Note
The exam parameters set as the default are values to be taken as the starting point.
Users can optimise the parameters according to their needs.
Note
The new I-MAX 3D is based on a standard dentition and ascending rami shape. This
shape, based on statistical studies, establishes a form for the dentomaxillofacial
complex, adopted as "standard". I-MAX 3D follows a rototranslation path which
maintains the magnification factor as stated in the Technical Characteristics of each
type of exam as constant along this "standard" shape and in the dentition area. The
patient’s anatomy can differ significantly from the statistical model, so the magnification
factor is not maintained and can be different from the value stated. Based on his
experience and competence, the user has to judge this variation.
IN ANY CASE, RADIOGRAPHY IMAGES CANNOT BE USED TO PERFORM
CALCULATIONS OF DISTANCES, ANGLES ETC. ON THE IMAGE.
Warning
The measurement of lengths on digital images depends on the specific length
calibration of the programme used.
It is therefore very important to check the length calibration of the programme.
To obtain the measurement of the anatomical part, taking into consideration the
enlargement factor, the length calibration factor is:
•
100 pixels = 9.4 mm (in the centre of the focus layer) in 2D Panoramic and
Sinus exams.
•
100 pixels = 9.6 mm (in the centre of the focus layer) in 2D TMJ exams.
