HISTORY REVIEW
• WHO
• WHAT
• WHEN
• The discovery of X rays by the German physicist
Wilhelm Roentgen in 1895 was an international
sensation.
• Working with vacuum tubes, he bombarded a metal
plate with high speed electrons.
• He found that invisible rays were produced. These
mysterious new rays could go through skin and
flesh and give a picture of a person's bones.
Collaborative Events

Crookes tube
 Air evacuated glass tube
 Cathode side
 Anode side
 Electrical supply
 Screen or board painted with barium
platinocyanide
 Low light work area
X-rays – the Basic Radiological Tool
Roentgen’s experimental apparatus (Crookes
tube) that led to the discovery of the new
radiation on 8 Nov. 1895 – he demonstrated
that the radiation was not due to charged
particles, but due to an as yet unknown
source, hence “x” radiation or “x-rays”
Known as “the radiograph of
Bertha Roentgen’s hand” taken
22 Dec. 1895

Today !
“Willie Roentgen”
• Honored in 1901
with the first
Nobel prize in
physics for his
efforts.
X-ray production begins
at the atomic level
Energy (photons) are released when
the electron collides with another electron,
the change in e of the shells –produces photons
More on this

SAFETY
TO SELF
& OTHERS
Early years in Radiologic
Technology
• Nurses or nurses aides taught how to
“take an x-ray”
• NO special education
• Only “ON THE JOB” training
• Experience the best teacher
• The first Technologist is credited to be
EDWARD C. JERMAN.
NATIONAL LICENSURE
ARRT
arrt.org
• 275,000 Registered RT (R)
• 2007: 15,285 exams
– 89% Radiography
– 3.6 % Nuclear Med
– 7.1 Radiation Therapy
Consumer Assurance of
Radiologic Excellence
The (CARE) bill
• would ensure that patients undergoing all
types of radiologic procedures
• have the same assurance of quality as
those receiving mammograms
• under the provisions of the Mammography
Quality Standards Act.
CARE BILL
• Consistency, Accuracy, Responsibility, and
Excellence...
ARRT Among Supporters Seeking To
Ensure Patient Safety Through
Adoption of CARE Bill
• ASRT – American Society of Radiologic
Technologist ASRT.org
As of Sept 2001- 16 states have no licensure laws
