  • Patent number: 11170973
    Abstract: An ion source with a target holder for holding a solid dopant material is disclosed. The ion source comprises a thermocouple disposed proximate the target holder to monitor the temperature of the solid dopant material. In certain embodiments, a controller uses this temperature information to vary one or more parameters of the ion source, such as arc voltage, cathode bias voltage, extracted beam current, or the position of the target holder within the arc chamber. Various embodiments showing the connections between the controller and the thermocouple are shown. Further, embodiments showing various placement of the thermocouple on the target holder are also presented.

  • Patent number: 11160454
    Abstract: Described here are systems and methods for visualizing thermal ablation lesions by imaging specific chemical compounds that are created during thermal ablation procedures, such as cardiac ablation procedures. When a cardiac ablation procedure is performed, a central area of coagulative necrosis is created at the treatment site. This necrotic region is surrounded by layers of tissues with ultra-structural and electrophysiological changes. Two particular changes include the denaturation of proteins and the formation of ferric iron containing chemical compounds, such as methemoglobin and metmyoglobin. The formation of and distribution of such chemical compounds can be imaged with the appropriate systems and methods. Accordingly, these chemical compounds can be utilized as biomarkers that indicate the presence and physical characteristics of thermal ablation lesions. Imaging can be performed using magnetic resonance imaging, optical imaging, or photoacoustic imaging, as examples.

  • Publication number: 20210238732
    Abstract: An advanced sputter target is disclosed. The advanced sputter target comprises two components, a porous carrier, and a metal material disposed within that porous carrier. The porous carrier is designed to be a high porosity, open cell structure such that molten material may flow through the carrier. The porous carrier also provides structural support for the metal material. The cell sizes of the porous carrier are dimensioned such that the capillary action and surface tension prohibits the metal material from spilling, dripping, or otherwise exiting the porous carrier. In some embodiments, the porous carrier is an open cell foam, a weave of strands or stacked meshes.

  • Patent number: 10957509
    Abstract: An ion source with an insertable target holder for holding a solid dopant material is disclosed. The insertable target holder includes a hollow interior into which the solid dopant material is disposed. The target holder has a porous surface at a first end, through which vapors from the solid dopant material may enter the arc chamber. The porous surface inhibits the passage of liquid or molten dopant material into the arc chamber. The target holder is also constructed such that it may be refilled with dopant material when the dopant material within the hollow interior has been consumed. The porous surface may be a portion of a perforated crucible, a portion of a perforated retention cap, or a porous insert.

  • Publication number: 20210052854
    Abstract: A steering device and navigation system for interventional procedures. Included are devices, systems, and methods that incorporate a steering device which consists of an expandable structure that can be controlled to spread out within the vessel lumen, or cardiac chamber, and may apply circumferential force to the tissue. This structure, once spread out, can anchor relative to the anatomy and provides support for an internal catheter through a set of strings connected to the internal catheter. The internal catheter is configured to allow an interventional device, such as a guidewire or catheter, to pass through it. Using the strings that are connected to actuation mechanisms within the device's handle, the internal catheter can be manipulated to allow controlling the position of a device that runs within it or is connected to it and can be used for the purpose of navigation of devices and obtaining measurements from known positions.

  • Patent number: 10818469
    Abstract: An indirectly heated cathode ion source having a cylindrical housing with two open ends is disclosed. The cathode and repeller are sized to fit within the two open ends. These components may be inserted into the open ends, creating a small radial spacing that provides electrical isolation between the cylindrical housing and the cathode and repeller. In another embodiment, the repeller may be disposed from the end of the cylindrical housing creating a small axial spacing. In another embodiment, insulators are used to hold the cathode and repeller in place. This design results in a reduced distance between the cathode column and the extraction aperture, which may be beneficial to the generation of ion beams of certain species.

  • Patent number: 10600611
    Abstract: An ion source with a crucible is disclosed. In some embodiments, the crucible is disposed in one of the ends of the ions source, opposite the cathode. In other embodiments, the crucible is disposed in one of the side walls. A feed material, which may be in solid form is disposed in the crucible. In certain embodiments, the feed material is sputtered by ions and electrons in the plasma. In other embodiments, the feed material is heated so that it vaporizes. The ion source may be oriented so that the crucible is disposed in the lowest wall so that gravity retains the feed material in the crucible.

  • Publication number: 20200090916
    Abstract: An ion source with an insertable target holder for holding a solid dopant material is disclosed. The insertable target holder includes a pocket or cavity into which the solid dopant material is disposed. When the solid dopant material melts, it remains contained within the pocket, thus not damaging or degrading the arc chamber. Additionally, the target holder can be moved from one or more positions where the pocket is at least partially in the arc chamber to one or more positions where the pocket is entirely outside the arc chamber. In certain embodiments, a sleeve may be used to cover at least a portion of the open top of the pocket.

  • Patent number: 10460423
    Abstract: Methods for representing multiple scales in an image using a variational algorithm are provided. An iterative decomposition of an image into a total variation (“TV”) part, which may be a weighted TV (“TV?”) part, and a residual part motivates the design and use of a partial differential equation that may be referred to as a multiscale total variation flow, or multiscale weighted total variation flow. This produces a multiscale representation of the image. The speed of this decomposition can be controlled with a user-defined function, and is fast enough to allow for real-time applications of denoising and image registration.

  • Publication number: 20190274569
    Abstract: A new MRI imaging sequence, the Septal Scout, has been presented. This new technique can accurately determine the timing of diastasis windows for the purpose of cardiac gating in applications such as high-resolution coronary MRA. The Septal Scout acquires 1D MR images along the long-axis of the basal ventricular septum either through projection imaging or 2D excitations. Each acquisition produces a line of data along the ventricular septum. The acquisition is repeated over time to generate a time-map of Septal Scouts. The data from the Septal Scout time-map is processed to generate a velocity graph of an ROI near the basal septum. From this graph, the beginning and end of diastasis is determined. This timing information is available for use to facilitate cardiac gating in subsequent high-resolution MR angiography.
