开发了一种小孔径原型超声成像系统，其典型尺寸为嵌入导管所需的尺寸，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。UIC图像、MR图像和组织标本的结果之间具有良好的相关性。虽然目前的原型是太大，是有用的，在检查较小的血管，如冠状动脉，信噪比和分辨率表明，血管内UIC成像是可行的，并可能有显着的诊断价值。
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.
