  • Patent number: 10925579
    Abstract: Described herein are systems and methods for tracking a target tissue during therapy delivery. A system for identifying an anatomical structure and tracking the motion of the anatomical structure using imaging before and during delivery of a therapy to a patient includes an imaging module and a therapy module. In some cases, the imaging module is configured to identify a region of the anatomical structure in an image, and the therapy module is configured to deliver the therapy to a target tissue. A method for imaging during delivery of a therapy includes acquiring an image, identifying a region of an anatomical structure, tracking the region of the anatomical structure, integrating the tracking, generating a unique template library, determining if a pre-existing template matches the results or if the results should be updated as a new template, and delivering the therapy to the target tissue.

  • Patent number: 10394974
    Abstract: A profile of porosities and permeabilities calculated from several sample volumes in a system can speed up computational fluid dynamics (CFDs). Heterogeneous fluid flow paths can be calculation intense, limiting the accuracy of fluid-path models. Further, allowing a user to define a number of sample volumes in a model system allows pre-calculation of porosities and permeabilities for use in Navier-Stokes formulas for modeling fluid flow and gives the user control over calculation time and accuracy. This is helpful, for example, in modeling endovascular interventions where fluid dynamics are determinative in the efficacy or method of treatment for various vascular disorders, such as aneurysms, and heart disease. This is also beneficial in other healthcare contexts, like blood filters, embolic gels, endografts, web devices, and atrial appendage occluders, among others.

    Abstract: A method is provided for preparing an area of the ground surface to be milled by a milling machine. Prior to performing any milling operation on the area of the ground surface, a survey vehicle separate from the milling machine is used to traverse the area. The survey vehicle detects the presence of buried obstacles with a sensor and generates a sensor output signal indicative of the presence of the buried obstacle. The sensor output signal is received in a controller which generates a sprayer actuation signal and responds to the sensor output signal. A marking sprayer is actuated in response to the sprayer actuation signal and sprays the ground surface above the obstacle with a visible marking emitted from the sprayer. Subsequently, a milling machine separate from the survey vehicle may be utilized to mill the ground surface and by observation of the visible markings the operator may avoid impacting the milling drum with the buried obstacles.

  • Patent number: 9867272
    Abstract: A system that generates short charged particle packets or pulses (e.g., electron packets) without requiring a fast-switching-laser source is described. This system may include a charged particle source that produces a stream of continuous charged particles to propagate along a charged particle path. The system also includes a charged particle deflector positioned in the charged particle path to deflect the stream of continuous charged particles to a set of directions different from the charged particle path. The system additionally includes a series of beam blockers located downstream from the charged particle deflector and spaced from one another in a linear configuration as a beam-blocker grating. This beam-blocker grating can interact with the deflected stream of charged particles and divide the stream of the charged particles into a set of short particle packets. In one embodiment, the charged particles are electrons. The beam blockers can be conductors.

  • Patent number: 9671525
    Abstract: Continuous capillary pressure (Pc) curves of subsurface rock formations adjacent wells are determined based on translation relaxation time (T2) data from nuclear magnetic resonance (NMR) and from wireline well logs, such as resistivity logs, to obtain water saturation (Sw) of the rock in the formations. The T2 data and the hydrocarbon density, water density, free water level, and paleo-water level of the formation are processed to obtain parameters of Thomeer hyperbolas that closely conform to water saturation values obtained from the other well logs. The Thomeer hyperbolas so determined are converted to capillary pressure curves.
