to be featured on the cover of the October 2018 issue.

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

Micro electronics colloquium, Thursday March 28, 15.30 EEMCS Restaurantzaal

The XG- “Next Generation Sensing and Communication” research theme is proud to announce a colloquium devoted to the design and development of advanced data converters based on conventional (delta-sigma) as well as unconventional (built-in signal-processing) techniques. The main application of such data converters is in the transceivers, where they enable the reception of multi-channel and multi-standard signals. We are very honoured, to have two leading scientist presenting their work - namely; Prof. Nan Sun , University of Texas and Muhammed Bolatkale, NXP/TU Delft

Vasiliki Giagka appointed associate editor for Bioelectronic Medicine

Vasiliki Giagka, assistant professor at the Bioelectronics Group at Delft University of Technology, has been invited to the editorial board of Bioelectronic Medicine. The journal asked Giagka for her expertise in fabrication microsystem integration and packaging for neural implants. With her appointment, Giagka is currently one of the youngest associate editors working for the journal.
