  • Publication number: 20250121212
    Abstract: Disclosed is a hydrogel and hydrogel-based foam, which are made of a naturally-derived material, alginate hydrogel in combination with CaCO3, glucono delta-lactone (GDL), and sodium lauryl ether sulfate, as well as methods for making alginate hydrogel and alginate hydrogel foam, which have radiological and mechanical properties equivalent to those of human lung. The material is environment-friendly, and the hydrogel properties can be readily adjusted by changing the alginate concentration, Ca2+ ratio, and solution volume in the container. The hydrogel and hydrogel foam disclosed here have potential to be used for making tissue-equivalent phantoms of various human organs, in particular human lung, for radiotherapy dosimetry, and other applications such as bioimplants, artificial biological tissues, soft robotics, and optics.

  • Patent number: 10290233
    Abstract: A system and method to integrate computational fluid dynamics (CFD) and radiotherapy data for accurate simulation of spatio-temporal flow and deformation in real human lung is presented. The method utilizes a mathematical formulation that fuses the CFD predictions of lung displacement with the corresponding radiotherapy data using the theory of Tikhonov regularization.

  • Publication number: 20070232883
    Abstract: In some embodiments, stress values for a diseased artery are obtained, stress ratios are determined from the obtained stress values, and a flow-structure interaction index is generated based upon the stress ratios as a function of a given plaque characteristic. In further embodiments, a plaque characteristic of a patient is determined, a patient's stress ratio is determined in relation to the flow-structure interaction index and the plaque characteristic, and the patient's stress ratio is compared to a critical stress ratio to determine whether the patient's stress ratio exceeds the critical stress ratio.

  • Publication number: 20070191682
    Abstract: Disclosed are optical probes and methods for use of such probes. In one embodiment, an optical probe includes a housing that is sized and configured to be passed through a lumen having an inner diameter no greater than approximately 2 millimeters, and an internal optical system provided within the housing, the optical system being configured to capture images of a feature of interest associated with the lumen. In another embodiment, an optical probe includes a housing configured for passage through a narrow lumen, and an internal optical system provided within the housing that is configured to capture images of a feature of interest associated with the lumen, the optical system including axicon optics that form a focal line rather than a discrete focal point.
