Evaluation and routine testing in medical imaging departments - Part 2-6: Constancy tests - Imaging performance of computed tomography X-ray equipment
This part of IEC 61223 provides assistance in performing constancy tests on a CT scanner. It applies to those components of CT scanners which influence the image quality, patient dose and positioning. This standard - defines the essential parameters which describe the performance of CT scanners with regard to image quality, patient dose and positioning; the list of parameters to be tested can be found in section 4.5; - defines the methods of testing the essential parameters; - provides criteria to be applied in the evaluation of data for compliance with the tolerances of the parameters specified by the accompanying documents and with respect to baseline values. These methods rely on non-invasive measurements, using appropriate test equipment, performed to ensure that the functional performance of equipment meets established criteria or to enable the early recognition of changes in the properties of components of the equipment. The aim is to verify compliance with specifications affecting the image quality, patient dose and patient positioning.

Essais d'évaluation et de routine dans les services d'imagerie médicale - Partie 2-6: Essais de constance - Performance d'imagerie des équipements de tomodensitométrie à rayonnement X
La présente partie de la CEI 61223 fournit une aide à la réalisation des essais de constance des tomodensitomètres. Elle s'applique aux composants des tomodensitomètres qui influencent la qualité de l'image, la dose patient et le positionnement. La présente norme - définit les paramètres essentiels qui décrivent les performances des tomodensitomètres concernant la qualité de l'image, la dose patient et le positionnement; la liste des paramètres à soumettre aux essais peut être trouvée au paragraphe 4.5; - définit les méthodes d'essai des paramètres essentiels; - fournit les critères à appliquer lors de l'évaluation des données pour établir la conformité aux tolérances des paramètres spécifiés par les documents d'accompagnement et concernant les valeurs de base. Ces méthodes reposent sur des mesurages non invasifs, utilisant des équipements d'essai appropriés, réalisés pour s'assurer que la performance fonctionnelle de l'équipement satisfait aux critères établis ou pour permettre une reconnaissance précoce des variations des propriétés des composants de l'équipements. Le but recherché est la vérification de la conformité aux spécifications concernant la qualité de l'image, la dose patient et le positionnement du patient.
Vrednotenje in rutinsko preskušanje v oddelkih za medicinsko slikanje - 2-6. del: Preskus konstantnosti - Rentgenska oprema za računalniško tomografijo (IEC 61223-2-6:2006)
Ta del IEC 61223 predpisuje pomoč pri izvajanju PRESKUSOV KONSTANTNOSTI pri RENTGENU ZA RAČUNALNIŠKO TOMOGRAFIJO. Velja za tiste komponente RENTGENOV ZA RAČUNALNIŠKE TOMOGRAFIJE, ki vplivajo na kvaliteto slike, odmerek na PACIENTA in pozicioniranje. Ta standard opredeljuje bistvene parametre, ki opisujejo zmogljivost RENTGENOV ZA RAČUNALNIŠKO TOMOGRAFIJO glede kvalitete slike, odmerka za PACIENTA in pozicioniranja; seznam parametrov, ki se jih preskuša, se nahaja v Razdelku 4.5.; - opredeljuje metode preskušanja bistvenih parametrov; zagotavlja merila za uporabo pri vrednotenju podatkov za skladnost z odstopanji parametrov, ki jih določajo SPREMNI DOKUMENTI in ob upoštevanju SREDNJIH VREDNOSTI. Te metode se opirajo na neinvazivna merjenja z uporabo primerne preskusne opreme in delujejo tako, da se za funkcionalno zmogljivost OPREME zagotovi, da izpolnjuje VZPOSTAVLJENA MERILA ali da omogoča zgodnje prepoznavanje sprememb lastnosti komponent OPREME. Cilj je potrditi skladnost s specifikacijami, ki vplivajo na kakovost slike, odmerka za PACIENTA in pozicioniranje PACIENTA. Njegov namen ni, da upošteva: - vidike mehanske in električne varnosti, niti - vidike mehanske in električne zmogljivosti ter zmogljivosti programske opreme, razen če so le-ti bistveni za izvajanje PRESKUSOV KONSTANTNOSTI in neposredno vplivajo na kakovost slike, odmerka za PACIENTA in njegovo pozicioniranje.

of the particular requirements for CT scanners.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-12-01
– latest date by which the national standards conflicting
(dow) 2010-03-01
with the EN have to be withdrawn
In this standard, the following print types are used:
