Its been a long road''

1
Its been a long road..

• When will it end?

2
Hang in there

• You are almost there!

3
FROM CHAPTER 6STILL

• GESTATION IN HUMANS THREE STAGES
• Preimplantation 0-9 days
• Organogenesis 10 days to 6 weeks
• Fetal
• 6 weeks to term

• 5-15 rad embryo death
• Radiation induced congenital abnormalities
• High levels fetal death

4
Lets compare those stats to this

• Chapter 8, pg 216
• 10 day rule now obsolete but
• Read box 8-11 NCRP 102
• In addition, damage to newborn unlikely under 20
  rad so NCRP considers the risk negligible at 5
  rad or less. Box 8-12

5
MORE CHAPTER EIGHT

• What is noted on this power point is what will be
  covered on the next exam

6
OBJECTIVES TO BE COVERED IN CHAPTER EIGHT

• Minimizing skin exposure from the collimater (pg
  172)
• Measuring units of luminance and recommended
  level of luminance pg 172
• Radiographic and light beam correspondence with
  SID pg 172

7
OBJECTIVES TO BE COVERED IN CHAPTER EIGHT

• Air gap technique pg 188
• Minimal source to skin distance for mobile
  radiography, c-arms, fluoroscopy (pgs 190,197 )
• Review of patient exposure with image
  intensification and multifield imaging (pgs 196)
• Intermittent or pulsed fluoroscopy (196)
• Total filtration and HVL for an imaging
  intensifying system pg 197

8
OBJECTIVES TO BE COVERED IN CHAPTER EIGHT

• ESE for general purpose fluoro pg 198
• ESE for HLC (pg 198)
• Lead equivalent requirement for primary
  protective barrier (pg 198)
• Cinefluorography. What is it?pg 200-201
• Exposure per frame
• What happens when the viewing mode is decreased??
• What happens when the frames per second
  increases?
• How much does the exposure factor change if the
  viewing mode is decreased or frames per second
  increases?

9
OBJECTIVES TO BE COVERED IN CHAPTER EIGHT

• Compare the structural difference between an
  analog fluoroscopy system and a digital system.
  Pg 201
• Describe pulsed progressive systems. pg 201
• Discuss why HLCF is preferred for certain
  examinations. Pg 202
• What nonstochastic skin injuries may be detected
  after an interventional study. What Rad level may
  cause this? Pg. 202

10
OBJECTIVES TO BE COVERED IN CHAPTER SEVEN

• Mammography pg 211 questions
• The average glandular dose from a routine
  mammogram is______?
• A 4.5cm compressed breast (film screen) should
  not exceed____per view

11
CHAPTER EIGHT CT questions pgs 212-214

• Is the ESE after a series of CT scans greater
  than the ESE for a single x-ray exposure?
• Compare CT scans to a more complex examination in
  terms of ESE
• What reduces exposure to patients in CT? Do you
  need direct shielding in CT
• Explain that when the spiral scan pitch ratio
  increases, the exposure is reduced as compared to
  conventional CT

THE END OF ROAD IS NEAR

• KIDS

PEDIATRICS ADDRESS THE FOLLOWING

• Leukemia and low dose
• Motion artifact
• Shielding
• Collimation
• CT technical exposures
