Statemed STT-INSIGHT 23R Cheaper And Good Hospital Equipment Ultrasonic B mode 1. Multi-gate Doppler and 3D Spectrum Display Introduction Multi-gate Doppler is a patented Saset technology that offers visualization of the velocity profile in the velocity/depth plane and of the 3D spectrum with the additional axis of axial depth. The result offers never-before-seen information regarding the hemodynamics of vessels, and significantly improves the accuracy of volume flow estimation. Method The method subdivides the axial gate into multiple smaller sub-gates. Spectrum is computed for each subgate, and the resulting velocity distribution may be plotted in the velocity/axial distance axis as a velocity profile. Additionally, the full 3D data, consisting of velocity, time, and depth axes, is displayed. As an example of the clinical significance, the central collapse of the velocity profile after systole is related to the elasticity of the vessel wall. Improved volume flow estimation The Doppler gate is widened to the entirety of the vessel. By assuming radial symmetry, the volume flow can be estimated from the numerous sub-gates. This is an improvement over conventional single-gate Doppler which assumes the velocity distribution is laminar over the entirety of the gate, which is clearly false. We verify the increase in accuracy by flow phantom experiments, using both conventional and multi-gate Doppler to estimate volume flow. 2. Elasticity Imaging in Healthcare Introduction Tissue elasticity offers clinically significant information on tumor and lesion growth, including early state characterization that may greatly assist early diagnosis. We present visualization of tissue elasticity through two methods: 1) Freehand elastography using manual probe compression 2) Sound-Push elastography & shear wave speed estimation using ARFI Freehand elastography Motion tracking of manual compression or breathing induced movement generates a strain image representing the elasticity of the underlying tissue. Saset has one issued patent and our lab in collaboration with Sichuan University has 17 published academic papers and 7 PhD theses. Wave Speed estimation Saset introduces Sound-Push elastography, with two pending patents, which does not require manual compression as it is based on transmitting high energy pulses to acoustically push the tissue. This technique results in more accurate strain images. Moreover, Saset offers shear wave speed estimation which can diagnosis liver fibrosis diseases quantitatively. Figure 4. ARFI image of the edema (the white spot in the right picture) in early Achilles tendon injury Experimental verification and accuracy analysis In our lab, we have verified our Sound-Push elastography using Model 049, CIRS Elasticity QA phantom, with results between 1.25% and 4.44% error using four types of hard/soft lesions. Additionally, we verified shear wave speed estimation using Model 039, CIRS Shear Wave Liver Fibrosis Phantom, with 1.61% to 6.37% error (from 4 to 44.4 kPa Youngs modulus)
