What is the angling of the anode results in the effective focal spot being smaller than the actual focal spot? What is the imaginary geometric line that can be drawn based on the actual focal spotsize vs. What is the area of the target material being bombarded by electrons from the filament? The anode is angled toward the cathode, which allows the use of a larger focal spot is what principle? What is the area where the electron beam hits the anode? Why does the anode spin in the x-ray prior to taking it? What type of anode spins around when the foot pedal is stepped on? What type of anode is used in portable units and dental units? T/F Electrons from the cathode have a collision with the target on the anode and heat and x-rays are produced. How much is heat and how much are x-rays? When the electrons from the cathode hit the target on the anode the energy from the electrons changing directions is released and x-ray and heat is produced. What controls the amount of electrons released that is based on heat? What controls the acceleration of electrons? What is the amount of energy produced by? Source of electrons, way to accelrate electrons, path free of obtables for electrons to pass through, and a tube for vacuum environment What are 5 things that are required for x-ray production? What component of an x-ray tube are x-rays created? What component of an x-ray tube is a tungsten disc that acts as the target fir the electrons that come from the wire filament? What component of an x-ray tube is a wire filament (usually tungsten) that is the source of the electrons? What component of an x-ray tube is a vacuum that prevents accelerated electrons from colliding with air molecules? What can cause certain materials to fluoresce (give off light) which enables us to record an image? What can interact with matter, which causes biological alterations (ionization) at the molecular level? T/F X-rays have a longer wavelength than visible light. You can move items to the Trash from within the app, with a menu option giving the safeguard of undoing this action if you make a mistake.What is a form of electromagnetic radiation traveling through space as a combination of electric and magnetic fields? Decide how old the files you want to remove are, from one week to one month or one year.ĭisk Cleaner and Duplicates Finder allows you to restore all files in case you remove something accidentally. It can also be set to find all large files on your disk. This includes the obvious choices of the Trash and Downloads folder, as well as locations you may not otherwise think to purge or even know where to find such as application logs, web browser caches and cookies, application caches and an ever-growing list of email attachments stored locally but never cleaned. Disk Cleaner speeds up your computer and by finding and removing temporary files on your computer. All duplicate files are checked byte-by-byte to give you 100% guarantee they are exact copies.ģ. This scan can reveal just how many copies of the same document, photo or other type of file you have saved, scattered through your disk. Duplicate Files Detector frees up disk space by finding and deleting duplicate files and folders, giving you a chance to recover gigabytes of your disk space. At a glance you can identify which folders are the space hogs and just what is in them by successively drilling down.Ģ. Folder scanner is a visual disk/folder analyser that enables you to spot large files and folders on your disk - be it an entire hard disk or a subfolder, and provide a sorted breakdown of just where your disk space is being used.
