A Pitch-Matched High-Frame-Rate Ultrasound Imaging ASIC for Catheter-Based 3-D Probes

This article presents an application-specific integrated circuit (ASIC) for catheter-based 3-D ultrasound imaging probes. The pitch-matched design implements a comprehensive architecture with high-voltage (HV) transmitters, analog front ends, hybrid beamforming analog-To-digital converters (ADCs), and data transmission to the imaging system....

A Pitch-Matched Transceiver ASIC With Shared Hybrid Beamforming ADC for High-Frame-Rate 3-D Intracardiac Echocardiography

In this article, an application-specific integrated circuit (ASIC) for 3-D, high-frame-rate ultrasound imaging probes is presented. The design is the first to combine element-level, high-voltage (HV) transmitters and analog front-ends, subarray beamforming, and in-probe digitization in a scalable fashion for catheter-based probes. The...

Intracardiac Echocardiography for Transvenous Lead Extractions: Evaluating its Utility in a Vascular Phantom Model

Transvenous lead extractions (TLEs) are minimally invasive procedures in which pacing or implantable cardioverter defibrillator leads are extracted under guidance of 2D X-ray fluoroscopy. Despite the fact that fluoroscopy is currently the gold standard for TLEs, it has several limitations in terms of visualization of anatomical structures, areas...
