Full-field high-speed laser Doppler imaging system for blood-flow measurements

Theo Lasser

We describe the design and performance of a new full-field high-speed laser Doppler imaging system developed for mapping and monitoring of blood flow in biological tissue. The total imaging time for 256x256 pixels region of interest is 1.2 seconds. An inte ...

High-speed laser Doppler perfusion imaging using an integrating CMOS image sensor

Theo Lasser

This paper describes the design and the performance of a new high-speed laser Doppler imaging system for monitoring blood flow over an area of tissue. The new imager delivers high-resolution flow images (256 x 256 pixels) every 2 to 10 seconds, depending o ...

Guest Editorial: Wavelets in Medical Imaging

Michaël Unser

I. Introduction Wavelets are the result of collective efforts that recognized common threads between ideas and concepts that had been independently developed and investigated by distinct research communities. They provide a unifying framework for decompos ...

Multidimensional, Multistage Wavelet Footprints: A New Tool for Image Segmentation and Feature Extraction in Medical Ultrasound

Michaël Unser, Michael Sühling, Muthuvel Arigovindan

We present a new wavelet-based strategy for autonomous feature extraction and segmentation of cardiac structures in dynamic ultrasound images. Image sequences subjected to a multidimensional (2D plus time) wavelet transform yield a large number of individu ...

Fast Parametric Elastic Image Registration

Michaël Unser

We present an algorithm for fast elastic multidimensional intensity-based image registration with a parametric model of the deformation. It is fully automatic in its default mode of operation. In the case of hard real-world problems, it is capable of accep ...

Distance transformations: fast algorithms and applications to medical image processing

Olivier Cuisenaire

Medical image processing is a demanding domain, both in terms of CPU and memory requirements. The volume of data to be processed is often large (a typical MRI dataset requires 10 MBytes) and many processing tools are only useful to the physician if they ar ...

Measurement of interfacial areas in gas-liquid dispersions by ultrasonic pulse transmission

Urs von Stockar

An ultrasound pulse transmission technique was studied as an alternative means of measuring the specific interfacial area (a) in gas-liq. reactors. Characterization of gas-liq. dispersions using ultrasound can be a very valuable alternative in situations i ...
