Leeds to PIX 13 phantom

The Leeds Test PIX 13 phantom had been designed to check the image quality of digital X-ray systems. These tests must be conducted during the acceptance of an X-ray system and when establishing a QA baseline. PIX 13 is used on a routine basis and it retains test results that in an interim evaluation (status test) could indicate degradation of performance. This PIX 13 phantom is used in combination with PMMA/Cu or Al patient-equivalent phantom filters (available separately) and can be supplied with a software analysis package.
