Rather than relying solely on algorithmic image processing, Dual Energy Subtraction acquires two exposures at different energy levels in less than 160 milliseconds. You can process and view the image as:
These images help you detect abnormalities that may have been obscured in a conventional radiograph.
Dual Energy Subtraction is delivered within the Helix™ advanced image processing chain, delivering improved consistency despite variations in exposure technique and challenging exam conditions.
“The advent of routine Dual Energy Subtraction use has led to a reduction in our false positive findings when reporting indeterminate single energy chest radiographs.”
