Hollow alginate microfibers (od = 1.3 mm, id = 0.9 mm, th = 400 µm, L = 3.5 cm) comprised of 2% (w/v) medium molecular weight alginate cross-linked with 0.9 M CaCl₂ were fabricated to model outward diffusion capture by 2D fluorescent microscopy. A two-fold comparison of diffusivity determination based on real-time diffusion of Fluorescein isothiocyanate(More)
The effectiveness of localized drug delivery as a treatment for breast cancer requires sufficiently high therapeutic dose, as well as an ability to image the drug for proper spatial targeting. To balance treatment potential and imaging capabilities, we have begun to design a novel drug reservoir using microcapsules that are large in size (> 30 µm) but(More)
INTRODUCTION Ultrasound based strain imaging is becoming popular for breast tumor differentiation on the basis that malignant cancers are stiff [1]. One implementation of this technique is to apply a small free-hand compression to the breast during which ultrasound radio-frequency (RF) data is recorded. RF data is processed to estimate spatial deformation,(More)
