Photoacoustic

Ph. D., and including Gregory Lanza, M.D., and Samuel Wickline, M.D., both members of the Siteman Center of Cancer Nanotechnology Excellence, has developed "soft" gold nanoparticles that accumulate in sentinel lymph nodes and that are visible using a technique known as photoacoustic imaging. ❋ Unknown (2010)

A promising new technique called photoacoustic tomography (PAT) can overcome these problems. ❋ Unknown (2010)

On the hint: Alexander Graham Bell discovered the photoacoustic effect, turning it into, what else, a telephone. ❋ EliRabett (2010)

In the original photoacoustic imaging technique, the image resolution was about the same as that of ultrasound. ❋ Chris Lee (2011)

Lihong Wang from Washington University presented some fantastic results on photoacoustic imaging in a plenary talk at the conference, bedazzling the audience with beautiful image after beautiful image. ❋ Chris Lee (2011)

So, instead of flooding the tissue with light and getting image resolution on the order of the acoustic wavelength, you can focus the light and use the photoacoustic signal as a contrast mechanism for distinguishing absorption at the scale of the wavelength of light. ❋ Chris Lee (2011)

What Wang has shown is that, with a bit of imagination, a flexible attitude, and a huge amount of work, photoacoustic imaging can be made into an all-singing, all-dancing imaging modality. ❋ Chris Lee (2011)

By putting a photoacoustic imaging system into an endoscope, Wang has shown that you can get up close and personal with various body parts. ❋ Chris Lee (2011)

Still, photoacoustic images of melanomas are fuzzy and vague around the edges. ❋ Unknown (2010)

Subcutaneous mouse melanomas barely visible to the unaided eye show up clearly in the photoacoustic images, their subterranean peninsulas and islands of malignancy starkly revealed. ❋ Unknown (2010)

For photoacoustic imaging, Xia's team tunes the nanocages to absorb strongly at 780 nanometers, a wavelength that falls within a narrow window of tissue transparency in the near-infrared. ❋ Unknown (2010)

With the contrast agent, the photoacoustic signal from the melanoma was 36 percent stronger. ❋ Unknown (2010)
