Analysis based on the mathematical function first formulated by Jean-Baptiste-Joseph Fourier in 1807. The function, known as the Fourier transform, describes the sinusoidal pattern of any fluctuating pattern in the physical world in terms of its amplitude and its phase. It has broad applications in biomedicine, e.g., analysis of the x-ray crystallography data pivotal in identifying the double helical nature of DNA and in analysis of other molecules, including viruses, and the modified back-projection algorithm universally used in computerized tomography imaging, etc. (From Segen, The Dictionary of Modern Medicine, 1992)

Spatiotemporal image correlation using high-definition flow: a new method for assessing ovarian vascularization. (8/151)

OBJECTIVE: The purpose of this study was to describe a new method for assessing ovarian vascularization using spatiotemporal image correlation (STIC)-high-definition flow (HDF). METHODS: Thirty healthy premenopausal fertile women were assessed in the follicular part of the menstrual cycle by transvaginal sonography. A 4-dimensional STIC-HDF volume was obtained from the nondominant ovary to assess 3-dimensional (3D) vascular indices (vascularization index [VI] and flow index [FI]) during one cardiac cycle in each women. Using 1-cm(3) spherical sampling, we calculated the VI and FI from the most vascularized part of the ovarian stroma at two different moments of the cardiac cycle (systole and diastole). System settings were kept constant for all of the patients (pulse repetition frequency, 0.9 kHz; gain, 0.8; and depth, 40 mm). We calculated the VI and FI ratios between systole and diastole. RESULTS: The mean VI during systole (11.485%; SD, 6.7%) was significantly higher than during diastole (8.653%; SD, 5.6%; P < .0001). The mean FI values during systole (47.799 [unitless]; SD, 5.8) and diastole (47.791; SD, 6.0) were nearly identical (P = .993). The VI ratio was 1.35 (95% confidence interval, 1.28-1.42), which means that the mean VI was 35% higher during systole compared to diastole, whereas the FI during systole and diastole remained constant (FI ratio, 1.00; 95% confidence interval, 0.96-1.04). There was a high correlation between VI values during systole and diastole (r(2) = 0.94), whereas this correlation was weaker for the FI (r(2) = 0.45). CONCLUSIONS: The STIC-HDF method allows assessment of 3D vascular indices throughout the cardiac cycle. Vascularization index calculation is affected by the moment of the cardiac cycle during which the measurement is taken. However, it seems that FI calculation is not affected by the cardiac cycle in the normal nondominant ovary.  (+info)

Wavelet analysis is not a medical term, but rather a mathematical technique that has been applied in various fields, including medicine. It is a method used to analyze data signals or functions by decomposing them into different frequency components and time-shifted versions of the original signal. This allows for the examination of how the frequency content of a signal changes over time.

In the medical field, wavelet analysis has been applied in various ways such as:

1. Image processing: Wavelet analysis can be used to enhance medical images like MRI and CT scans by reducing noise while preserving important details.
2. Signal processing: It can be used to analyze physiological signals like ECG, EEG, and blood pressure waves to detect anomalies or patterns that may indicate diseases or conditions.
3. Data compression: Wavelet analysis is employed in the compression of large medical datasets, such as those generated by functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) scans.
4. Biomedical engineering: Wavelet analysis can be used to model and simulate complex biological systems, like the cardiovascular system or the nervous system.

In summary, wavelet analysis is a mathematical technique that has been applied in various medical fields for image processing, signal processing, data compression, and biomedical engineering purposes.

Triacetin is not a medical term, but it is a chemical compound with the formula C9H14O6. It is also known as glycerol triacetate and is an ester formed from glycerin and acetic acid. Triacetin is used in various applications including as a food additive, plasticizer, solvent, and in the manufacture of explosives.

In the medical field, triacetin has been studied for its potential therapeutic uses, such as a topical agent to enhance the penetration of drugs through the skin, and as an excipient in pharmaceutical formulations. However, it is not commonly used as a medication or treatment.

