Imaging Studies III: Computed Tomography

375
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...

Lung Capacity01:47

Lung Capacity

56.3K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Inhaled Medications01:23

Inhaled Medications

803
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Uncertainty in Measurement: Accuracy and Precision

101.8K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Mixing Concrete01:30

Mixing Concrete

390
Concrete mixing ensures a homogenous blend where aggregates are well-coated with cement paste. Concrete mixing is typically done using two main types of mixers: batch and continuous. Batch mixers handle one batch at a time, thoroughly combining materials before discharging and receiving the next batch. In contrast, continuous mixers receive a steady flow of ingredients, mixing them consistently and discharging without interruption. Within batch mixers, tilting drum mixers mix with internal...

Mixing Time01:19

Mixing Time

481
The concept of mixing time is significant in producing a uniform concrete mix with the required strength. The mixing period starts once all components are in the mixer. Initially, the mixer is charged with 10% of the water, followed by the consistent addition of solids and then 80% of the water. The remaining water is added later, within the first quarter of the mixing period. The minimum mixing time varies according to the mixer's capacity; for example, mixers with up to 1 cubic yard...

Area of Science:

  • Medical Imaging
  • Surgical Technology
  • Virtual Reality

Background:

  • Traditional computer-assisted surgery systems display 2D CT images, limiting the surgeon's 3D visualization of pulmonary vasculature and trachea.
  • Accurate visualization of complex 3D anatomical structures is crucial for minimally invasive lung cancer surgery.

Purpose of the Study:

  • To develop and implement a computer-assisted system for precise lung surgery using medical imaging and virtual reality (VR).
  • To improve the visualization of 3D pulmonary vessels and trachea for surgeons.

Main Methods:

  • Utilized regional growth and a filling algorithm for segmenting lung trachea and vessels.
  • Employed a reference edge grid algorithm to construct 3D models of segmented structures.
  • Saved anatomical models in STL file format for use in a mixed reality (MR) device.

Main Results:

  • Successfully developed a computer-assisted system integrating medical imaging and VR for precise lung surgery.
  • The system displays accurate 3D models of pulmonary vessels and trachea on a mixed reality device.
  • Surgeons can precisely observe and interact with the patient's 3D lung structures.

Conclusions:

  • The developed VR-based system enhances surgical precision in lung cancer operations.
  • Improved 3D visualization of pulmonary anatomy aids surgeons in performing accurate and minimally invasive procedures.
