  1. It’s been a long road…….. When will it end?

  2. Hang in there You are almost there!

  3. GESTATION IN HUMANS: THREE STAGES Let’s clarify some points 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 FROM CHAPTER 8…STILL

  4. CHAPTER TEN What is noted on this power point is what will be covered on the next exam

  5. OBJECTIVES TO BE COVERED IN CHAPTER TEN • Distance from the patient’s skin from the collimator (pg 209) • Measuring units of luminance and recommended level of luminance pg 209-210 • Radiographic and light beam correspondence with SID pg 211

  6. OBJECTIVES TO BE COVERED IN CHAPTER TEN • Minimal source to skin distance for mobile radiography, c-arms, fluoroscopy (pgs 222 , 231) • Review of patient exposure with image intensification and multifield imaging (pgs 229) • Intermttent or pulsed fluoroscopy (230) • Total filtration and HVL for an imaging intensifying system pg 231

  7. OBJECTIVES TO BE COVERED IN CHAPTER TEN • ESE for general purpose fluoro pg 232 • ESE for HLC (pg 232) • Lead equivalent requirement for primary protective barrier (pg 198) • Cinefluorography. What is it?pg 232-235 • 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?

  8. OBJECTIVES TO BE COVERED IN CHAPTER TEN • Compare the structural difference between an analog fluoroscopy system and a digital system. Pg 235 • Describe pulsed progressive systems. pg 235 • Discuss why HLCF is preferred for certain examinations. Pg 235 • What nonstochastic skin injuries may be detected after an interventional study. What Rad level may cause this? Pg. 236
