Advancement simplifies laser-based medical imaging

Photoacoustic imaging, a technique for examining living materials through the use of laser light and ultrasonic sound waves, has many potential applications in medicine because of its ability to show everything from organs ...

Two-in-one contrast agent for medical imaging

Magnetic resonance imaging (MRI) visualizes internal body structures, often with the help of contrast agents to enhance sensitivity. A Belgian team of scientists has now developed a bimodal contrast agent suited for two imaging ...

Light and sound gauge the temperature of deep tissues

Measuring a fever is usually pretty simple: place a thermometer under a patient's tongue and get an accurate temperature reading within 30 seconds. But that simplicity does not translate when it comes to measuring the temperatures ...

Adapting technology to image blood vessels in skin disease

Small vessel vasculitis—inflammation of the small blood vessels—appears as a stain of tiny, red dots covering the skin that, depending on the severity, can evolve into painful pustules or ulcers. In some patients, it ...

Laser, sound waves provide live views of organs in action

Biomedical engineers are now able to take a live, holistic look at the inner workings of a small animal with enough resolution to see active organs, flowing blood, circulating melanoma cells and firing neural networks.

Compound boosts contrast of photoacoustic images

An agent for enhancing the contrast of photoacoustic imaging—an emerging imaging modality that involves 'listening' to the sound generated by laser light—has been developed by A*STAR researchers.
