Convolution Properties II01:17

Convolution Properties II

587
The important convolution properties include width, area, differentiation, and integration properties.
The width property indicates that if the durations of input signals are T1 and T2, then the width of the output response equals the sum of both durations, irrespective of the shapes of the two functions. For instance, convolving two rectangular pulses with durations of 2 seconds and 1 second results in a function with a width of 3 seconds.
The area property asserts that the area under the...

Protein Networks02:26

Protein Networks

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Sensory Modalities01:15

Sensory Modalities

3.9K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Network Covalent Solids02:18

Network Covalent Solids

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

    Area of Science:

    • Medical Imaging
    • Artificial Intelligence
    • Radiology

    Background:

    • Splenomegaly, or enlarged spleen, is a key biomarker for liver and spleen diseases.
    • Automated spleen segmentation in MRI is crucial for efficient quantification but faces challenges like anatomical variations and limited data.
    • Existing methods struggle with multi-modal MRI intensity variations and diverse splenomegaly presentations.

    Purpose of the Study:

    • To develop an automated deep learning method for accurate splenomegaly segmentation in multi-modal MRI.
    • To address challenges in spleen segmentation, including anatomical variability and limited labeled datasets.
    • To evaluate the proposed method against traditional and deep learning-based segmentation techniques.

    Main Methods:

    • Proposed the Splenomegaly Segmentation Network (SS-Net), a deep convolutional neural network (DCNN) incorporating large convolutional kernels.
    • Utilized conditional generative adversarial networks for end-to-end segmentation performance enhancement.
    • Trained and evaluated SS-Net on a clinical cohort of T1-weighted (T1w) and T2-weighted (T2w) MRI scans, comparing it with multi-atlas segmentation (MAS) and other DCNNs.

    Main Results:

    • Deep convolutional neural network (DCNN) methods demonstrated superior performance compared to the state-of-the-art multi-atlas segmentation (MAS) approach.
    • The proposed SS-Net achieved the highest median and mean Dice scores among all investigated DCNN baseline methods.
    • SS-Net effectively handled spatial variations and intensity differences in multi-modal MRI scans.

    Conclusions:

    • The Splenomegaly Segmentation Network (SS-Net) offers a robust and accurate solution for automated splenomegaly segmentation in multi-modal MRI.
    • Deep learning, particularly SS-Net, significantly outperforms traditional MAS methods for this task.
    • Accurate spleen segmentation using SS-Net can aid in the non-invasive diagnosis and monitoring of liver and spleen diseases.
