Generating slices, even when thick, gives depth information and removes the problem of superposed anatomy in projection radiography which can hide pathologies behind dense tissue.
Due to the limited angle sweep, tomoynthesis is not equivalent to CT, but gives sufficient depth information to look behind dense structures.
Typical clinical applications are: Orthopedics (microfractures, weight bearing exams), Pneumology (lung nodule detection), Urology (kidney stones),…
Tomosynthesis is an upgraded GenRad exam, filling the gap between 2D GenRad and CT:
- Dose levels comparable to a GenRad exam
- Workflow significantly faster than CT
- GenRad-size field of view
- GenRad in-plane resolution
