Slide:%Project.SceneNumber%.%Scene.SlideNumber% Continue Introduction to Photo-Counting Fundamentals Quantum Technology – Elimination of Electronic Noise Follow an expert and a student as they discuss electronic noise in EIDs and the advantages of photon-counting technology. Explore the subject interactively. Master Template HILS2218 | Effective Date: 25 Mar 2022 ? Start Disclaimer Introduction EID time [ns] pulse-height [keV] Film 1 Select 2 answers. Knowledge Check 1 of 2 How do X-ray signals with less than 20 keV contribute to a CT image? ? They provide relevant information for the CT image. There are practically no photons with an energy below 20 keV that reach the detector. The EID incorporates electronic noise in the measured signal, so the image quality is degraded. The EID identifies photons with an energy below 20 keV. Knowledge Check 1 Incorrect There are practically no photons with an energy below 20 keV that reach the detector. The ElD incorporates electronic noise in the measured signal, so the image quality is degraded. Continue Correct Continue time [ns] pulse-height [keV] PCD Threshold Signal Pulses Electronic Noise Film 2 EID vs. PCD Imaging Move the slider to see the difference between an image with and without electronic noise. Energy-Integrating Detector (EID) Photon-Counting Detector (PCD) Image courtesy of University Hospital of Tübingen, Tubingen, Germany ? EID vs. PCD Imaging Select the best answer. ? Because a PCD converts the electronic noise to a usable signal. Because a PCD can’t detect electronic noise. Knowledge Check 2 of 2 Why can a PCD eliminate electronic noise? Because a PCD uses a specific filter. Because a PCD can measure the energy of each individual photon. Knowledge Check 2 Incorrect A PCD can eliminate electronic noise, because it can measure the energy of each photon individually.
