If specialized procedures are used with a child such as lateral fluoroscopic x-ray or use of a nasoendoscope, s/he is being evaluated for whether or not_________is normal.
Homework Answers
If specialized procedures are used with a child such as lateral fluoroscopic x-ray or use of a nasoendoscope, s/he is being evaluated for whether or not the nose or nasal cavity is normalis normal.
By using lateral fluroscopic x-ray it is possible to see the realtime images of the cavity of the nose & can be used to find out problems related to the nasal cavity as well as other regions. It is posible to find problem related to nasal congestion, sinusitis etc..
nasoendoscopy is a procedure to visualize the interior of nasal cavity again to find out resons for nasal congestion, sinusitis etc...

6 You are presented the following X-ray from a six-year-old child (Fig. 8.42). a identify the bones in the X-ray. b Your colleague thinks that there may be a fracture present at the arrow in Figure 8.42. What do you think? Is this a fracture or a normal anatomical feature? Explain. (Hint: Think about bone development in children. What structure is present in many bones at the epiphysis?)

The lifespan of an X-ray tube used as part of an X-ray imaging machine follows a normal distribution with a mean of 7 years and a standard deviation of 1.65 years. Standard Normal Distribution Table a. Calculate the probability that a randomly-selected X-ray tube will have a lifespan of: (i) Less than 4 years P(X< 4) = 0 (ii) Greater than 9 years P(X > 9) = 0 (iii) Between 5 and 8 years P(5< X < 8) = 0...

31. Provide examples where projection and positioning during routine x-ray procedures can be used to reduce patient exposure and provide radiation protection in a procedure involving exposure to ionizing radiation. 32. Describe briefly the differences in designating an area as a “Radiation Area”, “High Radiation Area” and a “Very High Radiation Area” with respect the potential risk from exposures to ionizing radiation. 33. Provide at least two examples where excellent projection and positioning in X-ray imaging can be used effectively...

Problem 2. X-rays a) Maybe the most common characterization method that uses X-rays, is X-ray Absorption Imaging. This is basically the same technique as used in hospitals and dentistry. i. What is the sample/ material parameter that makes contrast (dark/ bright image features) in an X-ray absorption image? ii. Explain what is meant by (2D) X-ray Absorption Imaging being a “shadow image”. iii. What limits the resolution in an X-ray Absorption Image? b) Most X-ray based spectroscopy techniques have an...
