Area of Science:

Medical Imaging
Computer-Aided Diagnosis
Renal Anatomy

Background:

Renal cortex segmentation is crucial for diagnosing kidney diseases but remains an under-researched area.
Accurate segmentation of the renal cortex is challenging due to its complex anatomical structure.

Purpose of the Study:

To propose a novel approach for renal cortex segmentation.
To address the renal cortex segmentation problem as a multiple-surfaces extraction task.

Main Methods:

The renal cortex segmentation problem is framed as a multiple-surfaces extraction problem.
An optimal surface search method is employed, incorporating a novel graph construction scheme.
The graph construction models different surface properties and inter-surface relationships.

Main Results:

The proposed method was evaluated on 17 clinical CT datasets.
Achieved a true positive volume fraction (TPVF) of 74.10%.
Demonstrated a low false positive volume fraction (FPVF) of 0.08%.

Conclusions:

The novel approach effectively segments the renal cortex.
The method shows significant promise for clinical applications in kidney imaging analysis.
