imaging
3D Technology
• CBCT - Cone Beam
Computed Tomography
• CBVT - Cone Beam Volume
Tomography
• Technological advance
from traditional fan beam
CT
• Image data is a cylinder,
not a set of single slices

Windows Media
Audio/Video file
3D Technology
• One 18 second scan
• 194 degrees scan angle
• 300 snap shot images
taken with synchronized Xray pulses
• Stroboscopic effect for
maximum clarity of the
images
• Accumulated X-ray
exposure time is 2.8 – 8.3
seconds – reduced dose
3D Technology
Pulsed X-ray produces sharp images with less
dose.
3D Technology
• 300 basic images
• Proprietary 3D
reconstruction algorithm
• Image volume is
8 x 8 cm cylinder of 120
million voxels
• Voxel size 160 x 160 x
160 µm
• Corresponds to 3 lp/mm
(Nyquist)
3D Technology – Flat Panel
Planmeca ProMax 3D flat
panel imaging chain
X-ray Tube – Patient – Flat Panel
- Digital Image
Conventional imaging chain
with Image Intensifier
X-ray Tube – Patient – Image Intensifier – TV
Camera – Digital Image
Modern Flat Panel Technology for maximum
performance
3D Technology – Flat Panel
• Image intensifier has
both distortion and
brightness nonuniformity which is
absent from the flat
panel detector
• Image intensifier needs
periodical maintenance.
It has limited life span 36 years.
• It is sensitive to
magnetic or electrical
fields.
• It is over 60 years old
technology.
3D technology – Tube Current Modulation
• Different attenuation
properties across and
along the patient's head
• Tube current (mAs) can be
dynamically adjusted
• Reduces patient dose and
improves image quality

more
3D vs Medical CT
• Planmeca ProMax 3D:
• cone beam
• 194 degrees = half a circle
• 18 seconds scan
• 6 seconds pulsed X-ray
• Medical CT with 0.6 mm
slice:
• fan beam
• 16 spiral rounds
• continuous X-ray
Medical CT is decades old technology

Radiation dose
Medical CT 1200-3300 uSv
Dr Stuart White, UCLA
Dig. Pan 4.7-14.9 uSv
FMS 150 uSv
Dr Sharon Brooks, O of Michigan
• Radiation dose of CBCT 30- 900
µSv
• Same level as 5-10 panoramic
images
• Same level as full mouth series
with film
• Essentially lower than medical CT
• ProMax 3D 45-200 µSv (8 x 8
cm), 18 – 80 µSv (4 x 5 cm)
Low radiation dose compared to medical CT
