SkyView Into the third dimension
Image-based diagnostics:the evolution of excellence
Fifty years have passed since the first
clinical utilisation of pantomography in
the dentistry field. Effective, fast and
economic, this technique provides
an overall view of the dental arches
and adjacent anatomical structures.
In recent years it has evolved to
incorporate digital technology and,
for most dentists, has become not
just a technique but one of the
dental surgerys most common X-ray
equipment items, the panoramic
dental system.
The two-dimensional approach to
panoramic images generates data
requiring interpretation. In many
cases this does not give the required
level of precision: patient positioning
errors can make measurements
on the resulting image unreliable.
There may be non-uniform resolution
dependent on proximity to the
theoretical line along which the focal
layer runs. Above all, the technique
is limited by the overlapping of
anatomical structures belonging to
different planes in short, it is two-
dimensional.
It is necessary to interpret the
panoramic image to determine, for
example, whether an object is labial
or lingual, as there is no perception of
the missing dimension, depth.
SkyView takes you into the third dimension
Today, a new X-ray image diagnostic
revolution is under way, and it is already
changing dental treatment standards.
MyRay guides you towards the
discovery of this new horizon: the 3-D
X-ray imagery of SkyView.
You are about to be released from
the limitations of two dimensions
to discover true-to-life views of the
maxillofacial area.
Relax, and enjoy the experience.

Fast, safe imaging
SkyView adopts a new and
increasingly successful X-ray
technique, known as Cone Beam
Computed Tomography (CBCT),
ideal for obtaining three-dimensional
reconstructions of teeth and the entire
maxillofacial area. If compared to
more dated tomography techniques
such as hospital CAT scans, CBCT
has the advantage of acquiring images
The diagram illustrates the basic principle
behind CBCT technology. A source-detector
system rotates around the patients head; this
system consists of a cone-beam X-ray source
on one side and a state-of-the-art detector on
the other.
SkyView with 9 detector
Especially suitable for X-ray and
image-based diagnosis centres, the
15 cm-diameter spherical field of view
allows the entire maxillofacial
region to be framed in a single scan.
SkyView with 6 detector
By limiting the field of view to a sphere
with a diameter of 11 cm, SkyView can
produce high-resolution images of the
entire adult dentition, with minimal
X-ray doses.
The field of view can, however, be
shifted to frame other areas of interest,
such as the temporomandibular joints.
4 HR Zoom
Where necessary a variable X-ray beam
collimation system (HR Zoom) allows
the field of view to be narrowed further,
to give higher-resolution focussing of
smaller anatomical regions, to a sphere
just 7 cm in diameter.
with just one partial rotation of the
source-detector system around the
patient. Consequently, less time is
needed to perform the examination
and, above all, the patient is exposed
to a considerably lower X-ray dose.

Image Intensi er
SkyView is a tomographic system
based on a state-of-the-art detector: a
variable-field image intensifier offering
maximum contrast and maximum
definition with low X-ray doses. The
high sensitivity of the image intensifier,
the scan speed and the pulsed X-ray
emission system ensure that X-ray
doses are very low indeed; in fact,
by restricting the field of view to the
dentition only, doses are comparable to
Absolute diagnostic precision
After acquisition, SkyView proceeds
with volumetric reconstruction.
This fully automatic operation
generates a faithful, virtual
representation of the examined area,
free from distortion and measurable
with absolute precision whatever its
orientation.
The third dimension is now at your
fingertips, leaving you free to explore
a new world of diagnostic efficiency.
those of the panoramic X-ray systems
commonly used in dental practices.
So diagnostic potential is
enhanced but without increasing
the risk to the patient.
High de nition with low emissions
The technology is based on 3 main elements: A scintillator that converts radiation into a visible
image
A beam concentrator that intensifi es the image by a factor of 105
A high resolution CCD digital sensor consisting of pixels with a size of 7.4 m to detect the image.

