美國(guó)acertara Advantage超聲模體詳細(xì)介紹：
Advantage超聲模體是一種易于使用的評(píng)估超聲系統(tǒng)的綜合手段，其有效工作頻率范圍為2.25至10MHz。 Advantage超聲模體的設(shè)計(jì)結(jié)合了用于距離測(cè)量的單絲線(xiàn)目標(biāo)和不同尺寸和對(duì)比度內(nèi)容的組織模擬目標(biāo)結(jié)構(gòu)。 提供四個(gè)灰度目標(biāo)，其范圍與+6至-3dB相反，用于評(píng)估系統(tǒng)顯示的動(dòng)態(tài)范圍和灰度級(jí)處理性能。
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(xiàn)性，扇形內(nèi)窺鏡探頭和經(jīng)食管（TEE）探頭。

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.
