Aluminum disk xray filtration6/17/2023 the purpose of this is to supply the electrons necessary to generate x-rays The _ or _ electrode, consists of a tungsten filament in a focusing cup made of molybdenum. The x-ray tube is the _ of the x-ray generating system. Open ended lead lined cylinder that extends from the opening of the metal housing When the size and shape of the beam are changed to a rectangle only slightly larger than the film the amount of tissue exposed to radiation can be Metal disk with a small opening in the center it is located inside the PID in the path of the x-ray beam, it limits the size of the x-ray beam Made of leaded class or aluminum keeps the oil in the tubehead and acts as a filter to the x-ray beamĪlters the voltage of incoming electric current Xray tube, metal housing, anode, insulating oil, unleaded glass window of xray tube, lead collimator,PID, aluminum discs, tubehead seal, filament circut, cathodeįills the housing and surrounds the x-ray tube, this prevents overheating by absorbign the heat created by the production of x-rays Tubehead, extension arm and control panel What are the 3 primary components that x-ray machines all have Which wavelengths are especially usefull in dentistry The _ the wavelength of the x-ray the _ is its energy Through space at the speed of light in a straight line with a wavelike motion Visible light, radar, radio, and television wavesĮlectromagnetic radiation is made up of photons that travel What things are also classified as electromagnetic radiation Tiny negatively charged particles that have very little massĮlectrons remain stable in their orbit around the necleus until Patients _ give off x-rays after the x-ray machine stops producing x-rays Edmund Kells dedication to the development of dental radiography eventually cost him hisįingers, later his hand, then his arm and after enduring much pain and being faced with the prospect of becoming a burden to his family he committed suicide in 1928.ĭense core of the atom that is compromised of particles known as protons and neutrons.ĭental x-rays _ make atoms radioactive Who is credited with the first practical use of radiographs in dentistryĬ. How long did the first dental radiograph take to expose Roentgen rays and roentgenology, and roentgenographs What were x-rays first referred to as, and what was radiology referred to as, and what were radiographs known as What represented the first radiograph of the human body _ has teh ability to cause damage to all types of living tissuesĪny exposure to radiation no matter how small has the potential toĬause harmful biologic changs in the operator and the patient Only through the use of dental radiographs Many dental diseases and conditions have no clinical signs or sympstoms and are typically discovered 38 ch review whole chapter for test reveiw QuestionĬonditions that are not visible in the oral cavity and to identify many conditions that might otherwise remain undetected
