Flatbed scanners let you scan an array of documents including photographs, loose documents and pages within a book as well as any item that can lay flat on the scanner's surface. The devices interface with Windows, Mac and Linux systems and come with user-friendly application programs.uring the scanning process, documents lay flat on the device's glass platform and do not have to move through a series of feed rollers like drum scanners. This reduces the risk of the documents being damaged or getting caught by the rollers inside of handheld or drum scanners.
PET scans also use radiopharmaceuticals to create three-dimensional images. The main difference between SPECT and PET scans is the type of radiotracers used. While SPECT scans measure gamma rays, the decay of the radiotracers used with PET scans produce small particles called positrons. A positron is a particle with roughly the same mass as an electron but oppositely charged.
