Overview of Upcoming Test

Test for module covering chapters 1, 2, and 4.
Originally scheduled for Monday, now postponed to Wednesday to allow adequate preparation time.
Review posted in the exam module to help students familiarize themselves with the material.
Emphasis that the test content will derive from the textbook and related PowerPoint presentations.

The review does not have to be completed, but serves as a helpful resource for understanding what material needs to be covered.
Students should refer to textbook questions and notes in PowerPoints to prepare adequately.

Students need to confirm that they have understood their observation requirements and instructions.
Observations are scheduled. If issues arise (e.g., bad weather), students should contact the instructor to reschedule.
Importance of checking in with the front desk on the day of observation to avoid delays.
Encourage proper professional behavior: arrive on time, dress appropriately, avoid using phones.

The first discussion board is optional; participation could positively impact overall discussion board scores.
It is beneficial to complete the discussion board as it contributes to easy credit.

Radiography involves various modalities and the use of energy to create diagnostic images.
Fundamental modalities discussed:
- CT (Computed Tomography): Employs x-rays to produce cross-sectional images and overcomes superimposition issues.
- MRI (Magnetic Resonance Imaging): Uses radio waves and magnets for imaging soft tissues.
- Ultrasound: Utilizes sound waves for imaging, effective for targeting soft tissue anatomy.
- Nuclear Medicine: Demonstrates both anatomy and function; effective in visualizing physiological processes.
Importance of cross-sectional imaging and comparative modalities in diagnostics.

Definition of radiation: Energy that can be transmitted through matter; includes ionizing radiation which has potential health hazards.
Distinction between ionizing radiation (which can create biochemical changes by adding or subtracting electrons) and non-ionizing radiation.
Legal and safety responsibilities of radiographers to minimize radiation exposure through proper training and adherence to standards.

Clarence Dally: First known casualty of radiation exposure due to x-rays in early experimentation in the field (Edison’s assistant).
Initial naïveté regarding radiation led to careless usage and regrettable consequences.

Role of a radiographer is primarily to produce diagnostic quality images for patient care.
Collaboration with other healthcare professionals is essential in delivering comprehensive patient care.

Radiologist: Medical doctor specializing in interpreting medical imaging; responsible for diagnoses.
Radiographer: Healthcare professional that performs radiographic imaging; does not diagnose conditions.
Technologist vs. Technician: Technologists have a higher level of training and responsibility; technicians operate under guidance.

Radiographers must hold certification (ART recognized) and, often, state licensure to practice legally.
Continuing education is required to maintain registration and licensure due to technological advancements.
The ART recognizes that certifications imply that the individual has passed examinations proving their competency.

Radiographers must operate within established practice standards; unethical practices can lead to legal repercussions and compromised patient safety.

Professional societies (e.g., ASRT) provide resources, advocate for members, and help maintain standards within the profession.
Importance of involvement in professional organizations for continuous development and support in careers.

ARRT: American Registry of Radiologic Technologists; certifies radiographers and manages registry.
JRCERT: Joint Review Committee on Education in Radiologic Technology; accredits radiologic educational programs.
Licensure: Grant of permission by a state government agency to practice a profession; required in many states including Texas.
