SieClear
Siemens' spatial-compounding ultrasound imaging technology. Acquires multiple steered-angle scan lines per frame (up to 13 lines of sight on ACUSON Antares-era implementations) and combines them into a single compound image. Spatial compounding reduces speckle, sharpens tissue borders, and improves diagnostic confidence on technically difficult patients. Analogous to Philips SonoCT and GE CrossXBeam as compound-imaging approaches within each OEM's ultrasound lineup.
Why it matters to buyers: SieClear is a core image-quality feature across Siemens ACUSON ultrasound. Image quality improvements on body imaging are particularly meaningful in patients with complex anatomy or difficult acoustic access.
Why it matters to engineers: SieClear is a software feature running on the ACUSON beamformer. Commissioning and periodic QC include SieClear-mode phantom tests. License status matters on pre-owned ACUSON carts.
