Fast fully automatic heart fat segmentation in computed tomography datasets

Area of Science:

• Medical Imaging
• Cardiology
• Artificial Intelligence in Medicine

Background:

• Heart diseases are a major global health concern, often linked to cardiac fat accumulation.
• Accurate segmentation of cardiac fat from medical images is crucial for diagnosis and treatment planning.
• Existing segmentation methods can be time-consuming, limiting their clinical utility.

Purpose of the Study:

• To develop a novel, efficient, and automated approach for segmenting cardiac fat from Computed Tomography (CT) images.
• To significantly reduce the time required for cardiac fat segmentation compared to existing methods.
• To evaluate the accuracy and efficiency of the proposed segmentation technique as a potential medical diagnostic aid.

Main Methods:
