• HISTORY
➢ Discovered November 8, 1895
➢ Discovered by Wilhelm Conrad Roentgen
o Discovered during his work with Crookes Tubes
➢ Roentgen’s wife’s hand was the first radiograph
• BASIC TERMINOLOGY
➢ Energy: ability to do work
➢ Radiation: energy traveled in a wave form through space or a medium
➢ X-ray: electromagnetic radiation of short wavelength that is produced when
electrons moving at high velocity are suddenly stopped
➢ Radiography: making of records of internal structures of the body by passing x-
rays or gamma rays through the body to act on specially sensitized film or an
image receptor
➢ Radiologic Technology: science of using radiation for diagnostic or therapeutic
reasons
➢ Radiographer: term used to identify individual who creates the image
➢ Radiologist: physician who specializes in reading images; they can diagnose and
treat patient
• SPECIALIZATION AREAS
➢ Mammography (M): Radiograph of the breast
o Secondary
➢ Computed Tomography (CT): Recording of a predetermined plane in the body
using an x-ray beam that is measured, recorded, and then processed by a
computer for display on a monitor
o Secondary
➢ Ultrasound (sonography) (S):
o Breast sonography
o Vascular sonography
❖ Primary and Secondary
➢ Radiation Therapy (T): Branch of radiology involved in the treatment of disease
by means of x-rays or radioactive substance
o Primary and Secondary
➢ Magnetic Resonance Imaging (MR): Process of using a magnetic field and
radiofrequencies to create sectional images of the body
o Primary or Secondary
, ➢ Nuclear Medicine Technology (NM): Branch of radiology that involves the
introduction of radioactive substances into the body for both diagnostic and
therapeutic purposes
o Primary or Secondary
➢ Interventional
o Cardiac Interventional (CI)
o Vascular Interventional (VI)
❖ Primary or Secondary
➢ Bone Densitometry (BD): Measurement of bone density using dual-energy x-ray
absorptiometry to detect osteoporosis
o Secondary
➢ Radiologist Assistant (RA): An advanced-level radiographer who extends the
capacity of the radiologist in the diagnostic imaging environment, thereby
enhancing patient care
o Primary or Secondary
• THE HEALTH CARE TEAM
➢ M.D./D.O.
➢ Midlevel practitioners
o PA, MP, Nurse Midwife, Nurse Anesthetist
➢ Nursing
o CNA, LPN, RN
➢ Allied Health
o Radiologic Technology
o Diagnostic/Therapeutic services
• WHAT HAPPENS THEN YOU COMPLETE THIS PROGRAM?
➢ Certification Exam
o ARRT
❖ R.T. (R)
➢ Continuing Education
o 24 credit hours biennium
• CERTIFICATION VS REGISTRATION
➢ Certification: deals with the demonstration of minimum competencies in

➢ Registration: a national registry (list) of certified individuals as proof of
achievement
,CHAPTER 17 INFECTION CONTROL
• INFECTION
➢ The establishment and growth of a microorganism on or in a host
➢ Microbial infection: organisms too small for the human eye
o Can be found in/on:
❖ Soil
❖ Water
❖ Plants/animals
❖ Human skin
❖ Nasal passages
❖ Intestinal tract
➢ Major cause of death in 1900
o Pneumonia
o Tuberculosis
o Diphtheria
➢ The treat still exists today in developing countries and immunosuppressed
patients
• DISEASE
➢ Deviations from or interruptions of the normal structure or function of any part,
organ, or system of the body that are exhibited by characteristic set of symptoms
and signs and whose cause, pathologic mechanism, and prognosis may be known
or unknown
➢ Signs: objective – can see or measure
➢ Symptoms: subjection – something that the patient describes to the doctor;
feeling, pains, etc.
• PATHOGEN
➢ Any disease producing organ
o Bacteria
o Virus
o Fungi
o Protozoan parasite
➢ Can multiply in large numbers, causing obstruction
o Blockage
o Lesions
➢ Can cause tissue damage
o Necrosis
➢ Can secret organic substances called exotoxins
, o Cell death
o Cell malfunction
❖ SIDE EFFECTS OF EXOTOXINS
Elevated body temperature
Nausea
Vomiting
Shock
Sepsis
• BACTERIA
➢ Prokaryotes
o Single celled organisms that lac nuclei and membrane-bound organelles
o No capacity to ingest particles or liquid droplets
o May reside in host in the form of a colony
o Can form endospores
❖ Wall to keep bacteria alive
➢ Bacteria Morphology
o Spirals
o Rods
o Spheres
➢ Types of bacterial infections
o Streptococcal pharyngitis (strep throat)
o Klebsiella pneumoniae (bacterial pneumonia)
o Clostridium botulinum (food poisoning)
• VIRUS
➢ Intracellular parasites
➢ Must live within a cell (host)
➢ Lack the ability to synthesize proteins
➢ Not treated with antibiotics
➢ Do not form endospores
➢ Viral infection process
o Virion attaches to the host cell and inserts genetic information into the
cell
o The virus uses the metabolic functions of the host cell to produce new
viruses
o New viral particles are then released
o Sometimes results in destruction of the host
➢ Types of viral infections
o Rhinovirus (common cold)
