AutoQALite Software for use with the CatPhan CT Phantoms.

An updated Windows program to the original PC/AutoQA for CT. This update provides expanded image processing capacity for up to 96 images in a data set with a comprehensive trend analysis feature.

PROCESSING FEATURES

CT AutoQA Lite™ can be configured with various vendor phantoms including ACR and all Catphan® models.
CT AutoQA Lite™ is DICOM3.0 compatible, a DICOM Storage Provider （SCP） Application license is provided.
CT AutoQA Lite™ provides the same analysis function as the original PC/AutoQA （DOS） version.

Pixel Size – test verifies the expected pixel size based on the display field of view and the reconstruction matrix size from the measured set of four calibration pins positioned at a known physical location as specified in the Catphan® section CTP401 and CTP404
