摘要:
A multi-functional endoscopic system, for use in electrosurgical applications, that includes an imaging endoscope that may be used in combination with various electrosurgical devices, all of which are sufficiently inexpensive to manufacture, such that the endoscope and electrosurgical devices are considered single use, disposable items. The multi-functional endoscopic system of the present invention is suitable for use with a variety of common electrosurgical devices that require electrical/electronic support in order to function. The electrical/electronic support for these electrosurgical devices (e.g., an electrosurgical generator and associated controls) is integrated with the operator console of the imaging endoscope of the multi-functional endoscopic system of the present invention, rather than provided as a separate device. In another embodiment of the invention, an imaging endoscope is provided that integrates or combines the functions of both an imaging endoscope and an electrosurgical device, which can be controlled by a single handheld controller.

A fluid delivery system for use with an endoscope. Certain embodiments of the invention include a single, large fluid source and pump installed upon an operator console, in combination with a small fluid reservoir and pump installed within a proximal connector of the imaging endoscope, multiple fluid sources that feed a common fluid channel that are pressurized by a common pump, multiple fluid sources that feed dedicated fluid channels that are pressurized by dedicated pumps, and a small fluid reservoir and pump installed within a handheld manual controller of the imaging endoscope. The fluid delivery endoscopic systems of the present invention provide the user with the flexibility of changing fluids either in advance of a procedure or on-the-fly as needed, instead of relying on fixed fluid sources only.
摘要:
One or more techniques and/or systems described herein provide for examining an object (e.g., a tumor in a patient) and subsequently treating the object. The examination and treatment generally occur very close to one another in time, with the patient remaining on a support article (e.g., on a bed or in a chair) during both the examination and the treatment. In this way, a position of the tumor and/or orientation of the tumor relative to the patient is substantially fixed during both the examination and the treatment. In one embodiment, a support article is configured to rotate during the examination and/or treatment. In this way, the object can be examined (e.g., and volumetric data related to the object can be acquired) and/or treated without moving portions of the imaging and/or treatment apparatus, for example.

A hybrid MRI-particle-based therapy system can include as components both a particle radiation therapy system configured to apply a charged particle beam to a region of application in a predetermined direction and also a MRI system including a magnetic field generator for generating a magnetic field in an imaging volume which includes the region of application at the same time that the charged particle beam is applied. The MRI system can be configured with two torroidal magnets or a magnet having apertures to provide access to the region of application for the charged particle beam, and to provide a homogeneous magnetic field in the region of application of the charged particle beam. The particle beam can be positioned to pass through a relatively low-strength portion of the main magnetic B0 field of the MRI system. Related methods of image-guided therapy are also provided by embodiments of the present disclosure.

Disclosed is an apparatus for the generation of large currents of negative ions for use in tandem accelerators, suitable for employment in ion implantation on an industrial production scale. The apparatus includes a high current positive ion source which is coupled to a charge exchange canal where a fraction of the positive ions are transformed into negative ions.
摘要:
A method and mechanism for cooling a display device, having an extremely bright light focused on its surface and is mounted inside a closed chassis, by conducting heat from the device directly to the chassis walls, where the heat is then transferred to the lower temperature air of the ambient surroundings. The mechanism uses an adjustable mechanical linkage to close the gap and make a good thermal contact between the projection device package or heat sink stud and the chassis wall. This approach reduces the requirements for large heat sinks and noisy cooling fans found in many conventional projection systems.
摘要:
As geometries of semiconductor devices shrink in size and the number of circuits per unit area increase, a number of the ion implants required to fabricate these devices will use very low energies (as low as 2 keV). In the present invention, a technique is utilized that generates substantial beam currents at low energies utilizing ion sources that are standard in the industry. Molecular ions are extracted from the plasma of the ion source at voltages numerically higher than the desired electron voltage at which the desired atomic ions are to strike the target, and are then dissociated into components which include the desired atomic ions moving with an energy which is a fraction of that at which the molecular ions were extracted.
摘要:
One or more techniques and/or systems are described herein for cleaning a portion of a radiographic examination apparatus whereon debris may accumulate. Typically, the portion being cleaned is within a scanning field of the radiographic examination device (e.g., within a portion of the radiographic examination device through which radiation traverses). Activation of a cleaning mechanism, or a portion thereof, may be timed to miss radiation emitted during a scan, and thus not interfere with a scan. Also, the cleaning mechanism, or a portion thereof, may be located so as to not attenuate radiation. If radiation is attenuated by the cleaning mechanism corrective techniques can be implemented to account for such attenuation.
摘要:
A package that resists creation of particles in a package cavity. A package according to one embodiment of the present invention contains a mechanical device attached to the floor of the package substrate. Epoxy typically is used to attach the device. Electrical connections are provided by bond wires connecting bond pads on the substrate with bond pads on the device. A window is attached to the substrate to form a cavity around the device. A thin masking layer on portions of the package cavity surface prevents the surface from generating particles. The thin masking layer may be any material that resists particle generation. The masking layer on the cavity walls optionally extends out of the cavity and onto the upper surface of the package.
