International Classification:

A61B 812

US Classification:

600462

Abstract:

A transesophageal ultrasound probe allowing for scan-plane rotation comprises an endoscope with a probe head connected to the distal end of the endoscope. A transducer is secured to the probe head. A transfer mechanism is connected to the transducer. A motor at the distal end of the endoscope is connected to the transfer mechanism. Finally, an electrical wire is connected to the motor. The transesophageal ultrasound probe uses a motor in the tip of the transesophageal ultrasound probe for scan-plane rotation.

US Classification:

600462

Abstract:

G. E. DOCKET NUMBER 15-DS-00536A system and method for measuring a position of an imaging element located within a scanhead of an imaging probe, such as transesophageal ultrasound probe, is provided. The imaging probe may be used in a medical imaging system and/or a three-dimensional imaging system. The probe includes an articulating portion having a scanhead. The scanhead includes an imaging element, such as a transducer, and a position sensor positioned within the scanhead. Preferably, the position sensor is connected to the imaging element via an axle. Therefore, the rotation of the position sensor is synchronized to the rotation of the imaging element. The location of the position sensor within the imaging element provides accurate measurement of the position of the imaging element. The position sensor preferably includes a code disk having apertures and a system of light emitters and detectors. As the code disk rotates in synchronization with the imaging element, the pattern of detection of light through the apertures measures the position of the imaging element.

Inventors:

Jonathan E. Snyder - Oklahoma City OK

Assignee:

Corazonix Corporation - Oklahoma City OK

International Classification:

A61B 1000

US Classification:

128660

Abstract:

An omnidirectional ultrasonic probe, having specific application for connection to the distal end of an esophageal catheter, includes a support member upon which are coaxially mounted a transmitter member, a receiver member, and one or more acoustic reflector members. The acoustic reflector member or members reflect transmissions and receptions of ultrasonic signals along substantially parallel paths. The reflector members also provide omnidirectional reflection. Separate transmitter and receiver members are used in the preferred embodiments to facilitate continuous wave operation.

US Classification:

378 44, 378 51, 378 62

Abstract:

An x-ray system with multiple dynamic range selections. The system including an x-ray source and a detector, wherein the detector includes a scintillator and a pixel. The pixel includes a photodiode and first and second capacitors connectable to the photodiode. The pixel is configured to be switched between a first state where only the first capacitor is connected to the photodiode and a second state where both capacitors are connected to the photodiode. The x-ray source directs x-rays to the detector and a region of interest positioned between the source and detector, the scintillator converts the x-rays to light, and the pixel photodiode converts the light to an electrical charge. The charge is stored in the first capacitor when the pixel is in the first state and in the first and second capacitors when the pixel is in the second state.
