| − | + | *'''Physiological Systems Modeling''' – Physiological processes can often be modeled mathematically. An organism's environment (or the output from another body system) can be viewed as a signal, x(t). The physiological system being modeled, h(t), will convert this signal into output, y(t). For example, the blood clotting mechanism can be illustrated as a system [[Video Tutorial on How to Cascade Transformations of the Independent Variable|cascade]]: <br>x(t) = the amount of protein released by damaged endothelium (skin) cells<br>h1(t) = amplifying system <br>w1(t) = the amount of clotting factor VII<br>h2(t) = amplifying system<br>w2(t) = the amount of factor XI converted to XIa<br>and so forth until the final output...<br>y(t) = amount of cross-linked fibrin (that makes the blood clot)<br>Would you consider this system [[Memoryless system question ECE301S11|memoryless?]] [[Causal system question ECE301S11|Causal?]] | |
| − | * | + | *'''Image and Image Processing''' – X-ray, ultrasound, MRI (magnetic resonance imaging), and CT (computerized tomography) scans all convert analog physical signals to discrete computer signals. Systems (maybe even [[Fourier_Transform_Video |Fourier]]/Laplace/[[Compute z-transform u n ECE301S11|Z transforms]] from [[2011 Spring ECE 301 Boutin|ECE301]]!) are utilized to convert, filter, and combine these signals and produce the images used in diagnostics. |

| − | + | *'''Bioinformatics''' – Gene sequencing requires techniques to translate DNA from chromosomes to digitally recordable information. Think of each nucleic acid as n = 0, 1, 2, ... for the discrete signal x[n] of the entire DNA sequence. (Maybe x[n] = 1, 2, 3, and 4 corresponding to adenine, guanine, cytosine, and thymine.) Furthermore, this signal must be broken into distinct genes and decoded. These genes can be matched to their potential phenotypes (physical traits/functions) using databases of sequences. | |
| − | + | *'''Proteomics''' – A proteome is the set of proteins produced by a species, similar to a set of genes in a genome. The study of proteomes is important in understanding cellular processes, infection, and patterns related to disease. In proteomics, engineers must develop hardware that can measure protein levels rapidly and accurately. In this case, the protein levels can be thought of as a CT signal, sampled and stored as a DT signal. Think about what we have learned about [[2011 Spring ECE 301 Bouton Notes|sampling and conversion between CT/DT signals]]. Filters are also used to sort the main trend of the signal from the noise (common in biological systems). | |
| − | + | *'''Wireless and Mobile Technologies''' – Just as phones and computers have gone wireless, now medical equipment, sensors, and surgical devices are going wireless.

ECE 301: Applications in Biomedical Engineering
Examples of Signals and Systems in Biomedical Engineering:
- Physiological Systems Modeling – Physiological processes can often be modeled mathematically. An organism's environment (or the output from another body system) can be viewed as a signal, x(t). The physiological system being modeled, h(t), will convert this signal into output, y(t). For example, the blood clotting mechanism can be illustrated as a system cascade:
x(t) = the amount of protein released by damaged endothelium (skin) cells
h1(t) = amplifying system
w1(t) = the amount of clotting factor VII
h2(t) = amplifying system
w2(t) = the amount of factor XI converted to XIa
and so forth until the final output...
y(t) = amount of cross-linked fibrin (that makes the blood clot)
Would you consider this system memoryless? Causal?
- Image and Image Processing – X-ray, ultrasound, MRI (magnetic resonance imaging), and CT (computerized tomography) scans all convert analog physical signals to discrete computer signals. Systems (maybe even Fourier/Laplace/Z transforms from ECE301!) are utilized to convert, filter, and combine these signals and produce the images used in diagnostics.
- Bioinformatics – Gene sequencing requires techniques to translate DNA from chromosomes to digitally recordable information. Think of each nucleic acid as n = 0, 1, 2, ... for the discrete signal x[n] of the entire DNA sequence. (Maybe x[n] = 1, 2, 3, and 4 corresponding to adenine, guanine, cytosine, and thymine.) Furthermore, this signal must be broken into distinct genes and decoded. These genes can be matched to their potential phenotypes (physical traits/functions) using databases of sequences.
- Proteomics – A proteome is the set of proteins produced by a species, similar to a set of genes in a genome. The study of proteomes is important in understanding cellular processes, infection, and patterns related to disease. In proteomics, engineers must develop hardware that can measure protein levels rapidly and accurately. In this case, the protein levels can be thought of as a CT signal, sampled and stored as a DT signal. Think about what we have learned about sampling and conversion between CT/DT signals. Filters are also used to sort the main trend of the signal from the noise (common in biological systems).
- Wireless and Mobile Technologies – Just as phones and computers have gone wireless, now medical equipment, sensors, and surgical devices are going wireless. These critical signals must be properly transmitted, which means the use of sampling, signal carriers, CT/DT converters, etc. Athena GTX, a company described in the Biomedical Industry section below, focuses on this exact subject.
- BioSIGNALS – The electrical signals produced by the body are extremely useful in diagnostics:
Electrocardiogram (ECG) – used to measure the electrical activity of the heart and diagnose conditions including blockages and arrhythmias. For more detailed information on diagnosis with ECGs, check out this website: http://www.bem.fi/book/19/19.htm
Electromyogram (EMG) – used to measure the electrical activity of muscles and nerves to diagnose conditions including carpal tunnel syndrome and sciatica. One technique, called targeted muscle reinnervation (TMR), uses these signals to allow amputees to control mechanical limbs with their natural nerve signals. Purdue professor Pedro Irazoqui, research link below, is involved in this research with DARPA and Northwestern University.
Electroencephalogram (EEG) – used to measure the electrical activity of the brain to diagnose conditions including epilepsy and comas. Biomedical research attempts to use these signals to allow people with paralysis to control a computer.
All of these signals require filtering of background noise and, often times, conversion from continuous time (CT) to discrete time (DT).
