CHED granted the Autonomous Status to Cebu Doctors’ University
May 27, 2010
When did the college produced the first batch of ART graduates
1978
The college offered the baccalaureate degree in Radiologic Technology
(BSRT) in
1980
The year ART and BSRT programs were made into separate programs
1987
The year CDU implemented the AHSE program
with the first two years resulting in an associate degree in Health Science Education.
1998
The year the BSRT curriculum underwent major revision to make the curricular offering responsive to the advancements in the field of radiological sciences, and to conform with the Vision, Mission and Goals of the college, and to comply with the CHED Policies and Standards for Radiologic Technology Education
1996
Physics came from the Greek word:
meaning:
physis “nature”
is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force.
Physics
Numbers between 1 and 10 multiplied by 10 raised to some exponent
Scientific notation
Part of a whole
Fraction
having an integer as numerator and an integer denominator
Fraction
A way of expressing a number of equal parts
Fraction
Types of Fraction
- Improper fraction
- Proper fraction
- Mixed Fraction
Are special application of fractions
Ratios
express the mathematical relationship between similar quantities
Ratios
is a name we give to a statement that two ratios are equal
Proportion
Express the relationship of one ratio to another and it is a special application of fractions and rules in algebra.
Proportion
A relationship when one ratio increase with respect to another ratio
Directly proportional
A relationship when one ratio decrease with respect to another ratio
Inversely proportional
1 R
2.58 x10^-4 C/kg
It is another radiation quantity that is sometimes used to express the radiation concentration
delivered to a point, such as the entrance surface of a patient’s body.
Air Kerma
KERMA
Kinetic Energy Released per unit
Mass of Air
It is a measure of the amount of radiation energy, in the unit of joules (J), actually deposited in or absorbed in a unit mass (kg) of air.
Air Kerma
Kerma, is expressed in the units of ____ which is also the radiation unit, the ___
J/kg,
Gray (G)
The concentration of radiation energy absorbed in a material is
Absorbed Dose
a measure of radiation based on the ability to produce ionization
Exposure dose
the energy of ionizing radiation absorbed per unit mass by a body
Absorbed dose
relates to the overall long-term risk to a person from a procedure
Effective dose
the process of spontaneous breakdown of unstable (or radioactive) nuclides
Radioactivity
The type of x-rays is emitted during electron capture
Characteristic