Putting the patient at ease
SkyView clearly demonstrates the
achievements of MyRay research, aimed
at providing the very best diagnostic
experience for dentist and patient alike.
So MyRay has chosen to go the supine
way, conceived for total patient relaxation.
For the patient, the entire SkyView X-ray
imaging experience is, starting with
positioning, a comfortable one. The
Different by choiceSkyView The evolution of diagnostics
reclining patient chair is automatically
lowered into the access position to make
seating the patient easier; the patients
head is supported by the comfortable
headrest, a soft height-adjustable cushion
designed to stabilise the cranium; then
the chair stretches out to perform the
quick X-ray examination. The patient
can lie down and relax thanks to the
comfortable headrest; the fi eld of view
is unhindered and the whole procedure
is a pleasant anxiety-free experience,
simpler for both patient and dentist,
who maintains reassuring eye contact
with the patient during positioning.
Enhanced image quality
It has been demonstrated that patient
immobility is greatly enhanced when
patients are lying down and relaxed as
opposed to standing or seated. Image
quality is proportional to the immobility
of the irradiated subject, since even
Patient immobility is a fundamental prerequisite
for good extra-oral radiography, especially so
when 3-D images are acquired using the CBCT
technique.

Precision measurement
SkyView produces high defi nition images, completely free from geometric deformation, perfectly measurable with micrometric precision and reliable over time. Thanks to Isotropic Voxels, measurements are reliable and on a 1:1 scale whatever the reference plane of the measured sections.
Speed and comfort
The total lack of cephalostats, straps
or bites means that the patient
can be made ready for the X-ray
simply and quickly. This prevents
the downtimes normally associated
with seating the patient and
preparing them for the brief scan
that completes the examination.
No unpleasantness for the patient:
all they have to do is lie down and
rest their head on a soft cushion
specially designed to guarantee
stability.
During the examination, the detector
rotates - in just a few seconds -
around the table, without the patient
experiencing the unpleasant feeling of
being enclosed in a machine.

Preparation
SkyView has two simple, user-friendly,
instruments to identify the anatomical
region to be X-rayed: laser tracking or
software on an automatic console.
Tracking laser
As on the best panoramic systems, three laser
beams identify correct alignment of the region of
interest. The innovation here lies in the fact that
alignment is adjusted by controlling the motor-
driven bed via the dedicated keypad.
The control panel allows both pre-set movements
and fine adjustment.
Positioning is therefore precise and effortless
and also comforting as visual contact with the
patient is maintained.
Scout method
A software-guided procedure allows the
operator to align the region of interest
while remaining comfortably seated at the
PC workstation.
This method is extremely high-precision
and involves the acquisition of two
preview (Scout) X-ray images at extremely
low dosages; these previews are used
to identify the centre of volumetric
reconstruction.
By using the mouse cursor to adjust the
aiming device superimposed on the Scout
images, the motorised SkyView table will
automatically be repositioned to frame the
selected region.
These advanced positioning methods,
used alternatively or in combination,
ensure the X-ray will not have to be
repeated because of alignment errors.
SkyView is equipped with comprehensive software for the acquisition and processing of volumetric images.
Analysis of the maxillary and frontal sinuses, together with examination of airways, allows detection of certain pathologies such as: malformations, sinusitis and deviations of the nasal septum
3-D examination is a particularly effective means of studying relationships between impacted teeth and planning surgical treatment
Guided procedures help the user highlight the mandibular canal and define the best profile for a reconstruction panoramic, which will be unaffected by the geometrical limitations typical of conventional panoramic images: no cancellation, no spinal column shadow and, above all, uniform resolution.
with implants.
These views are interconnected and
colour-coded to aid exploration of the
anatomical structures.
All cross-sections and two-dimensional
reconstructions can be defined
according to modifiable profiles and the
user can select their thickness.
The supplied software allows
the user to manage one or more
X-ray directories, organised into
medical record folders. Each X-ray
examination can generate several
studies in that, once the volumetric
data has been acquired, it can be
used in several investigations during
different stages of the treatment
plan without any need for further
exposure.
Outstanding data control allows for bettertreatment planning
At the end of the acquisition/volumetric
reconstruction procedure, the dentist
will have multiple views of the patients
anatomy: a curvilinear cross-section
that resembles the panoramic image,
a moveable 3-D model, a coronal
cross-section that allows exploration
of the upper/lower dental arches, and
ten transverse cross-sections that are
especially useful for the linear and
angular measurements so often used
Data on tap
Easy installation
The radiation source is a 90 kV X-ray
tube, a power level comparable to that
of a panoramic dental system. This
allows the equipment to be installed
easily in any dental surgery: X-ray
shielding requirements are, in fact,
comparable to those of a panoramic
system.
Compact design
SkyView is a compact, professionally
designed device.
Minimum dimensions for a room in
which SkyView is to be installed are
approximately 160 cm x 250 cm. A
more spacious room will undoubtedly
enhance the users experience.
The room must allow easy access to
one of the two table sides; the control
panel can be installed on either side
of the patient table.
