introduction
This procedure based on JJF1002-2010 "national verification procedures writing rules" and JJF1001-2011 "Tong
Metering term and definition of "establishment.
Metrological characteristics and test methods panoramic dental X-ray radiation source with reference to the GB/T 19042.4-2005 /
IEC 61223-3-4.2000 "evaluation of medical imaging departments and routine testing - Part 3-4. dental X-ray set
Imaging equipment performance acceptance test "and JJG 744-2004" Medical Diagnostic X-ray radiation "set forth in the respective
Provisions.
This procedure was first formulated.

3 terminology and units of measurement
3.1 Terms
3.1.1 Air Kerma airkerma
The sum of the initial kinetic energy of the ionized particles in the uncharged mass dm of air released from all of the charged particles
dEtr divided dm, symbol K.
K =

dm
3.1.2 air kerma rate airkermarate
Dt increase the amount of time in the air kerma dK divided by dt, symbol K
dK
dt
3.1.3 Spatial resolution spatialresolution
In the images under high contrast conditions can distinguish between two adjacent objects ability.
3.1.4 Low contrast resolution lowcontrastresolution
And the ability to distinguish between homogeneous mass of low contrast objects.
3.1.5 half-value layer half-valuelayer
Will reduce the amount of radiation particles unidirectional flow to decrease the thickness of the initial value of half time, the symbol for the HVL.
