How do scanner crystals work
WebLike most, I live on my phone. My daily routine involves using several different apps to manage my lifestyle, provide professional support, and communicate within numerous networks. Recently, many scanner identification apps have appeared on the Apple App Store. They can identify plants, insects, trees, birds, dogs, cats, mushrooms, and more. WebA drawback of the collimator is that only less than 1 per mill of all photons can penetrate it. Thereby the sensitivity of the system is reduced. In contrast to a conventional gamma camera, PET scanners are multi-crystal cameras. Detection of radioactivity results from coincidental stimulation of two opposite crystals in the ring system.
