Shift-Invariant DWT-Based Ultrasound
2010/1/6
An approach to computing estimates of the
ultrasound pulse spectrum from echo-ultrasound RF sequences,
measured from biological tissues, is proposed. It
is computed by a “projection” algorithm base...
Blind Deconvolution of Ultrasound Sequences Using Nonparametric Local Polynomial Estimates of the Pulse
Blind deconvolution pulse estimation ultrasound
2010/1/6
The problem of reconstructing the reflectivity of a

the echo ultrasound signals. It is shown that the quality of the
reconstruction ...
A Sensitive Reflection-type Pulse Oximeter Using a Gated Avalanche Photodiode
reflection-type pulse oximeter avalanche photodiode lock-in light detection
2009/6/9
We propose a reflection-type pulse oximeter that employs two pairs of a light-emitting diode (LED) and a gated avalanche photodiode (APD). One LED radiates a red line with an emission wavelength of 63...
