IEC 62220-2-1:2023 describes the performance metrics associated with DUAL-ENERGY IMAGING capable DIGITAL X-RAY IMAGING DEVICES meant for medical applications and specifies the methods for their determination. These metrics can be used to analyse TISSUE-SUBTRACTED IMAGES and to evaluate dose performance, noise characteristics, and tissue-subtraction efficacy of DIGITAL X-RAY IMAGING DEVICES. The described methods indicate the procedures to obtain MULTI-SPECTRAL PRIMARY DATA and to compute their derived TISSUE-SUBTRACTED IMAGES.
The intended users of this document are MANUFACTURERS and well-equipped test laboratories. This document is restricted to DIGITAL X-RAY IMAGING DEVICES that are used for single or multiple exposure dual-energy radiographic imaging based on, for example, CR systems, direct and indirect flat panel-detector based systems.
This document excludes and is not applicable to:
– DIGITAL X-RAY IMAGING DEVICES intended to be used in mammography or in dental RADIOGRAPHY;
– slot scanning DIGITAL X-RAY IMAGING DEVICES;
– COMPUTED TOMOGRAPHY or CONE-BEAM COMPUTED TOMOGRAPHY;
– photon-energy discriminating devices such as photon counting X-RAY IMAGING DEVICES;
– devices for dynamic imaging (where series of images are acquired, as in fluoroscopy or cardiac imaging).
– DIGITAL X-RAY IMAGING DEVICES intended to be used with RADIOTHERAPY beams.

Standard IEC 62220-2-1:2023 opisuje meritev zmogljivosti v zvezi z RADIOGRAFSKIM SLIKANJEM Z DVOJNO ENERGIJO z DIGITALNIMI NAPRAVAMI ZA RENTGENSKO SLIKANJE, ki so namenjene medicinski uporabi, in podaja metode za njihovo določanje. To meritev je mogoče uporabiti za analiziranje SLIK ODŠTETEGA TKIVA in ocenjevanje učinkov pri odmerjanju, značilnosti hrupa in učinkovitosti odštevanja tkiva DIGITALNIH NAPRAV ZA RENTGENSKO SLIKANJE. Opisane metode navajajo postopke za pridobivanje MULTISPEKTRALNIH PRIMARNIH PODATKOV in računanje njihovih izpeljanih SLIK ODŠTETEGA TKIVA.
Predvideni uporabniki tega dokumenta so PROIZVAJALCI in dobro opremljeni preskusni laboratoriji. Ta dokument je omejen na DIGITALNE NAPRAVE ZA RENTGENSKO SLIKANJE, ki se uporabljajo za enkratno ali večkratno izpostavljenost radiografskemu slikanju z dvojno energijo, na primer na podlagi sistemov za računalniško digitalno radiografijo (CR), neposrednih in posrednih sistemov na podlagi ploščatih detektorjev.
Dokument ne vključuje in se ne uporablja za:
– DIGITALNE NAPRAVE ZA RENTGENSKO SLIKANJE, namenjene uporabi v mamografiji ali dentalni RADIOGRAFIJI,
– DIGITALNE NAPRAVE ZA RENTGENSKO SLIKANJE, ki skenirajo reže,
– RAČUNALNIŠKO TOMOGRAFIJO ali RAČUNALNIŠKO TOMOGRAFIJO S STOŽČASTIM SNOPOM,
– naprave za ločevanje fotonske energije, npr. NAPRAVE ZA RENTGENSKO SLIKANJE s štetjem fotonov,
– naprave za dinamično slikanje (pri čemer se pridobijo serije slik, kot pri fluoroskopiji ali slikanju srca).
– DIGITALNE NAPRAVE ZA RENTGENSKO SLIKANJE, namenjene uporabi z RADIOTERAPEVTSKIMI žarki.
