The beam-hardening effect emanates from favorable integrations of low-energy multicolored electromagnetic waves, and X-ray beams that infiltrate an object. Likewise, thicker objects have streaks on its outer part (also known as streaking artifacts) which form some of the effects of beam hardening. Therefore, the quantity of photons striking an X-ray detector is not entirely proportionally related to the permeated material density.Ĭonversely, many re-established methods speculate that linear depletion causes the external part to have a different color from its internal structure (also known as the cupping artifacts). Since the X-ray depletion depends solely on energy, when the beam permeates the object of inspection, little energy X-rays are sharply depleted than high energy X-rays. Multicolored spectrum x-ray beams are what most industrial x-ray sources generate. With better image quality, accurate assessment becomes a possibility. Therefore, the mean beam energy is heightened, a concept also known as beam hardening.įurthermore, Beam Hardening is a type of feature where the X-ray spectrum shifts to higher powerful energy which is a result of the withdrawal of a lower x-ray electromagnetic wave.īeam hardening is crucial when it comes to obtaining useful data about the internal structure of an object under assessment because accurate data is to be obtained from material inspection and analysis.Īnother noteworthy importance is that Beam hardening increases the possibility of acquiring a better quality image as a result of the increase in the photons application on the object of interest. The outcome is theoretically related to a high-pass filter, that is, only higher energy photons are left to supply the beam. ![]() So, if you want to know what causes it and how to reduce it then let’s dive in together.īeam hardening is a type of physics-based artifact that emanates from manual procedures demanded in obtaining information about the internal structure of a test sample or material.īeam hardening is the situation that occurs when an X-ray beam composed of a range of energies permeates an object and ends with specific weakening lower energy photons. Consequently, the artifact produced in this situation is known as beam hardening and is the focus of this post. This challenge is often caused by an assumption that X-ray beam attenuation is linear rather than being treated as a spectrum range of energies. One of these challenges involves the reconstruction of an X-ray image where the edge looks brighter than other parts of the image despite the material being homogenous. ![]() What comes to mind when you hear of beam hardening?Ĭhallenges often occur during X-ray inspection processes that hinder the correct representation of the test samples for an accurate result.
