Photoacoustic Imaging in Detecting Ovarian or Fallopian Tube Cancer

PRIMARY OBJECTIVES: I. To assess the performance of photoacoustic imaging (PAI) in detection of ovarian cancer in a clinical setting and to help improve the design of the next generation hand held PAI probe. SECONDARY OBJECTIVES: I. To evaluate vasculature and oxygen saturation in lesions based on PAI-measurements. OUTLINE: Patients undergo PAI over 15-30 minutes prior to the ovarian excision.
