A range of simple to complex targets are precisely placed within tissue-equivalent breast, adipose and glandular materials.2 This uniquely flexible phantom design helps ensure efficiency across systems and test types. It can be used to evaluate Mammography and Tomosynthesis systems.
Save time and simplify Tomosynthesis QC
Whether your system uses angular range or step and shoot technology, the Modular DBT Phantom can support your needs. The phantom is designed for acceptance testing, daily and routine QC.
Tomosynthesis reconstruction showing BBs aligned in the x, y, and z-axis in a 4.5 cm stack; may be used for 2D and 3D accuracy.
|Modules and Targets||Tomosynthesis QC Test||Physicist|| Technologist
|Aluminum Alloy Sheets||CNR, ESF, Volume Coverage, 2D and 3D Accuracy|
|Tungsten Wires||MTF, LSF, 2D and 3D Accuracy|
|Barium Grooves||Missing Tissue at Chest Wall|
|BBs aligned in x, y, and z-axis||2D and 3D Accuracy, Artifact Evaluation, Flat Field 3D|
|Calcifications, Masses, Fibers||Image Quality, Routine Clinical Assessment, 2D and 3D Accuracy|
|Rounded Edge, No Targets||Decrease Artifacts in Reconstruction|
Left: Flat Field Tomo Protocol at 34 kVp; Right: Tomosynthesis Projection at 33 kVp. Test Contrast to Noise Ratio, ESF or 2D and 3D Accuracy with the overlapping sheets of Aluminum Alloy.
The barium-filled grooves support testing for missing tissue at the chest wall.
Projection image at 29 kVp, 4.5 cm module stack with Tungsten Wires and BBs.
Optional Glandular Breast and Adipose Breast homogeneous modules are available.
The following tests1 can be performed using the Modular DBT Phantom:
Tomosynthesis reconstructions include Tungsten Wires and Barium Grooves. These modules may be used to test MTF, LSF and missing tissue at the chest wall.
