EN 60601-1-3 para. 29.205 - Focus-Skin Distance
Paragraphs 29.205.1 - 29.205.3 of the above standard deal with preventing the use of
inappropriate focus/skin distances in order that the dose equivalent to the patient be
kept as low as reasonably achievable.
29.205.1 - Radiation Equipment for fluoroscopy
X-ray devices for fluoroscopy must feature characteristics that, during fluoroscopy, will
prevent focus-skin distances less than:
• 20 cm if the x-ray device is specifically for fluoroscopy
• 30 cm for other applications
Conformity is measured and checked visually. The x-ray system must comply with the
norm; this means that the operator is responsible for the verification. A focus/skin spac-
er device is an option made available by Ralco.
per collimatori dotati di metro
for collimators with tape measure
AVVISO
WARNING
Uso del metro retraibile in collimatori
dotati di questa funzione:
Il metro adottato è un metro standard
montato su apparecchiatura radiologica.
In questa applicazione il metro parte con
la misurazione con un valore che
corrisponde alla distanza fuoco/ bordo
inferiore del collimatore; la massima
estensione radiologica è di 2m max
anche se, per ragioni meccaniche, il
metro raggiunge 3 m max. A fine lettura
meccanica massima viene riportata la
scritta STOP.
Estendere e/o forzare il nastro del metro
oltre a questa misura causa i seguenti
inconvenienti:
• rottura del nastro oppure
• distorsione del nastro oppure
• l'impossibilità di fare rientrare il nastro
nell'alloggiamento perché è stata for-
zata la tenuta della molla sul nastro
creando una distorsione.
NOTA:
NON ESTENDERE IL NASTRO
OLTRE Il NECESSARIO E IN OGNI CASO
NON OLTRE LA SCRITTA STOP
Use of the retactable tape measure in
collimators with this feature:
The type of tape measure adopted is a
standard tape mounted on a
radiological unit. In this application the
tape starts with values that correspond
to the focus/collimator lower edge
distance; maximum radiological
measurement with the tape is 2 m max
even though, for purely mechanical
reasons, maximum tape extension is 3
m max. The indication of STOP is
evident immediately after the maximum
mechanical value.
Forcing and/or extending the tape
beyond this point with cause the follow-
ing inconveniences:
• Breakage of the tape or,
• Distortion of the tape or,
• Impossibility of retracting the tape
into its lodging because the grip of
the spring has been forced and
hook-up is consequently distorted.
NOTE:
DO NOT EXTEND THE TAPE
BEYOND THE INDICATION OF STOP
