Product Description<br />
The absorbed dose necessary to obtain a medical X-ray image with sufficient signal-to-noise ratio<br />
varies with object <strong>com</strong>position, thickness, and X-ray energy spectrum.<br />
The positive effects of energy filtering to optimize the spectrum were observed already at the<br />
advent of medical X-ray imaging.<br />
It was noted that putting a thin layer of material, such as a piece of silicon cupper, the X-ray<br />
medical image will be drastically improved.<br />
Absorption filtering is still the dominant method to filter out low-energy photons, often in<br />
<strong>com</strong>bination with a limited X-ray tube acceleration voltage to cut off photons of higher energy.<br />
with filter<br />
without filter<br />
