The Bronchial Tree

The Bronchial Tree

The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

The Tree of Life - Bacteria, Archaea, Eukaryotes

The Tree of Life - Bacteria, Archaea, Eukaryotes

The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

Survival Tree

Survival Tree

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Phylogenetic Trees

Phylogenetic Trees

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

Dimensional Analysis

Dimensional Analysis

Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Area of Science:

Thoracic Surgery
Medical Imaging
Biomedical Engineering

Background:

Pulmonary segmentectomy procedures are increasing due to a rise in small lung cancer cases.
Accurate identification of the target bronchus during surgery remains challenging, even with pre-operative 3D computed tomography (CT).

Observation:

A novel approach utilizing a 3D-printed model of the bronchi was investigated for pre-operative planning.
The 3D-printed model, made from a soft, mobilizable material, accurately replicated the actual bronchi.

Findings:

The 3D-printed model proved effective in pre-operatively determining the correct bronchus for transection.
The model's tactile properties allowed for intraoperative simulation, mimicking the actual bronchus during surgery.

Implications:

This 3D modeling technique can significantly improve surgical accuracy and confidence in pulmonary segmentectomy.
Enhanced pre-operative planning through 3D models may lead to better patient outcomes in lung cancer treatment.
