Quantitative Total Extensible Imaging (QTxI) is a software tool used to aid in evaluation and information management of digital medical images by trained medical professionals including, but not limited to, radiologists, oncologists, nuclear medicine physicians, medical imaging technologists, dosimetrists and physicists. The medical modalities of these medical images include DICOM CT and PET as supported by ACR/NEMA DICOM 3.0.
QTxI assists in the following indications:
• Receive, store, retrieve, display and process digital medical images.
• Create, display and print reports from those images.
• Provide medical professionals with the ability to display, register, and fuse medical images.
• Identify Regions of Interest (ROIs) and perform ROI contouring allowing quantitative/statistical analysis of full or partial body scans.
• Evaluate quantitative change in ROIs (total or partial body; individual ROI within individual) with 3D interactive rendering of images with highlighted ROIs.
Indications for use as stated in the FDA summary.
