It’s been a long road…….. When will it end?
Hang in there You are almost there!
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
CHAPTER TEN What is noted on this power point is what will be covered on the next exam
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
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
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?
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
