(author), Verweij, M.D. (author), de Jong, N. (author), Pertijs, M.A.P. (author)Intra-cardiac echography (ICE) probes (Fig. 32.2.1) are widely used in electrophysiology for their good procedure guidance and relatively safe application. ASICs are increasingly employed in these miniature probes to enhance signal quality and reduce the number of connections needed in mm-diameter catheters [1]-[5]. 3D visualization in real...conference paper 2022

Zhang, C. (author), Deng, Z.C. (author), Zhang, Y.M. (author), Chen, C. (author)This paper develops an empirical model to predict the static yield stress of 3D printing mortar based on the flowability of paste and excess paste thickness. The components of the mortar are divided into paste and aggregate. The relation between the yield stress of mortar and the yield stress of paste and the excess paste thickness is...conference paper 2021

Chen, C. (author), Chen, Z. (author), Chang, Z.Y. (author), Pertijs, M.A.P. (author)This paper presents a power- and area-efficient 9-channel LNA array for piezoelectric ultrasound transducers to enable real-time 3D imaging with miniature endoscopic and catheter-based probes. In view of the relatively low impedance of piezoelectric transducers, the LNA is implemented as a capacitive feedback voltage amplifier, rather than a...conference paper 2015
