This produces large quantities of harmonic frequencies in the reflected ultrasound signal that can be detected by ultrasound transducers and machines enabled with suitable contrast-specific software.

including the developments in the digital signal processing (DSP)as well as the micro electronics. These changes made the development of compact ultrasound machines possible, in size, price ...

Apparently a Flanagan Neurophone uses ultrasound in some manner to transmit ... The only challenge might be tuning the thing with a signal generator or audio feed. So how about it, any one have ...

A paper on the work, "Tailored Ultrasound Propagation in Microscale ... demultiplexer (a device that separates one acoustic signal into multiple output signals). The work paves the way for ...

Ultrasound close ultrasoundSound with a frequency ... the depth of a sea floor bed or the position of shoals of fish. A signal is sent out from a transmitter and the reflected signal (the echo ...

The proposed approach uses an ultrasound piezoelectric transducer ... A function generator is used to send a sinusoidal electrical signal to the transducer. In their study, the researchers ...

Lesser grades of MR signal abnormality at baseline were associated with better clinical status at 12 month follow up. Conclusions: US and MRI show only moderate correlation with clinical assessment of ...
