A Case Collection Study for Digital Breast Tomosynthesis (DBT) Using the Senographe Essential

Completed

• Conditions: Image Correction
• Interventions: Radiation: Digital Breast Tomosynthesis

• Registration Number: NCT01885143
• Lead Sponsor: GE Healthcare

Brief Summary

Collect clinical images requested by FDA with GE Breast Tomosynthesis to show they are of acceptable quality as defined in the relevant FDA guidance document before and after artifact correction and in standard screening images. Lossy compression will also be evaluated to demonstrate that images are of acceptable quality when lossy compression is enabled.
