Abstract
A non-transitory computer readable medium (26) stores instructions executable by at least one electronic processor (20) to perform a method (100) of monitoring an X-ray imaging device (1). The method includes retrieving air calibration data (32) generated by at least one air calibration performed for the X-ray imaging device; deriving a diagnostic metric indicative of a problem with or status of the X-ray imaging device from the retrieved air calibration data; and outputting an alert or status indicator (30) indicative of the problem with or status of the X-ray imaging device based on the derived diagnostic metric.
Claims20
A non-transitory computer readable medium storing instructions executable by at least one electronic processor to perform a method of monitoring an X-ray imaging device the method comprising:
- retrieving air calibration data generated by at least one air calibration performed for the X-ray imaging device;
- deriving a diagnostic metric indicative of a problem with or status of the X-ray imaging device from the retrieved air calibration data;
- and
- outputting an alert or status indicator indicative of the problem with or status of the X-ray imaging device based on the derived diagnostic metric.
An X-ray imaging system, comprising:
- an X-ray imaging device
- a controller configured to:
- control the X-ray imaging device to acquire an air calibration;
- determine gain normalization factors for X-ray detectors of the X-ray imaging device using the air calibration;
- control the X-ray imaging device to acquire an image of an associated subject using the determined gain normalization factors;
- and
- store air calibration data generated by at least one air calibration;
- and
- an electronic processor programmed to:
- retrieve the stored air calibration data;
- derive a diagnostic metric indicative of a problem with or status of the X-ray imaging device from the retrieved air calibration data;
- and
- output an alert indicative of the problem with or status of the X-ray imaging device based on the derived diagnostic metric.
