Appl. No.:

5/422584

James G. Dempsey - Woodside CA

Assignee:

Langley Hill Quarry - Woodside CA

International Classification:

C02C 100

US Classification:

210532S

Abstract:

A sewage septic tank is described having a diversion system for diverting effluent from the tank from one drain field to another. A "Y" is provided on the outlet pipe of the tank to enable the effluent from such tank to be directed to either one of two drain fields. A gate valve is provided at the end of each arm of the Y to allow flow within the drain field associated therewith to be controlled. Thus, the effluent from the septic tank can be periodically diverted from one drain field to another so that such fields are allowed to alternately dry out. The position of the actuator for each of the valves provides a simple visual indication of the state of the valve at any given time.

International Classification:

A61N 5/10
A61B 5/055
A61B 5/00
G01R 33/50

Abstract:

Edema in tissue of a patient undergoing a course of radiation therapy or treatment can be estimated based on one or more MRI measurements used to measure changes in fluid content of various tissues. A correlation between observed changes in edema and one or more delivered fractions of radiation can be used to drive one or more clinical actions. Methods, systems, articles of manufacture, and the like are described.

International Classification:

Abstract:

A radiofrequency receive coil assembly can include a first conductive loop and a second conductive loop electrically connected at a node. The first and second conductive loops can extend into a treatment beam region of the radio frequency receive coil assembly through which one or more beams of ionizing radiation pass. The first conductive loop and the second conductive loop can overlap each other to provide electromagnetic isolation and/or can use a common conductor combined with a shared capacitor to provide electromagnetic isolation, with the shared capacitor or other electrical components, as well as any conductive loop overlaps, being positioned outside of the treatment beam region. These features can, among other possible advantages, minimize and homogenize attenuation of the beams of ionizing radiation by the radiofrequency receive coil assembly.

Abstract:

A device and a process for performing high temporal- and spatial- resolution MR imaging of the anatomy of a patient during intensity modulated radiation therapy (IMRT) to directly measure and control the highly conformal ionizing radiation dose delivered to the patient for the treatment of diseases caused by proliferative tissue disorders. This invention combines the technologies of open MRI, multileaf-collimator or compensating filter-based IMRT delivery, and cobalt teletherapy into a single co-registered and gantry mounted system.

A61N 5/10

Abstract:

A surgical guidance system is disclosed that allows for real-time imaging and patient monitoring during a surgical procedure. The system can include an MRI system for generating real-time images of the patient while surgery is being performed. Prior to surgery, a surgical plan can be created using a planning interface. A control unit receives the real-time image data and the surgical plan, and monitors the image data based on parameters included in the surgical plan. The control-unit monitoring occurs in real-time while the surgical procedure is being performed. The control unit can detect deviations from the surgical plan and/or high-risk patient conditions and instruct an alert unit to issue an alert based on the detected conditions.
