MAP 255 - Diagnostic Radiography I

Credits: 3
Lecture Hours: 1
Lab Hours: 4
Practicum Hours: 0
Work Experience: 0
Course Type: Voc/Tech
This course builds the foundation of knowledge and skills necessary to qualify as a candidate for the Iowa state permit examination in Limited Radiography. Students will be introduced to and form a reasonable understanding of the scientific basis of radiography. Students will journey to a full understanding of x-ray production, exposure factors, photographic and geometric factors of image formation, digital radiography as well as radiation biology and safety. As students work through principles of radiography they will be encouraged to build critical thinking skills that will require psychomotor as well as affective domains to assess patients, evaluate images, resolve processing issues and utilize concepts of radiation safety in the areas of occupational practice as well as patient care.
Prerequisite: MAP 544   with a C or better
Competencies
  1. Define the role and scope of the Limited Radiographer as defined in the State of Iowa Administrative Code
    1. Identify the Scope of Practice for Limited Radiography as defined by the State of Iowa.
    2. Cite the legal requirements for obtaining a Permit to Practice Limited Radiography in the State of Iowa.
    3. Identify providers/practitioners who are licensed to order radiographic examinations.
    4. Identify who is responsible for image interpretation.
    5. Demonstrate knowledge of rules of confidentiality as well as the role that HIPAA plays in custody of images.
  2. Examine basic principles of electricity and electromagnetic energy, students will develop knowledge and understanding of x-ray production
    1. Identify components of x-ray production; source of electrons; acceleration of electrons; focusing of electrons; deceleration of electrons.
    2. Identify interactions that produce x-rays: bremsstrahlung, characteristic.
    3. Identify properties of the x-ray beam: frequency and wavelength; beam characteristics; inverse square law; fundamental properties.
    4. Describe photon interactions with matter: Compton effect; photoelectric absorption, coherent scatter; attenuation by various tissues.
    5. Describe the relationships of wavelength and frequency, including the relationship to beam characteristics.

    1. Identify the location of anatomical structures using direction and orientation terms.
    2. Indicate where various planes lie in relation to the body.
    3. Demonstrate the use of topographical landmarks to locate internal structures.
    4. Identify and locate the bones of the upper extremity (head of the humerus to the distal tip of the digits)
    5. Identify and locate the bones of the lower extremity (head of the femur to the dital tip of the pedal digits)
    6. Identify and locate the bones, organs and structures found in the chest cavity.
    7. Identify and compare classifications of body habitus.
    8. Demonstrate standard positioning and procedure terminology.
    9. Demonstrate body and radiographic positions.
    10. Demonstrate proper use of anatomic relationships and locations.
    11. Apply the proper use of body planes when positioning patients for radiographic examinations.
    12. Demonstrate proper use of positioning aids.
  4. Assess skills that pertain to the performance of radiographic examinations included in the Scope of Practice 
    1. Identify the structures demonstrated on routine radiographic images.
    2. Simulate radiographic procedures on a person, phantom, or simulator application.
    3. List and explain the routine and special projections for radiographic examinations included in the Scope of Practice.
    4. Demonstrate the ability to fully explain radiographic procedures to patients and family.
    5. Demonstrate the ability to modify directions when patients present with communication challenges.
    6. Apply general radiation safety and protection practices associated with radiographic examinations.
    7. Define basic terms related to pathology that are used to classify and identify diseases.
    8. Discuss general procedural considerations for radiographic examinations and demonstrate the ability to adapt these considerations to specific clinical settings
