X ray production an overview
X-RAY PRODUCTIONAN OVERVIEW

  • VACUUM TUBE----WHY?

  • SOURCE OF ELECTRONS (TUNGSTON)WHY?

  • TARGET (TUNGSTON) WHY?

  • HIGH POTENTIAL DIFFERENCE(VOLTAGE) WHY?


Rad terms facts
RAD. TERMS/FACTS

  • ELECTRON CLOUD

  • SPACE CHARGE

  • 99% HEAT

  • 1% X-RAY

  • WAVELENGTHS

    • AMPLITUDE

    • FREQUENCY

      • SHORTER THE WAVELENGTH ,THE HIGHER THE FREQUENCY


Electromagnetic radiation
ELECTROMAGNETIC RADIATION

  • GAMMA

  • X-RAY

  • VISIBLE LIGHT

  • MICROWAVES

  • RADIO WAVES

  • COMPARE THE WAVELENGTH (SHORTER OR LONGER?) THE FREQUENCY (LONGER OR SHORTER) OF THESE ENERGIES TO X-RAYS


X ray vs visible light

TRAVEL IN STRAIGHT LINES

AFFECT PHOTOGRAPHIC EMULSIONS

CAN PRODUCE HARMFUL EFFECTS TO BODY

  • WHAT IS THE DIFFERENCE?


Ionization it s not as bad as it sounds
IONIZATIONIT’S NOT AS BAD AS IT SOUNDS!!!!



Sources of ionizing radiation bushong pgs 5 6

MAN-MADE gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

X-RAYS

NUCLEAR POWER /WASTE

NATURAL

COSMIC

RADIOACTIVE MATERIAL IN EARTH

POTASSIUM 40

SOURCES OF IONIZING RADIATION Bushong, pgs 5-6


The x ray beam

Small area of target gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

Cone shaped

Primary beam

Radiation field

Central ray

collimator

Scatter

Why is called that?

THE X-RAY BEAM


Return to scavenger hunt results and review
RETURN TO SCAVENGER HUNT RESULTS AND REVIEW gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • Add the following to your scavenger hunt notes

  • DISTANCE

    • SID AND OID

  • DENSITY

    • mA, mAs

  • CONTRAST

    • kVp


Units of measurement in radiography traditional si unit

ROENTGEN gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

Weighting factor
Weighting Factor gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • Useful for measuring occupational dose

  • Look at the table 1-3 on page 29…which of these ionizing radiation do you think would produce the most harm?

  • Why?


Brief overview of radiobiology
Brief overview of radiobiology gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • Laws of Bergonie and Tribondeau pg 30 in Ehrlich

    • Age

    • Differentiation

    • Metabolic rate

    • Mitotic rate

  • Effects

    • Short term/Long term somatic

    • Genetic


Keeping safe
KEEPING SAFE gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • We just discussed a method of recording radiation…how do we keep this exposure to its lowest level

  • QUIT THE PROGRAM??????

  • No…there are better ways!!!!!


Measuring radiation for the radiographer
MEASURING RADIATION FOR THE RADIOGRAPHER gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • FILM BADGE

  • TLD

  • OSL

  • CONTROL

  • 5 rem per year

  • 1 rem x age is cumulative dose limit


Cardinal principles of protection
Cardinal principles of protection gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • TIME

  • DISTANCE

  • SHIELDING

  • DESCRIBE HOW THESE APPLY TO BOTH PATIENT AND OCCUPATIONAL WORKER?

  • PRIMARY BEAM AND CR


Alara
ALARA gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • AS

  • LOW

  • AS

  • REASONABLY

  • ACHIEVABLE


Patient protection
PATIENT PROTECTION gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • ERRORS

  • REPEATS

  • COLLIMATION

  • HIGHEST KVP. WHY?

  • FAST SCREEN/FILM

  • AT LEAST 40” SID


Patients are frightened about radiation
Patients are frightened about radiation gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • What can we say or do to educate them?


Occupational protection
OCCUPATIONAL PROTECTION gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • YOU TELL ME!

  • .5MM LEAD SHOULD ATTENUATE 90% OF RADIATION AT 75 kVp

  • Thyroid shields


Rose aehle rt r m

ROSE AEHLE RT (R,M) gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

Appendix A


What do radiographer s do

WHAT DO RADIOGRAPHER’S DO? gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

WHAT IS OUR SCOPE OF PRACTICE?


Chapter 12 ehrlich
CHAPTER 12, EHRLICH gains an electron. When the loss or gain occurs, a net charge is produced. Ionization can disrupt matter.

  • In addition to radiographers being trained in the OR, in trauma radiography and in mobile radiography they can cross train in
