Imaging with second-harmonic radiation probes in living tissue

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Thomas Jean Victor Marie Lanvin

We demonstrate that second-harmonic radiation imaging probes are efficient biomarkers for imaging in living tissue. We show that 100 nm and 300 nm BaTiO3 nanoparticles used as contrast markers could be detected through 50 mu m and 120 mu m of mouse tail ti ...

Automatic quality assessment in structural brain magnetic resonance imaging

Jean-Philippe Thiran, Reto Meuli

MRI has evolved into an important diagnostic technique in medical imaging. However, reliability of the derived diagnosis can be degraded by artifacts, which challenge both radiologists and automatic computer-aided diagnosis. This work proposes a fully-auto ...

A bulk modulus dependent linear model for acoustical imaging

Michaël Unser, Thierry Blu

Modeling the acoustical process of soft biological tissue imaging and understanding the consequences of the approximations required by. such modeling are key steps for accurately simulating ultrasonic scanning as well as estimating the scattering coefficie ...

Method for automatic artifacts detection in human MR images

A method for detecting, in single time-point, in-vivo imaging data related to artifacts in the imaging of objects, includes acquiring at least one in-vivo image with imaging apparatus. A background image corresponds to imaged air of the in-vivo image. The ...

Discriminative Cue Integration for Medical Image Annotation

Barbara Caputo, Tatiana Tommasi

Automatic annotation of medical images is an increasingly important tool for physicians in their daily activity. Hospitals produce nowadays an increasing amount of data. Manual annotation is very costly and prone to human mistakes. This paper proposes a mu ...

A 130nm CMOS Single Photon Avalanche Diode

Edoardo Charbon, Cristiano Niclass, Marek Gersbach

The first implementation of a single photon avalanche diode (SPAD) is reported in 130nm CMOS technology. The SPAD is fabricated as p+/nwell junction with octagonal shape. Premature edge breakdown is prevented through a guard ring of p-well around the p+ an ...

Combined laser Doppler and laser speckle imaging for real- time blood blow measurements

Theo Lasser

Laser Doppler (LDI) and laser speckle imaging (LSI) are two optical non-invasive techniques that are used to obtain 2D maps of blood flow in biological tissues. Each of these techniques has some benefits and drawbacks for measuring the blood flow. LSI is a ...

From volumetric graphical objects to surface registration

Eduardo Solanas Vilar

Relatively recent developments in medical imaging allow the anatomical and functional noninvasive study of internal organs of the body. One of the most complex and interesting organs in our body is the brain. Many efforts are being carried out to try to un ...

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 ...
