Project Description

Objective

  • Automatic segmentation of prostate gland on MRI data for preoperative planning and/or guided biopsy.

Approach, Plan

Progress

  • Preliminary results (before project week):

Dice coefficient: median = 0.704

5° percentile = 0.485

95° percentile = 0.850

Average Hausdorff Distance (mm): median = 3.691

5° percentile = 1.790

95° percentile = 7.124

95° percentile Hausdorff Distance (mm): median = 8.903

5° percentile = 4.988

95° percentile = 17.498

Required time:

roughly 10 minutes per case.


  • Added in Plastimatch the registration initialization based on the alignment of center of gravity of contours


  • Currently results (at the end of the project week):

Dice coefficient: median = 0.778

5° percentile = 0.482

95° percentile = 0.854

Average Hausdorff Distance (mm): median = 3.005

5° percentile = 1.632

95° percentile = 6.750

95° percentile Hausdorff Distance (mm): median = 8.133

5° percentile = 4.448

95° percentile = 12.895

Required time:

roughly 2 minutes per case.
