Prostate cancer is commonest cancer in men.  Surgical approach (Radical Prostatectomy) remains mainstay of treatment for localized disease.  Achieving negative surgical margins and preservation of nerves for maintenance of potency are major challenges.  The purpose of this study was to develop an image fusion system for guiding surgeons to optimize outcome of surgery.


DICOM images of prostate are obtained through MR or PET scans. Area of prostate cancer on MRI was delineated by expert radiologists and depending on size of the lesions a number of images were recorded.  These images were then fused with videos of surgical procedure. Various algorithms and software’s like Windows movie maker, Filmora (wondershare), Movavi, AVS, Sony Vegas, Virtual dub, Bynder etc.


We achieved a successful image fusion method through integration of DICOM images into videos of laparoscopic radical prostatectomy (Figure a).  Surgeon could easily identify the abnormal areas in prostate and modify his/her dissection respecting oncological principles of surgery. We are in a process of testing and re-testing these algorithms and test this in real life scenarios following further regulatory approval. On the video below there are different images.


Based on simple software method, we have achieved a successful image fusion method between videos and DICOM image which can further be used by surgeons as a guide to accomplish procedure.
