A research team has developed a bimodal photoacoustic/ ultrasound imaging technology for the human foot. Our body is like a sophisticated network with a myriad of peripheral blood vessels connected ...

Philips has upgraded its smartphone-controlled hand-held ultrasound system, adding pulse wave Doppler support to help clinicians examine real-time blood flow across a range of diagnostic applications.

Both ultrasound for medical imaging and seismology for imaging the Earth's interior measure the propagation of waves through matter. For example, when seismic waves encounter material differences in ...

The use of sound waves for non-invasively visualizing a fetus in the womb, via ultrasound imaging, is widely recognized. By emitting high-frequency sound waves into the body and converting their echo ...
