This paper is the result of a collaboration on intravascular ultrasound imaging between the Ultrasound ASICs group at the Electronic Instrumentation Lab, the Thoraxcenter at Erasmus MC, and the Laboratory of Acoustical Wavefield Imaging at the Faculty of Applied Sciences, Delft University of Technology.
Forward-looking intravascular ultrasound (FL-IVUS) holds rich potential for guidance of complex vascular interventions, such as recanalization of coronary chronic total occlusions. The realization of FL-IVUS devices is fraught with technical challenges, as a high-resolution volumetric image needs to be created from a small (< 1.5 mm) aperture with scant space for cabling and electronics. In this issue of the Transactions, we present an innovative concept for an FL-IVUS matrix array, consisting of 16 transmit (yellow) and 64 receive elements (red), addressed by only four cables. A dedicated front-end ASIC performs element addressing and received signal amplification. The realized configuration produces a narrow pulse-echo beam profile with sidelobes below −20 dB. 3-D synthetic aperture imaging (bottom) at a volume rate of 100 Hz is feasible.
Details on the ASIC, which was designed at the Electronic Instrumentation Lab by Mingliang Tan, Chao Chen, Zhao Chen and Michiel Pertijs, can be found in

Microelectronics at work for sustainable healthcare
Institutions in the Medical Delta (a consortium consisting of TU Delft, Erasmus MC, LUMC, Leiden University and Erasmus University Rotterdam) are starting a broad and unique scientific programme in the field of technological research into innovative solutions for sustainable healthcare. This will involve an investment of five million euros over the next five years.
Health Prototype Grant for Virgilio Valente
Virgilio (Vivo) Valente received a Health Prototype Grant of €10K from the Delft Health Initiative for his proposal in the domains of Lab-on-CMOS and Organs-on-a-Chip.
Image formation for future radio telescopes
Radio astronomy is an interesting application area for array signal processing. We developed a new image formation tool called PRIFIRA, inspired by Sparse Bayesian Learning.
