Hi, I am a biomedical imaging and visualization researcher who investigates how computational methods can accelerate biological and medical research.
Welcome
Back!
This course is different!
No Project!
Hands-on Knowledge + Research
Be a Biomedical
3rd oldest Hospital in the US
$1+ billion research program
largest in the world
6th best Hospital in the US
5th best place to work in MA (2017)
$630+ million research program
2nd largest in the world
13th best Hospital in the US
also a good place to work :)
are part of
New imaging complex at Assembly Row
~1000 Biotech companies in Boston!
All universities have some biomedical research going on!
This course prepares
for a career in biomedical research and life sciences!

Continuous Signal
Analog
Infinite Accuracy and Infinite Measurements
Electrical Signals
Mechanical Signals
Hydraulic Signals
Optical Signals
Chemical Signals
Electrical Potentials/Activity like ECG, EEG..
Vibrations such as Mechanomyogram (MMG)
pH measurement, urinalaysis (UA), blood glucose, electrolyte levels, cholesterol..
blood vessel wall shear stress
some imaging methods (X-ray, NIRS..)
blood pressure?
Accustical Signals
blood pressure.

Sampling
Analog
Sampling Rate
Samples per second [1/s]
Hertz [Hz]
Analog Signal
2 Samples per second
0

time [s]
6 Samples per second
10 Samples per second
6 Hz
10 Hz
2 Hz
Aliasing
Original Signal
Sampled Points
Reconstructed Signal
Sampling Rate too low
A higher sampling rate is better
?
2 Floats
6 Floats
10 Floats
It's a trade-off!
Nyquist-Shannon Theorem
sampling frequency > 2x signal frequency
guarantees perfect reconstruction
What does that mean? And how do we get the signal frequency?
