High-frame-rate volumetric ultrasound imaging using dedicated arrays and deep learning

High-frame-rate volumetric ultrasound imaging is highly desired to enable novel clinical ultrasound applications. However, realizing high-quality volumetric ultrasound imaging at a high frame rates (>500 Hz) is challenging. Keeping the cable count and data rate of the transducer device at a realistic level without sacrificing image quality to...

Integrated Circuits for 3D High-Frame-Rate Intracardiac Echocardiography Probes

This thesis describes the design of application-specific integrated circuits (ASICs) for high-frame-rate 3D intracardiac echocardiography (ICE) probes. The work follows the whole process from the analysis of the application to the testing of a prototype with all envisioned functionality. It starts with the evaluation of the main challenges posed...

Land time-lapse CSEM: Collecting, modeling and inversion of CSEM data for a steam-injected oil field

Geophysical methods are widely used for hydrocarbon exploration and time-lapse measurements. One method that can be applied in place of or in addition to the routinely used seismic method, is the Controlled-Source ElectroMagnetic (CSEM) method. The work described in this thesis explores various aspects to improve the land CSEM method for...

Perception and cognition of depth of field

A common way to present 3D materials to human observers nowadays is by stereoscopic displaying on 3D TVs or head-mounted displays such as the Oculus Rift. However, not everyone can see three-dimensional solid shape from stereoscopic viewing and the three-dimensional images remain two-dimensional pictures to them rather than solid shapes....

SizeChina: A 3D Anthropometric Survey of the Chinese Head

Problem The design of consumer products that are worn on the head relies on the availability of accurate anthropometric information describing the shape and size of the human head and face. Historical anthropometric studies with univariate data have documented the existence of shape differences between Asian and Western head shapes, but the...
