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

Vacancy: Assistant/Associate Professor of Bioelectronics

The Bioelectronics group is offering a tenure-track position at the Assistant or Associate Professor level in the field of biomedical circuits and systems. You will further develop existing research topics, such as mixed-mode and digital circuits and systems for active wearable and implantable medical devices and create new topics, which may include bioelectronic medicine. You will be involved in teaching at the BSc and MSc levels in the TU Delft's Electrical Engineering and Biomedical Engineering programmes and the Leiden-Delft-Erasmus Technical Medicine programme. Collaborative initiatives are strongly encouraged. You are expected to write research proposals for national and international funding organisations.

Prof. dr. Makinwa installed as KNAW member

Prof. Dr. Kofi Makinwa, Professor Electronic Instrumentation and chair of the Micro Electronic department to the faculty of EEMCS, was selected as a new member of The Royal Dutch Academy of Sciences (KNAW) in April. Members of the KNAW, leading scientists from all disciplines, are chosen on their scientific achievements. The new academy members were installed on September 17 in Amsterdam.
