Computed Tomography01:10

Computed Tomography

8.2K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Area Computation by the Alternative Coordinate Method

613
The alternative coordinate method, also known as the Shoelace Formula, is a technique for determining the area of a traverse using Cartesian coordinates. This method relies on the sequential arrangement of x and y coordinates for each point of the shape, ensuring accuracy and ease of application.In this approach, each corner's x and y coordinates are listed as fractions, with the x-coordinate as the numerator and the y-coordinate as the denominator. These coordinates are arranged sequentially...

Design Example: Traverse Angle Computations

335
Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

Positron Emission Tomography01:29

Positron Emission Tomography

7.2K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

The Role of Ion Channels in Neuronal Computation01:19

The Role of Ion Channels in Neuronal Computation

3.8K
A postsynaptic neuron usually receives numerous impulses from several other presynaptic neurons. The axon hillock of the postsynaptic neuron integrates all these signals and determines the likelihood of firing an action potential.
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....

Area of Science:

  • Comparative anatomy
  • Biomedical imaging
  • Zebrafish research

Background:

  • Zebrafish are valuable research models due to their manipulable genomes.
  • Standardized methods are needed for assessing spinal deformities in zebrafish models.
  • Previous studies lacked consistent methodologies for spine evaluation.

Purpose of the Study:

  • To establish a feasible and reproducible micro-CT method for evaluating zebrafish spine structure.
  • To determine normal spinal parameter values in coronal and sagittal planes.
  • To assess the efficacy of micro-CT in measuring spinal angles under induced stress.

Main Methods:

  • Micro-computed tomography (micro-CT) was utilized with 59μm resolution.
  • Two observers analyzed 15 zebrafish (12 adults, 3 juveniles).
  • External stresses were applied to mimic scoliosis in 6 animals.

Main Results:

  • Defined assessment planes for sagittal and coronal spinal parameters.
  • Established mean thoracic kyphosis: 20.5°±5.0° (adults) and 8.7° (juveniles).
  • Micro-CT effectively quantified induced spinal deformities, including Cobb angles.

Conclusions:

  • A standardized micro-CT protocol for zebrafish spine assessment was developed.
  • Normal spinal parameter ranges were identified (thoracic kyphosis <30°, coronal <10°).
  • The method is effective for evaluating induced spinal deformities in zebrafish models.
