Low-intensity focused ultrasound targeted microbubble destruction reduces tumor blood supply and sensitizes anti-PD-L1 immunotherapy

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Immune checkpoint blockade (ICB) typified by anti-PD-1/PD-L1 antibodies as a revolutionary treatment for solid malignancies has been limited to a subset of patients due to poor immunogenicity and inadequate T cell infiltration.

Ultrasound of the prostate [PDF]

open access: yesCancer Imaging, 2010
Ultrasound is a widely used imaging modality for evaluation of the prostate. The main topic of diagnostic imaging is an improvement of prostate cancer diagnosis. The current available systematic prostate biopsy is performed only under ultrasound guidance, but new imaging techniques allow prostate cancer visualization and therefore improved detection ...

Endobronchial ultrasound [PDF]

open access: yesRespiratory Medicine, 2009
The efficacy and technical aspects of endobronchial ultrasound (EBUS) are reviewed because this technology promises to revolutionise bronchoscopy. EBUS extends the endoscopist's view beyond the mucosal surface of the large airways to peri-bronchial structures and peripheral lung lesions.

Investigating ultrasound–light interaction in scattering media [PDF]

open access: yes, 2020
Significance: Ultrasound-assisted optical imaging techniques, such as ultrasound-modulated optical tomography, allow for imaging deep inside scattering media. In these modalities, a fraction of the photons passing through the ultrasound beam is modulated.
