Intravascular ultrasound allows physicians to see inside the coronary arteries. Longitudinal and cross-sectional images facilitate accurate assessment of plaque morphology, vessel size and lesion length enabling you to deliver precise PCI.

2022年8月13日 · 血管内超声（Intravascular ultrasound，IVUS）是一种血管内的成像方式，可用于各类介入学科，以表征病变形态、量化斑块负荷、指导器械尺寸选择、评估器械植入以及识别并发症。

In this review, we aim to extensively examine the recent advances in ultrasound transducers for IVUS imaging applications. Firstly, a fundamental review of IVUS imaging principle, evaluation parameters and IVUS catheters are presented. Then, different types of ultrasound transducers for IVUS imaging are summarized.

2022年7月12日 · IVUS is a minimally invasive procedure involving tiny instruments and sophisticated technology for evaluations that are gentler on your body. What is intravascular ultrasound? Intravascular ultrasound (IVUS) uses sound waves to assess soft tissue. Tiny instruments capture real-time images from inside your blood vessels.

2023年6月9日 · All-optical IVUS (AO-IVUS) provides a promising solution for simultaneous high penetration depth and high imaging resolution. This is achieved through substantial improvement of frequency response bandwidth in both the excitation …

2021年6月5日 · Intravascular ultrasound (IVUS) is a valuable imaging modality for the diagnosis of atherosclerosis. It provides useful clinical information, such as lumen size, vessel wall thickness, and plaque composition, by providing a cross-sectional vascular image.

Intravascular ultrasound (IVUS) uses a transducer or probe to generate sound waves and produce images of blood vessels. When used to evaluate the coronary arteries, IVUS can show the entire artery wall and provide important information about the amount and type of plaque buildup, which can help determine if you are at risk for heart attack.

2024年9月17日 · IVUS uses well-known sonar techniques to generate intravascular images. The catheter probe consists of a piezoelectric transducer that utilizes the converse piezoelectric effect to transform an electric input into pulses of ultrasound at high frequencies, typically 20-60 MHz.

How does IVUS work? well-known sonar techniques to generate intravascular images. The catheter probe consists of a piezoelectric transducer that utilizes the converse piezoelectric efect to transform an electric input into

2023年9月20日 · In this work, the first known IVUS probe that employs a backing-layer-shared dual-frequency structure and a single coaxial cable is introduced, featuring a small thickness and easy interconnection procedure. The dual-frequency transducer is designed to have center frequencies of 30 MHz and 80 MHz, and both have an aperture size of 0.5 mm × 0.5 mm.
