Radiologic Technology Basics and Fundamentals is a comprehensive guide designed for students, professionals, and anyone interested in the field of radiologic technology. This document provides a clear and concise overview of the foundational principles, techniques, and equipment used in diagnostic ...
High KE: High Kvp: high x-ray quality : high x-ray quantity
B. PROJECTILE ELECTRONS
electrons travels from cathode to anode
Interacts in tungten atom by tranferring its KE to W atom
Electron ins REST state
Projectile electron interaction
OUTER SHELL / INNER SHELL
NUCLEAR FIELD
Production of Heat/ Infrared/ radiation
99% HEAT
1 % x-ray
How:
electrons in exited state level / higher
energy level
NO IONIZATION of electrons
ANODE HEAT
Production:
high tube current: high heat
Interaction:
OUTER SHELL ELECTRONS
CHARACTERISTIC X-RAY 1% X- ray
INTERACTION: INNER SHELL ELECTRON
How?
X-RAY PRODUCTION 1
, Total removal of electron from the atom,
then outer shell fills the INNER VOID
ionized electron from K shell, Lshell
electrons fills the K shell void : emission of
x-ray : K- xrays….
only the K- characteristic x-rays are useful
in imaging
69 kVP
CHARACTERISTIC X-RAY SPECTRUM
ELECTRON BINDING ENERGIES
energy: fixed / discrete energies
K- xrays : only characteristic x-rays:
diagnostic x-ray
69 kev
BREMSSTRAHLUNG X-RAY 1% x-rays
INTERACTION: NUCLEAR FIELD
Braking of projectile electron
how?
Electrostatic Force between the nucleus
and projectile electron
projectile electron passes by the nucleus
and slows down and changes its course
leaving reduce KE
loss of KE: emission of x-ray
dependent on the loss KE
X-RAY PRODUCTION 2
