Determination of the maximum symmetrical radiation field of X-ray tube assemblies and X-ray source assemblies for medical diagnosis

This International Standard is applicable to X-RAY SOURCE ASSEMBLIES and X-RAY TUBE ASSEMBLIES, for use in MEDICAL DIAGNOSTIC RADIOLOGY for techniques in which the X-RAY PATTERN will be received simultaneously in all points of the IMAGE RECEPTION AREA. This standard specifies a method for the determination of the greatest geometrically symmetrical RADIATION FIELD at a specified distance from the FOCAL SPOT for which the percentage AIR KERMA RATE along the major axes of the RADIATION FIELD does not fall below a permitted value. NOTE 1 AIR KERMA or AIR KERMA RATE are the only practical verifiable physical quantities for X-RAY SOURCES. X-RAY SOURCES must be tested independently from MEDICAL ELECTRICAL SYSTEMS. Conversion to the characteristics of the X-RAY IMAGE RECEPTOR used in a MEDICAL ELECTRICAL SYSTEM may be done in addition. In case multiple FOCAL SPOTS are not super-imposed, each focal spot has its own REFERENCE AXIS. Then the maximum RADIATION FIELD may be given for each FOCAL SPOT separately NOTE 2 The maximum symmetrical RADIATION FIELD may change from its initial value as the X-RAY TUBE ages through use. NOTE 3 If, for certain MEDICAL ELECTRICAL SYSTEMs the scope of IEC 60806 does not fit, then the special RADIATION FIELD requirements could be incorporated in the MEDICAL ELECTRICAL SYSTEM particular standard. However, a statement on the RADIATION FIELD while referring IEC 60806 is then no longer possible.

Bestimmung des maximalen symmetrischen Strahlenfeldes von Röntgenstrahlern und Strahlern einschließlich Blendensystem für medizinische Diagnostik

Dieses Dokument ist anwendbar für STRAHLER EINSCHLIESSLICH BLENDENSYSTEM und RÖNTGENSTRAHLER. ANMERKUNG 1 Falls für bestimmte MEDIZINISCHE ELEKTRISCHE SYSTEME besondere STRAHLENFELDER erforderlich sind, so dass diese nicht in den Anwendungsbereich der IEC 60806 fallen (z. B. bei Verwendung von CT-Kollimatoren mit Bowtie-Filtern), gilt die entsprechende Systemnorm. Dieses Dokument legt ein Verfahren zur Ermittlung des größten, geometrisch symmetrischen STRAHLENFELDES in einem angegebenen Abstand vom BRENNFLECK fest, in dem die prozentuale LUFTKERMALEISTUNG entlang der Hauptachsen des STRAHLENFELDES nicht unter einen zulässigen Wert absinkt. ANMERKUNG 2 In der Praxis sind LUFTKERMA oder LUFTKERMALEISTUNG die praktischsten physikalischen Größen zur Quantifizierung von RÖNTGENSTRAHLENRELIEF. Wenn sich mehrere BRENNFLECKE nicht überlagern, hat jeder Brennfleck seine eigene REFERENZACHSE. Dann kann das maximale STRAHLENFELD für jeden BRENNFLECK separat angegeben werden. ANMERKUNG 3 Das maximale symmetrische STRAHLENFELD kann von seinem Ausgangswert abweichen, da die RÖNTGENRÖHRE durch Benutzung altert.

Détermination du champ de rayonnement maximal symétrique des gaines équipées et des ensembles radiogènes utilisés en diagnostic médical

L'IEC 60806:2022 s'applique aux ENSEMBLES RADIOGENES et aux GAINES EQUIPEE. Le présent document spécifie une méthode pour la détermination du plus grand CHAMP DE RAYONNEMENT de géométrie symétrique à une distance spécifiée du FOYER pour laquelle le pourcentage de DEBIT DE KERMA dans l’air le long des axes principaux du CHAMP DE RAYONNEMENT, ne diminue pas pour atteindre une valeur inférieure aux valeurs autorisées. S'il n'y a pas superposition de FOYERS multiples, chaque FOYER possède son propre axe de référence. Ainsi, le CHAMP DE RAYONNEMENT maximal peut être donné individuellement pour chaque FOYER. L'IEC 60806:2022 annule et remplace la première édition parue en 1984. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) ajout des détecteurs à semiconducteur dont l'usage s'est répandu depuis la première édition de 1984.

Določanje maksimuma simetričnega sevalnega polja rentgenskih cevi in rentgenskih žarkov za medicinsko diagnostiko (IEC 60806:2022)

Ta mednarodni standard se uporablja za RENTGENSKE VIRE in RENTGENSKE CEVI za MEDICINSKO DIAGNOSTIČNO RADIOLOGIJO za tehnike, pri katerih bo RENTGENSKI VZOREC prejet istočasno v vseh točkah OBMOČJA SPREJEMA SLIKE.
Ta standard določa metodo za določanje maksimuma geometrično simetričnega SEVALNEGA POLJA na določeni razdalji od GORIŠČA, pri katerem odstotek STOPNJE KERME V ZRAKU vzdolž glavnih osi SEVALNEGA POLJA ne pade pod dovoljeno vrednost.
OPOMBA 1: KERMA V ZRAKU ali STOPNJA KERME V ZRAKU sta edini praktično preverljivi fizikalni količini za VIRE RENTGENSKIH ŽARKOV. VIRE RENTGENSKIH ŽARKOV je treba preskusiti neodvisno od ELEKTROMEDICINSKIH SISTEMOV. Dodatno se lahko izvede pretvorba v značilnosti RECEPTORJA RENTGENSKE SLIKE, ki se uporablja v ELEKTROMEDICINSKEM SISTEMU.
V primeru, da več GORIŠČ ni prekritih, ima vsaka goriščna točka svojo REFERENČNO OS. Maksimum SEVALNEGA POLJA se tako lahko poda za vsako GORIŠČE posebej.
OPOMBA 2: Maksimum simetričnega SEVALNEGA POLJA se lahko spremeni od svoje začetne vrednosti, ko se RENTGENSKA CEV z uporabo stara.
OPOMBA 3: Če področje uporabe standarda IEC 60806 za določene ELEKTROMEDICINSKE SISTEME ni primerno, se lahko posebne zahteve za SEVALNO POLJE vključijo v poseben standard za ELEKTROMEDICINSKE SISTEME. Vendar izjava o SEVALNEM POLJU ob sklicevanju na IEC 60806 potem ni več mogoča.
