Patent number: 6725075Abstract: A pulse oximeter sensor has both a reusable and a disposable portion. The reusable portion of the sensor preserves the relatively long-lived and costly emitter, detector and connector components. The disposable portion of the sensor is the relatively inexpensive adhesive tape component that is used to secure the sensor to a measurement site, typically a patient's finger or toe. The disposable portion of the sensor is removably attached to the reusable portion in a manner that allows the disposable portion to be readily replaced when the adhesive is expended or the tape becomes soiled or excessively worn. The disposable portion may also contain an information element useful for sensor identification or for security purposes to insure patient safety. A conductive element that allows a pulse oximeter monitor to read the information element is located on the disposable portion in such a way that continuity is broken when the adhesive tape become torn, such as upon removal from the measurement site.Type: GrantFiled: April 23, 2002Date of Patent: April 20, 2004Assignee: Masimo CorporationInventor: Ammar Al-Ali

Patent number: 6725076Abstract: The two-dimensional velocity vector using a pulsed ultrasound field can be determined with the invention. The method uses a focused ultrasound field along the velocity direction for probing the moving medium under investigation. Several pulses are emitted and the focused received fields along the velocity direction are cross-correlated. The time shift between received signals is found from the peak in the cross-correlation function and the velocity is thereby determined.Type: GrantFiled: January 25, 2002Date of Patent: April 20, 2004Assignee: B-K Medical A/SInventor: Jørgen Arendt Jensen

Patent number: 6725078Abstract: A system which coordinates proton beam irradiation with an open magnetic resonance imaging (MRI) unit to achieve near-simultaneous, noninvasive localization and radiotherapy of various cell lines in various anatomic locations. A reference image of the target aids in determining a treatment plan and repositioning the patient within the MRI unit for later treatments. The patient is located within the MRI unit so that the target and the proton beam are coincident. MRI monitors the location of the target. Target irradiation occurs when the target and the proton beam are coincident as indicated by the MRI monitoring. The patient rotates relative to the radiation source. The target again undergoes monitoring and selective irradiation. The rotation and selective irradiation during MRI monitoring repeats according to the treatment plan.Type: GrantFiled: January 4, 2001Date of Patent: April 20, 2004Assignee: St. Louis UniversityInventors: Richard D.

Patent number: 6725079Abstract: A dual pointing device to be used in cooperation with an imaging apparatus, a tracking system, and an object to be imaged. The dual pointing device provides a means for tracking a point on in image in both the image's frame of reference and Euclidean absolute coordinates. This is accomplished by having two tracking systems follow the dual pointing device. Since the two tracking systems follow the same physical device, and since one tracking system operates in the image coordinates while the other tracking system operates in the absolute coordinates, the device makes it possible to effect automatic transformations between the two systems. More specifically, in the preferred embodiment of the dual pointing device, which is intended for use with a magnetic resonance imager, the absolute tracking system is based on infra-red reflectors on the device that are tracked by an infrared transponder.Type: GrantFiled: June 20, 2001Date of Patent: April 20, 2004Assignee: Odin Medical Technologies, Ltd.Inventors: Yuval Zuk, Ehud Katznelson
