complete solution 2025
Who discovered X rays?
Wilhelm Roentgen, November 8, 1895
What are the x-ray modalities?
General Radiography: basic x-ray images
CT (computed tomography): cross-sectional imaging using x-rays and computer processing
Mammography: breast imaging
Fluoroscopy: real-time moving x-ray images
Bone densitometry (DEXA): measures bone mineral density
How do they differentiate them? (x-ray modalities)
each modality varies in equipment, technique, and the type of image or information it provides.
What are three major categories of learning clinical skills?
Cognitive: knowledge and understanding
Psychomotor: physical tasks and skills
Affective: attitude and communication
What are the three phases of a clinical setting?
observation
assistance
performance
Who is a radiologist
a medical doctor who specializes in diagnosing and treating diseases using medical imaging. (x-
rays, CT, MRI, etc)
Certification
,voluntary process through which an agency grants recognition to an individual on demonstration
of specialized professional skills, usually through an examination
Accredidation
voluntary peer-review process through which an agency grants recognition to an institution for a
program of study that meets specified criteria.
Licensure
state-issued legal permission to practice
What is your title as a radiographer after you're licensed?
Registered technologist , radiographer
What is the problem-solving process?
identify the problem, investigate the problem,
formulate viable solutions to the problems,
select the best solution
Do you do more clinical or didactic education as you progress in the program?
More clinical as you progress, applying knowledge in real settings.
What is radiation therapy?
Uses very-high-energy ionizing radiation to treat malignant tumors (cancer)
What is nuclear medicine?
Uses the energy of the atom to create medical images
What is nuclear medicines energy form?
gamma radiation
What is an ultrasound?
imaging technique using high-frequency sound waves to view internal organs in real time
Date and discovery of x-rays
, November 8, 1895
Who certifies you after the exam?
ARRT (American Registry of Radiologic Technologists)
Qualities of critical thinkers
analytical, inquisitive, creative, logical, open-minded, reflective
What is mammography?
medical imaging technique that uses low-dose x-rays to create images of the breast. it's used to
screen for and diagnose breast cancer and other breast conditions.
What is bone densitometry?
uses x-rays to measure bone density. (DEXA scan)
What are the components of the X-ray tube?
1. Vacuum: glass/metal envelope (tube housing)
2. Source of electrons- filament of CATHODE
3. Target for electrons to strike- ANODE
4. High Voltage- to accelerate electrons towards targets.
Primary Radiation
exits x-ray tube via tube port directed towards patient.
Scatter Radiation
Emitted in all directions from the patient
Remnant Radiation
composed of scatter and transmitted primary radiation directed toward the image receptor
What is thermal energy?
energy from the motion of atoms/molecules. Heat
What is fluoroscopy?
