It was estimated that annual cost of measurable medical errors was higher than $17 billion in 2008. Phantoms are objects manufactured using a tissue mimicking material (TMM) and largely used to test protocols and mimic clinical environment for medical training. TMM should reproduce at least one biological property to allow the association with clinical situation. The gel made by the copolymer styrene-ethylene/butylene-styrene...
Photoacoustic imaging is a hybrid imaging modality where ultrasound signal is generated when laser pulses are absorbed by tissue. Tissue-mimicking phantom is a useful tool to characterizing new imaging methods. However, there is still a lack of development of phantoms applied to hybrid modalities such as photoacoustics. SEBS gel is a translucent material and present acoustic and elastic properties...
Magnetomotive ultrasound (MMUS) imaging indirectly enables visualization of magnetic nanoparticles (MNPs) with ultrasound. An external time varying magnetic field displaces MNPs and thus their closest surrounding, the induced displacement is tracked in the US data and color-coded on B-mode images. However, images are currently processed offline, which is time consuming and precludes clinical use of...
Enabling detection of nanoparticles with ultrasound can open new application avenues for the ultrasound technique. Magnetomotive ultrasound (MMUS) is a technique under development which indirectly visualizes magnetic nanoparticles. In MMUS, an external time-varying magnetic field acts to displace the nanoparticles, and thus their closest surrounding. This induced displacement is subsequently detected...
Phantoms are important tools for image quality control and medical training. Many phantom materials have been proposed for ultrasound; most of them use water as the solvent, but these materials have disadvantages such as dehydration and low temporal stability if not properly stored. To overcome these difficulties, copolymer-in-oil gel was proposed as an inert and stable material; however, speed of...
Phantoms are important tools for image quality control of current and new imaging modalities and medical training procedures. Many phantom materials have been proposed; most of them use water as solvent, but these materials have disadvantages such as dehydration and low temporal stability. In order to overcome these difficulties, copolymer-in-oil gel was proposed as an inert and stable material; however,...
Photoacoustic imaging is a hybrid imaging modality, where ultrasound waves are generated from the interaction between light and biological tissue. Therefore, the image contrast is based on the optical absorption properties of tissues. A useful approach for studying photoacoustic imaging methods is through tissue-mimicking phantom experiments. Water-based materials are commonly used in phantoms for...