Congenital nystagmus is a type of involuntary eye movement that is present at birth or develops within the first few months of life. It is characterized by rhythmic oscillations or repetitive, rapid movements of the eyes in either horizontal, vertical, or rotatory directions. These movements can impair vision and may be associated with other ocular conditions such as albinism, congenital cataracts, or optic nerve hypoplasia. The exact cause of congenital nystagmus is not fully understood, but it is believed to result from abnormal development or dysfunction in the areas of the brain that control eye movements. In some cases, congenital nystagmus may be inherited as a genetic trait. Treatment options for congenital nystagmus include corrective lenses, prism glasses, surgery, and vision therapy, depending on the underlying cause and severity of the condition.

I'm sorry for any confusion, but "Mathematical Computing" is not a recognized medical term. Mathematical computing is a branch of computer science that focuses on the development and analysis of algorithms and computational methods for solving mathematical problems. It involves the use of computers to perform mathematical calculations and simulations, and it includes various subfields such as numerical analysis, symbolic computation, and computational geometry. If you have any questions about a medical term or concept, I would be happy to help with that instead!

Computer-assisted signal processing is a medical term that refers to the use of computer algorithms and software to analyze, interpret, and extract meaningful information from biological signals. These signals can include physiological data such as electrocardiogram (ECG) waves, electromyography (EMG) signals, electroencephalography (EEG) readings, or medical images.

The goal of computer-assisted signal processing is to automate the analysis of these complex signals and extract relevant features that can be used for diagnostic, monitoring, or therapeutic purposes. This process typically involves several steps, including:

1. Signal acquisition: Collecting raw data from sensors or medical devices.
2. Preprocessing: Cleaning and filtering the data to remove noise and artifacts.
3. Feature extraction: Identifying and quantifying relevant features in the signal, such as peaks, troughs, or patterns.
4. Analysis: Applying statistical or machine learning algorithms to interpret the extracted features and make predictions about the underlying physiological state.
5. Visualization: Presenting the results in a clear and intuitive way for clinicians to review and use.

Computer-assisted signal processing has numerous applications in healthcare, including:

* Diagnosing and monitoring cardiac arrhythmias or other heart conditions using ECG signals.
* Assessing muscle activity and function using EMG signals.
* Monitoring brain activity and diagnosing neurological disorders using EEG readings.
* Analyzing medical images to detect abnormalities, such as tumors or fractures.

Overall, computer-assisted signal processing is a powerful tool for improving the accuracy and efficiency of medical diagnosis and monitoring, enabling clinicians to make more informed decisions about patient care.

I'm sorry for any confusion, but Fourier Analysis is not a medical term. It is a mathematical concept used in various scientific fields, including physics, engineering, and signal processing.

Fourier Analysis is a method to decompose functions into sinusoidal components (sines and cosines) of different frequencies. This allows for the representation of a function or a signal as a sum of these frequency components. It's particularly useful in analyzing periodic functions, understanding signals, and solving partial differential equations.

If you have any medical terms you would like me to define, please let me know!

In the context of medicine, "periodicity" refers to the occurrence of events or phenomena at regular intervals or cycles. This term is often used in reference to recurring symptoms or diseases that have a pattern of appearing and disappearing over time. For example, some medical conditions like menstrual cycles, sleep-wake disorders, and certain infectious diseases exhibit periodicity. It's important to note that the duration and frequency of these cycles can vary depending on the specific condition or individual.

An algorithm is not a medical term, but rather a concept from computer science and mathematics. In the context of medicine, algorithms are often used to describe step-by-step procedures for diagnosing or managing medical conditions. These procedures typically involve a series of rules or decision points that help healthcare professionals make informed decisions about patient care.

For example, an algorithm for diagnosing a particular type of heart disease might involve taking a patient's medical history, performing a physical exam, ordering certain diagnostic tests, and interpreting the results in a specific way. By following this algorithm, healthcare professionals can ensure that they are using a consistent and evidence-based approach to making a diagnosis.

Algorithms can also be used to guide treatment decisions. For instance, an algorithm for managing diabetes might involve setting target blood sugar levels, recommending certain medications or lifestyle changes based on the patient's individual needs, and monitoring the patient's response to treatment over time.

Overall, algorithms are valuable tools in medicine because they help standardize clinical decision-making and ensure that patients receive high-quality care based on the latest scientific evidence.
