A plasma torch employs a dielectric resonator excited at separate locations with phase shifted signals to provide more uniform current flow through the resonator. High-power operation is possible while protecting the dielectric by using a combination segregated spiral flow and linear flow cooling air at different rates. Microwave leakage from the plasma resonant chamber is contained by conductive metal chokes.

A portable, modular plasma source allows the production of an emission spectrometer by combination with a common portable fiber optic spectrograph by channeling emitted light through a fiber optic coupling communicating light from the plasma source to the portable fiber optic spectrograph.

Portable plasma source for optical spectroscopy

A dielectric resonator is excited at its natural resonant frequency to produce a highly uniform electric field for the generation of plasma. The plasma may be used as a desolvator, atomizer excitation source and ionization source in an optical spectrometer or a mass spectrometer.

Microwave plasma spectrometer using dielectric resonator

A plasma unit for a mass spectroscopy machine generates plasma using a microwave coupled dielectric ring held within a microwave cavity employing part of the mass spectrometer structure to define the microwave cavity, thereby permitting improved proximity of the plasma and plasma ionized sample material to the mass spectrometer aperture.

MR imaging and intervention functions are localized within a single device. At least one integrated coil device which has at least one RF coil, a housing which encases the RF coil and provides an anatomically conformal surface, and a plurality of apertures. The integrated coil device slides along a guide rail system to adjust the size of a patient anatomical imaging region. The apertures in the integrated coil device are available to secure tool holder grid plate inserts or other interventional device guides. The inserts assist in holding the soft tissue for diagnostic imaging and provide support for biopsy/interventional instrument guides. The integrated MR imaging and interventional coil device works in combination with a prone patient support structure, an adaptive torso sling, and also features an open architecture design for improved patient access. The device also works for supine or side imaging procedures.

A compact and versatile power meter is created through the use of a discrete component network providing for phased splitting and combining of signals obtained at taps along a transmission conduit having a predefined phase separation. The use of the discrete component network eliminates the need for bulky waveguides or microstrip antenna designs, the latter providing phase shift through their physical dimensions.

Two halves of a separable wrist coil provide a coil volume closely conforming to a patient's hand yet separable for insertion and removal of the hand. The halves are hinged allowing easy one-handed operation of the coil in which an operator may stabilize the patient's hand within a propositioned coil with one hand while closing the coil and locking it in position with the other. Detents and a manual lock assist in this process.

Wrist coil for magnetic resonance imaging

The vest provides a simple and intuitive coil support assuring proper alignment of the coils with the patient and providing support for coil elements encircling the opposed arms. A coil for receiving and/or transmitting radio-frequency signals for magnetic resonance imaging of the chest, and particularly for ventilation studies of the lungs, is supported in a flexible vest having arm holes locating the coil elements about the patient.

A modular lower coil provides for a head, a vascular and, a thoracic/lumbar element that may interfit or be separated to provide individual imaging of these areas or a combined imaging region stretching from the head to the lower spine. A switch box allows individual ones of these elements to be connected to the MRI machine if necessary because of a limitation of inputs to the machine and provides for decoupling currents to minimize interference between the coil elements when one element is being used.

Modular local coil set for magnetic resonance imaging

A cable routing system for an MRI coil having multiple loops and multiple signal cables provides a non-resonant conductive ring surrounding the loops and grounded to define a low electrical field region along which the signal cables may be routed for reduced interference.

A head coil for magnetic resonance imaging may be shortened longitudinally to provide for better access by a patient. Extension of the coil may be performed after the positioning of the patient's head significantly simplifying patient positioning with respect to the coil. A portion of a conductor support sliding over the patient's head removable to allow endotracheal tubes or the like to remain undisturbed.
