Real-time cavitation monitoring during optical coherence tomography guided photo-mediated ultrasound therapy of the retina

Photoacoustic-mediated ultrasound therapy (PUT) is a novel anti-vascular therapeutic modality based on cavitation-induced bioeffects. During PUT, the synergistic combination of laser pulses and ultrasound bursts is used to precisely remove microvessels and stop local blood perfusion. Due to its high precision on microvessel removal, PUT holds great potential in ophthalmology as an alternative treatment modality Continue Reading »

Transforming Vascular Malformation Treatment with Groundbreaking Ultrasound + Laser Technology

Port-wine stains (PWS) are not merely cosmetic concerns but congenital conditions characterized by an abnormal dilation of capillaries, impacting a small fraction of newborns. These marks often grow more pronounced and resistant to treatment as one ages, potentially leading to hypertrophic conditions. Beyond the physical manifestations, PWS significantly affects individuals’ social interactions and psychological well-being Continue Reading »

Photoacoustic mapping of tumor oxygenation predicts radiotherapy efficacy

Advances in radiation therapy have revolutionized the treatment of cancer, but the efficacy of treatment can vary significantly among patients. Recent developments in imaging techniques have enabled clinicians to monitor changes in tumor structure to assess response to radiation therapy.

Tracking radiation treatment in real time promises safer, more effective cancer therapy

The ability to accurately detect where X-rays land and in what dose could reduce the collateral damage from radiation therapy.

Radiation, used to treat half of all cancer patients, can be measured during treatment for the first time with precise 3D imaging developed at the University of Michigan.

By capturing and amplifying tiny sound waves Continue Reading »
