The x ray beam contains - Study guides, Class notes & Summaries

Rectification Constant - A value of the heat unit formula that varies depending on the generator used. Generators used in Radiography - single phase generator delivers pulsating x-ray beam (1), Three phase generator = 3 phase 6 pulse machine (1.35) , High frequency generator = 3 phase 12 pulse machine (1.41) Rectification - The rectifier of the x-ray tube changes alternating current (AC) to direct current (DC). This process ensures that the x-ray production flows in the right direction; fr...

2024/2025 HESI Radiography Practice Test 1 - Questions, Answers and Rationales (Complete Solutions) How is signal maximized to a digital image receptor? a. Lower milliamperage (mA) setting. b. Shorter exposure time. c. Higher source to image receptor distance (SID) value. d. Longer exposure time. The greatest signal strength is obtained with longer exposure time. The other responses reduce signal at the digital image receptor. Which is the best approach for speaking to a patient with a hearing...

Periodontal disease - Infection of the structures that support the teeth (gums and bones) Mercury, silver & tin - What is amalgam fillings composed of Periodontal disease - Bone loss in the jaw is an indication of what disease Concept of radiation that states that exposure should be kept "as low as resonably possible" - What is the ALARA concept Positive - Anode Negative-Cathode - What is the positive & negavtove electrode in the x-ray tube Film, phosphorous stor...

X-RAY TUBE correct answer: -Electronic vacuum tube that contains two electrodes: the cathode and anode (a diode), which are necessary for the production of x-ray beam -the most important part of the x-ray, at the same time it is also the most vulnerable. cathode and anode correct answer: two electrodes Coolidge (Cathode ray) tube correct answer: - the first x-ray tube used 30 to 50 cm long and 20 cm in diameter correct answer: Modern x-ray tube measures around glass correct answ...

Which is not a parenteral route of administration? A. IM B. IV C. SQ D. Oral - Oral Which of the following is not a valid reason for cleaning x-ray cassettes on a regular basis? A. To prevent the spread of disease from animal to animal B. To prevent debris from interfering with the image once developed C. To preserve the life of the cassette D. To decrease residual radiation hazard - To decrease residual radiation hazard The Rabies vaccination must be given to puppies by wha...

The main advantages of CT over conventional radiography are -Elimination of superimposed structures - the ability to differentiate small differences in density of an atomic structures - superior quality of the images Computer tomography for technologists exam review Romans chapter 1 page 3 CT image quality is evaluated using a number of criteria including - spatial resolution - low contrast resolution - temporal resolution Computer tomography for technologists exam review Romans...

How many alterations in the direction of the current flow occur in 0.10 seconds in a 60 Hz AC current Correct Answer 12 (60Hz= 120 pulse/sec; .10 x 120 = 12) The _______ is the source of radiation in the x-ray tube Correct Answer Actual focal spot High frequency generators Correct Answer 1) use inventors to increase pulse frequency 2) produce similar outputs to three-phase with a single phase source 3) achieve peak kvp faster than single or three-phase generators Where is the stator o...
