calibrating an imaging display, the method comprising:
-
providing a light sensor fixed in or on a cover;
allowing positioning of the light sensor adjacent to a front of a flat panel display;
sensing color, brightness or combinations thereof of the flat panel display with the light sensor; and
calibrating the flat panel display as a function of the sensed color, brightness or combinations thereof. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
