Appendix A  Technical Description 
A - 14  Instructions for Use 
Advanced SieClear Spatial Compounding Option 
  2D image optimization technique for enhanced viewing of tissue differences by detection of 
subtle lesions and enhanced tissue differentiation 
  Works with Tissue Contrast Enhancement (TCE) to provide detail in complex masses 
Advanced SieClear Spatial Compounding with Color Option 
  Requires the Advanced SieClear Spatial Compounding (ASSC) option 
  Supports ASSC for 2D images when Color is activated 
Dynamic TCE Tissue Contrast Enhancement Option 
  Reduces speckle and enhances contrast to provide a realistic tissue presentation and 
patient-specific processing that adapts to differences in tissue 
Clarify Vascular Enhancement (Clarify VE) Technology Option 
  Available in combination with 2D-mode, the 2D-mode image in Doppler, SieClear 
compounding, and THI 
  Clarify vascular enhancement technology (Clarify VE) is an optional feature that can 
decrease artifacts in the 2D-mode image, resulting in an improved view of anatomical 
structures. Decreased artifacts can enhance definition of both tissue and vessel walls by 
increasing contrast resolution and improving boundary detection. Clarify VE uses flow 
information to eliminate noise and reverberation from vessels. 
  Compatible with the Advanced SieClear Spatial Compounding (ASSC) option 
Custom Tissue Imaging Option 
  Optimizes the 2D image by adjusting the speed of sound.
