Exposure Data Recognizer (EDR)

Automatically optimizes the density and contrast of X-ray images.

The software automatically adjusts the density and contrast of an X-ray image to obtain the best results even under slightly different exposure conditions.

Processing flow

After the EDR function creates an image for recognition, it recognizes the partitioned patterns of an image, finds the exposure field, determines the necessary area for diagnosis, and adjusts the density and contrast based on the image histogram.

Histogram analysis (chest example)

From the recognized image, the EDR creates a histogram of the image that shows the size and frequency of the signal of each pixel corresponding to the exposed X-ray amount.

The function recognizes the range of the mediastinum (red) from the high-density area (blue) of the lung field and adjusts the image density.
