  • Publication number: 20170049591
    Abstract: This disclosure provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device includes a stent having a plurality of longitudinally extending filaments. The stent also has an inner surface and an outer surface and a plurality of tubular members extending along the stent. Each of the plurality of tubular members is coupled with one or more of the plurality of longitudinally extending filaments and each of the plurality of tubular members is configured to accept a radioactive element, a spacer or both.

  • Publication number: 20070173339
    Abstract: A golf putting template for training golfers to more accurately putt a golf ball towards the cup along the preferred line of travel has a base member with an open area at its forward end that extends rearwardly to define a ball placement area and a center position for placement of the golf ball. An aim line extends rearwardly from the center position for aligning the template with a target line marked on the ground. An arc line extends rearwardly from the center position in a substantially elliptical direction to define the travel of the putter head during the back and forward strokes, which is achieved through rotation of the golfer's shoulders. Tracking lines perpendicularly intersect the arc line to guide the putter head face during the putting stroke. A plurality of follow-through lines guide the follow-through swing. Alignment indicia align the golfer's feet and stance relative to the template.

  • Publication number: 20070084474
    Abstract: The present invention discloses a methodology for the characterization and determination of mixed-field dosimetry for 252Cf Applicator Tube (AT)-type medical sources, utilizing ionization chambers, GM counters, and Monte Carlo methods. Unlike the previous methodologies, the present invention discloses a specification of dose to muscle, rather than dose to water, for clinical dosimetry of 252Cf medical sources. A dosimetry protocol, similar to that utilized for ICRU-45, with parameters determined specifically for 252Cf brachytherapy is disclosed. Neutron isodose distributions and data necessary for clinical implementation of 252Cf AT sources are also disclosed herein. Additionally, novel methods for the encapsulation, storage, and delivery/implantation of 252Cf radionuclide sources are disclosed.

  • Publication number: 20050109939
    Abstract: A radiation field detection system, for use with a radiating device, includes a radiation detector configured to receive radiation and to provide radiation strength indicia of amounts of radiation received, a positioning mechanism connected to the radiation detector and configured to physically move the radiation detector, and a processor coupled to the positioning mechanism and coupled to the radiation detector to receive the radiation strength indicia, the processor being configured to: actuate the positioning mechanism to move the radiation detector to desired locations within a radiation field produced by the radiating device; analyze the radiation strength indicia from the radiation detector; correlate positions of the radiation detector with corresponding amounts of received radiation; determine a first location of maximum detected radiation; and determine a first relationship between the first location of maximum detected radiation and a second location of maximum radiation.

  • Publication number: 20050077459
    Abstract: A real, physical radiation phantom for simulating a portion of a human being includes a body portion providing an analytic outer shape of the phantom, the outer shape being similar to a shape of at least a portion of the human being, the body portion having a first physical characteristic of a first value similar to a second value of the first physical characteristic corresponding to human soft tissue, and at least one internal component disposed in the body, the internal component having an analytic shape approximating an internal portion of human anatomy and having a third value of the first physical characteristic different from the first value.
