This paper provides biological illustrations of the applicability and mode of use of intravascular and perivascular absolute induction angiometers. Artifacts and limitations of the method as well as experimental precautions and calibration procedures are discussed. Tracing are presented to illustrate the capabilities of the method in recording pulsatile diameter changes in veins and arteries and to demonstrate its applicability to moving blood vessels as exemplified by the coronary arteries. Both intravascular and perivascular angiometry can detect diameter changes of a few micra in a vessel 1 cm in diameter. The intravascular angiometer is a resilient loop of fine bifilar wire which can be introduced into the blood vessel percutaneously via an angiographic catheter. A perivascular angiometer is an easily deformable loop made of a soft fine wire pair which is draped around a blood vessel and can thus be chronically implanted.
本文提供了血管内和血管周围绝对感应血管直径测量仪的适用性及使用方式的生物学说明。讨论了该方法的伪像和局限性以及实验预防措施和校准程序。通过示例展示了该方法记录静脉和动脉搏动性直径变化的能力，并证明了其对如冠状动脉等移动血管的适用性。血管内和血管周围血管直径测量法均可检测直径为1厘米的血管中几微米的直径变化。血管内血管直径测量仪是由细双股线制成的弹性环，可通过血管造影导管经皮引入血管。血管周围血管直径测量仪是由柔软的细导线对制成的易于变形的环，环绕在血管周围，因此可以长期植入。
