Improved Image-Guided Laparoscopic Prostatectomy

Abstract

Laparoscopic ultrasound probe has been integrated with the daVinci robotical surgical system. The new integrated system has been tested on tissue mimicking phantoms. Automatic robotic-assisted palpation has been designed, implemented and tested. Two studies have been completed: 1) ex-vivo prostate specimens using standard ultrasound probe as surrogate LAPUS probe and 2) comparative elastography study of LAPUS and TRUS probes on modified prostate elastography phantoms. Results show elastography with LAPUS has the potential to detect prostate cancer through direct interrogation techniques, but there are concerns about probe manipulation due to its size. Advanced 2D and 3D elastography algorithms improve robustness, ability to overcome decorrelated areas. They have been tested and validated on tissue mimicking phantoms, prostate ex-vivo specimens and in-vivo porcine ablated tissue. A robust iterative motion compensation algorithm for strain induced thermal imaging has been developed and it is described. The algorithm was validated on ex-vivo ablated tissue phantoms.
