DDA System Evaluation and Process Control
Each Duplex Plate Phantom per E2737 is custom made to order to fit your testing requirements. The standard ASTM E2737 describes the evaluation of DDA systems for industrial radiology. It is intended to ensure that the evaluation of image quality, as far as this is influenced by the DDA system, meets the needs of users and their customers and enables process control and long term stability of the DDA systems.
Test parameters include kV/mA, focal spot size, pre-filtering, geometric magnification, detector mode, number of image integrations, and exposure time.
These tests are to monitor the system performance for degradation and to identify when action needs to be taken if the system degrades by a certain level - i.e. influenced after repairs, hardware / software upgrades.
Described in ASTM E2737 but also for special inspection set-up dimensions, only.
