About Dr. Bouchard
Today’s healthcare climate calls for medical technology that provides a safe, inexpensive, patient-specific, and point-of care diagnostic solution. Ultrasound-mediated imaging technologies, such as photoacoustic (PA), contrast-enhanced ultrasound (CEUS), or elasticity imaging, allow clinicians to probe a patient’s specific molecular composition, permit assessment of tissue viscoelasticity, or afford unprecedented contrast for real-time image-guided therapy. Ultrasound-mediated imaging solutions can be provided at a price point, convenience, and operating ease that permits bedside utilization or straightforward intraoperative integration. Consequently, Dr. Bouchard has focused his research program on clinically translatable photoacoustic-ultrasonic (PAUS), CEUS, and acoustic radiation force (ARF)-based elasticity imaging technologies. Specifically, Dr. Bouchard is investigating novel uses of these platforms in the detection, assessment, and treatment-monitoring of cancer and cardiac disease. To this end, Dr. Bouchard has invested considerable effort in development of quantitative imaging approaches for both endogenous (e.g., hemoglobin) and exogenous (e.g., molecularly targeted nanoparticles or phase-changing nanodroplets) in both tissue-mimicking phantom and preclinical (e.g., murine) models.
