Virtual reality for 3D histology: multi-scale visualization of organs with interactive feature exploration

Area of Science:

• Biomedical Engineering
• Digital Pathology
• Computational Biology

Background:

• Virtual reality (VR) provides immersive and engaging data visualization.
• VR facilitates novel methods for exploring scientific data.
• This study utilizes VR for visualizing 3D histology data, introducing a new digital pathology interface for cancer research.

Purpose of the Study:

• To develop a novel virtual reality interface for the visualization of 3D histology data.
• To enhance digital pathology workflows for cancer research.
• To create an interactive platform for exploring complex biological datasets.

Main Methods:

• 3D modeling of whole organs and embedded objects of interest.
• Integration of quantitative features and high-resolution histology image patches.
• Implementation of a multi-scale VR application with organ and sub-organ levels.
• Inclusion of data layers for histology images and quantitative features.

Main Results:

• An interactive VR application allowing users to customize visualization properties and interact with various data objects.
• Demonstration using whole mouse prostates with prostate cancer tumors as case studies.
• Incorporation of quantitative histological features relevant to tumor biology within the VR model.
• Enabled exploration beyond the limitations of traditional 2D digital pathology views.

Conclusions:

• The VR application offers a new method for exploring high-resolution, multidimensional biomedical data.
• The platform is suitable for teaching and researcher training in biomedical fields.
• Automated data processing allows for easy adaptation to visualize other organs and pathologies.
