Section 1: Image Production

1. Study Resources

  • Read Mosby Chapter 4 - Image Production

    • Save practice questions for review

  • Radiographic Image Production section in RTBC

2. X-ray Tube and Components Module

  • Questions to Answer:

    • Draw the X-ray tube.

    • Identify positive and negative sides.

    • Explain the role of the glass envelope.

    • Explain the tube housing's role.

    • Identify the end of the tube with the filament and focusing cup.

    • Explain types of anodes and their materials:

    • Material Benefits: E.g. Tungsten has high melting point; good for heat dissipation.

    • Describe the induction motor, including:

    • Stator: Stationary part inducing magnetic field.

    • Rotor: Rotates to produce X-rays.

    • Bearings: Support the rotor.

  • Additional Resources:

    • MP YouTube video on Rad Safety 1 - X-ray production

  • Anode Heel Effect:

    • Define the anode heel effect.

    • Explain beam intensity on the cathode end. It is more intense due to:

    • The angle of the anode.

    • Explain the impact of decreasing the anode angle on the anode heel effect.

  • Line Focus Principle:

    • Define the line focus principle:

    • Compare actual focal spot vs. effective focal spot.

    • Discuss their locations.

    • Explain effects of decreasing surface area and angling.

  • Off Focus Radiation: Know basic definition.

  • Tube Loading (Heat Units):

    • Know the definition and formula:

    • Formula: extHeatUnits=mAimeskVpimesSimesextfactorext{Heat Units} = mA imes kVp imes S imes ext{factor}

  • Cooling Charts: Skipped as not needed.

  • Module Assessment: Don’t stress math questions.

3. Electrical Physics of X-ray Production

  • Watch:

    • Series Circuit & Parallel Circuit Lessons (basic understanding, stress less on math).

    • Describe differences between series and parallel circuits.

  • Ohm’s Law:

    • Define key terms:

    • Amperes: Unit of electric current.

    • Voltage: Electric potential difference.

    • Resistance: Opposition to current flow.

4. Radiographic Image Production - X-ray Circuit Section

  • X-ray Circuit Overview:

    • Find an image of the X-ray circuit, list components of:

    • Primary, secondary, and filament circuits and their roles.

    • Learn about transformers:

    • Incoming Voltage: Identify and its role.

    • Autotransformer:

      • Explain its type of induction (self-induction).

    • Step-up Transformer: Role described.

    • Step-down Transformer: Role described.

    • Rectifier's Role: Explain conversion from AC to DC.

    • Direct vs. Alternating Current: Distinguish which operates in circuits.

    • Rheostat: Define its role in controlling resistance.

    • **Analyze mA increase effect on
