The NYQUIST LIIMIT-It is a sampling phenomenon, which limits the maximum fiequemcy shift measurement to one half of the sampling frequency (PRF).
By its nature, pulse wave Doppler is a sampling system while continuous wave Doppler is not. The nyquist limit is a theoretical maximum frequency that a
If the frequency shift is higher than the Nyquist frequency, aliasing occurs; i.e., the Doppler spectrum is cut off the Nyquist frequency and the remaining frequency shift is recorded on the opposite side of baseline.
The PRF varies inversely with the depth of the sample volume the shallower the location of the sample volume, the higher the PRF and Nyquist frequency. In other words, higher velocities can be recorded without aliasing by pulse wave Doppler if the sample volume is closer to transducer.

Why is an S strain of bacteria able to cause disease in mammals but a R strain is not? The slippery capsule stops the cells of the defence system from capturing and destroying
What are the fruiting bodies present in some fungi? Fruiting bodies are structures made of hyphae that project radially from the superior portion of the peduncle of some fungi.
Ventricular Assist Devices : These come handy when IABP has failed or when prolonged circulatory support is needed. Now Ieft ventricular (LVAD), right ventricular (RVAD) and bive
Q. What is the nitrogen waste in amphibian larvae and in the adult animal? The terrestrial adult excretes urea since amphibian larvae are aquatic they excrete ammonia.
What is a population? The population is a set of individuals of the same species found in a given place in a given time.
Heat Loss Temperature regulation is extremely uneconomical if it depends only on variations in metabolism. Therefore, mechanisms for losing excess heat have been developed by
