Biomedical Imaging

The Biomedical Imaging research groups in the Marquette Medical College of Wisconsin Joint Department of Biomedical Engineering focus on developing new techniques to noninvasively visualize the structure and function of living systems for clinical analysis and medical intervention. Below, learn more about the many BME laboratories contributing to the development of novel imaging technologies and other advancements in this field.


Biomedical Imaging Laboratories


Lens from Ocular Imaging Technology employed by the Advanced Ocular Imaging ProgramAdvanced Ocular Imaging Program

Dr. Joseph Carroll and researchers in the Advanced Ocular Imaging Program (AOIP) use non-invasive imaging techniques—such as optical coherence tomography and adaptive optics scanning light ophthalmoscopy—to examine both the structure and function of the living eye.  The AOIP collaborates with researchers around the world to advance the application of these and other ocular imaging tools to a range of retinal and systemic diseases.

Biophotonics Sensor developed in the Biophotonics LaboratoryBiophotonics Laboratory

The Biophotonics Laboratory develops optical imaging, spectroscopy, and sensing techniques for non- or minimally invasive detection and treatment of cancers and other conditions. Current projects include deep-ultraviolet fluorescence scanning microscopy for intraoperative assessment of breast tumor margins, smartphone microendoscopy for cervical cancer screening, laser ablation of liver tumors with real-time monitoring, optical confirmation and monitoring of endotracheal tube position, and photo-biomodulation or low-level laser therapy.

Isolated rodent lung on ventilation-perfusion machineComputational Lung Physiology Laboratory

The Computational Lung Physiology Laboratory (CLPL) uses Micro-CT technology and nuclear medicine to develop experimental and computational strategies to investigate lung physiology at all levels—from molecular, to cellular, to whole-organ and body.  The goal is to identify mechanisms and processes involved in lung diseases and injuries such as sepsis and acute respiratory distress syndrome (ARDS).  The CLPL then develops treatments for these diseases that target the elucidated mechanisms.
