Siemens Dyna CT Capabilities / Limitations
Doing 3DRA is very different from biplane Angio,
thus achieving top results demands long learning curve
Hardware - Software - Workflow

Siemens Dyna CT Capabilities / Limitations
Hardware
+ large detector 48cm, full thorax scan
+ large display, allows to organize information
- Acquisition Time (5s), adaptable, rotation scan faster (biplane ?),
=> less contrast
- monoplane rotational Acquisition
- so far no implementation / live overlay Echo - Angio

Software
+ 2 dataset levels two work with :
actual scan plus one merged dataset (CTA, MRA, former 3DRA),
actual scan duplication (show RH / LH, vessel versus airway etc)
+ airway, merge, duplicate, clipping, hollow figures
- 3D Workstation not linked to logistics for 3D print, CFD, …
- documentation of result suboptimal (fly through animation)
- Current PACS systems not ready to present 3D data adequately (pdf)
- How to export 3D data for surgical discussions ? AVI …. ???

Workflow
+ close contact Siemens / user
- Workflow : a lot of help but little knowledge at Siemens
- 3DRA : how to shorten learning curve ? teaching …
- Settings not transparent and suboptimal for CHD (1,5 / 0,8 degree/F)

3DRA ROADMAP
Roadmapping :
+ Project 3DRA on A plane
- B plane ? NO !
+ Safe contrast
+ revalidate position by control
angio
+ anatomic shift by stiff wires …
+ entrance in ostia “made easy”
