A3. Basic applications of the Image-Vet 70ACP
A3.1. Basic patient position
The patient should be positioned on the table in whatever position that is
appropriate for the radiograph to be taken.
A3.2. Positioning the X-ray tubehead assembly
Position the tubehead by moving the double-jointed scissors arm so as to
bring the collimator into contact with the patient’s skin at the point where the
radiograph is to be made. The X-ray tubehead is set to the correct position
by using the bisecting angle technique
A3.2.1. Bisecting angle technique
a) Vertical incidence angle of the main beam:
In order to obtain a precise image of the tooth, the main beam must be
perpendicular to the bisector of the angle created between the longitudinal
axis of the tooth and of the film. Having positioned the tube head and the
film, as said above, an average incidence angle can be used for each area.
The incidence angle of the main beam can be determined by using the
graduated scale located on the bracket of X-ray tube. The diagram at the
side shows an example of positioning the X-ray cone using the bisecting
technique.
A3.2.2. Interproximal radiographs
To carry out this type of radiograph, the tubehead must be perpendicular
to the surface of the film.
