SLIDE 9: Monitoring Response to Therapy

  • RECIST Criteria -- good start; volumetric would be better.
  • Need Functional Response Indicators - "molecular imaging".
  • Generic, "downstream" indicator vs. specific, targeted probe?

SLIDE 10: Chemotherapy Response by MRI & MRS

  • Images of tumor and MR spectra showing changes in spectral peaks during initial therapy and relapse.
  • There was a partial response to AC, regrowth on taxol; the final pathology was viable IDC and extensive DCIS.
  • Time frame is pre-taxol, days 1, 42, 70, 112 and 178.
  • The patient had taxol before surgery because she had clinically palpable lymph nodes

SLIDE 27: Surgical Robots

This figure illustrates several current or envisaged robotic systems that must work in unusual surgical environments.

  • The PAKY robot currently under development by Drs. Stoianovici, Taylor and Whitcomb, at Johns Hopkins, is to be used for radiologically guided percutaneous needle insertion. This robot has received an IRB approval for renal access procedures. The future plan is to evolve this device into a miniature remote-center-of-motion (RCM) manipulator with high tool tip angular mobility (>90 degrees) and precision (2-25 mm over 10-15 cubic work volumes).
  • The long term goal is to employ the PAKY and mini-RCM devices in hostile environments such as in x-ray and computerized tomography machines.
  • The slide also illustrates MR compatible robot under development and evaluation by Dr. Kikinis. This robotic system will soon be employed at Brigham and Women’s Hospital. The proposed robotic systems will employ non-ferromagnetic materials will work in the open magnet machine. Future MR compatible robot will use the MR tagging and MR coils developed under the previous sub-thrust.
