Cone-Beam Computed Tomography (CBCT)

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.
