ProstAtlas: a digital morphologic atlas of the prostate.

Area of Science:

• Medical imaging
• Biomedical engineering
• Urologic oncology

Background:

• Prostate cancer treatment increasingly utilizes computer-aided interventions and robotics.
• Clinical deployment requires rigorous in vivo and in silico validation.
• Developing accurate anatomical models is crucial for these validation processes.

Purpose of the Study:

• To develop a digital morphologic atlas of the prostate gland, including the peripheral zone and central gland.
• To provide a validated tool for the assessment of computer-aided medical interventions and robotic surgery for prostate cancer.

Main Methods:

• Utilized an image database from 30 selected prostate cancer patients.
• Applied principal component analysis (PCA) to derive mean shapes and key deformations.
• Constructed a digital atlas representing the gland, peripheral zone, and central gland.

Main Results:

• A comprehensive digital morphologic atlas of the prostate was successfully developed.
• The atlas captures the mean shape and significant anatomical variations.
• Demonstrated the atlas's utility in image simulation and physical phantom design.

Conclusions:

• The developed digital prostate atlas serves as a valuable tool for in silico and in vivo validation.
• This atlas can enhance the development and testing of advanced prostate cancer interventions.
• Facilitates the routine clinical deployment of computer-aided medical and robotic procedures for prostate cancer.
