A small-aperture, prototype ultrasonic imaging system, typical of the size necessary to be embedded in a catheter, was developed to evaluate the feasibility of intravascular ultrasonic imaging catheters (UICs). The evaluation included in vitro imaging of postmortem samples of human femoral and iliac arteries with the UIC prototype and a high-resolution magnetic resonance (MR) proton imager. Excellent correlations between results from the UIC images, MR images, and tissue specimens were demonstrated. Although the current prototype is too large to be useful in examination of smaller vessels such as coronary arteries, the signal-to-noise ratio and resolution obtained indicate that imaging with intravascular UICs is feasible and may have significant diagnostic value.
开发了一种小孔径的原型超声成像系统，其尺寸是嵌入导管所需的典型尺寸，以评估血管内超声成像导管（UIC）的可行性。评估包括使用UIC原型和高分辨率磁共振（MR）质子成像仪对人股动脉和髂动脉的死后样本进行体外成像。结果表明，UIC图像、MR图像和组织标本之间具有极好的相关性。虽然目前的原型太大，无法用于检查诸如冠状动脉等较小血管，但所获得的信噪比和分辨率表明，使用血管内UIC进行成像具有可行性，并且可能具有重要的诊断价值。
