Advantage超聲模體提供了一種新的改進(jìn)的雙掃描表面設(shè)計(jì),可輕松適應(yīng)線性,扇形內(nèi)窺鏡探頭和經(jīng)食管(TEE)探頭。 ![]() ![]() ![]() 美國(guó)acertara Advantage超聲模體特點(diǎn): 死區(qū)或環(huán)下(A1和A2) 水平測(cè)量校準(zhǔn)線性(C1和C2) 水平測(cè)量校準(zhǔn)扇區(qū)(C1和C2) 靈敏度/滲透(F) 垂直測(cè)量校準(zhǔn)(B1和B2) 圖像均勻性(無(wú)目標(biāo)區(qū)域) 功能分辨率(F1,F(xiàn)2) 焦點(diǎn)區(qū)(B1,B2或F) 軸向和橫向分辨率(E1,E2,E3) 對(duì)比度,灰度(G1,G2,G3) ![]() The Advantage? Ultrasound Phantom is an easy to use comprehensive means of evaluating ultrasound systems with an effective operating frequency range of 2.25 to 10MHz. The phantom is designed with a combination of monofilament line targets for distance measurements and tissue mimicking target structures of varying sizes and contrast content. Four gray scale targets ranging in contrast from +6 to -3dB are provided to evaluate the system’s displayed dynamic range and gray scale processing performance. The Advantage? Phantom offers a new and improved dual scan surface design to easily accommodate linear, sector, endoscopic probes and transesophageal (TEE) probes. scanning-port-for-tee-probes-phantom-picenoscopic-scan-surface-with-trough-phantom-picstandard-scan-surface-phantom-pic Dead Zone or Ring-Down (A1 & A2) Horizontal Measurement Calibration Linear (C1&C2) Horizontal Measurement Calibration Sector (C1 & C2) Sensitivity/Penetration (F) Vertical Measurement Calibration (B1 & B2) Image Uniformity (target-free areas) Functional Resolution (F1, F2) Focal Zone (B1, B2 or F) Axial & Lateral Resolution (E1, E2, E3) Contrast, Gray Scale (G1, G2, G3)
