Filed:

Nov 8, 2002

Appl. No.:

10/291034

Inventors:

James Jago - Seattle WA
David Rust - Seattle WA

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

A61B 800

US Classification:

600447, 600443, 73625

Abstract:

A process for setting a focus in a ultrasonic imaging system includes receiving a point of interest and range of interest by a user input. A system controller of the system sets a focus zone on the point of interest and adjusts the aperture and apodization for the range of interest. If the range of interest can not be covered by one focal zone, further focal zones are added.

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

A61B 800

US Classification:

600443

Abstract:

An ultrasonic diagnostic imaging system processes echo information signals by means of detecting, for different regions of the patients anatomy, the actual noise present for that particular examination, under existing environmental conditions, and in imaging system itself. The noise detected is used to create an actual noise signature for the actual noise present in that particular examination under existing environmental conditions and in the imaging system itself, and the noise signature is used to maximize available dynamic range to create the highest resolution scan images possible while rejecting noise. In a preferred embodiment the dynamic range and noise rejection level are varied for different regions of a patients anatomy as a function of all scanning coordinates being used, including varying depths, steering angles, and linear positions for both sector-type and linear-type scans.

International Classification:

G08B 1/08

US Classification:

3405391, 34053921, 3405681

Abstract:

A wireless ultrasound probe has a probe case enclosing a transducer array, an acquisition circuit, a transceiver and a battery. The probe also includes a loudspeaker which produces audible sounds as a function of the range between the wireless probe and a host system. When the probe is within a near field range of the host system, the loudspeaker is silent. But if the probe is moved to an intermediate or a far field range from the host system, the loudspeaker sounds an alert. This audible alert can be used to locate the probe by transmitting a paging signal which, upon reception by the probe, causes the probe to sound its alert. If the probe is moved to an unauthorized location where it is within range of a transmitter or receiver, the reception of a signal by the probe, the transmitter, or receiver will sound an alert signaling the unauthorized presence of the wireless probe.

International Classification:

G06F 3/033

US Classification:

345158, 345 63, 345 72, 600453, 600459

Abstract:

An ultrasound imaging system includes an ultrasound probe receiving echo signals from a subject, and a processor converting echo signals received from the probe to echo data corresponding to an ultrasound image. The system also includes a grayscale mapper transforming the echo data received from the processor to a corresponding value of perception data. The grayscale mapper makes this transformation using a DICOM compliant GSDF calibration curve. The perception data is passed to a transform processor, which also receives an ambient light signal from an ambient light sensor. The transform processor converts the perception values to respective digital driving levels based on the ambient light signal and display characteristics of a display device to which the digital driving levels are applied to maintain optimal image display under varying ambient light conditions.

Assignee:

KONINKLIJKE PHILIPS ELECTRONICS N.V. - EINDHOVEN

International Classification:

A61B 8/00

US Classification:

600437

Abstract:

An ultrasonic diagnostic imaging system is described which produces images in accordance with a display standard such as the DICOM standard. The DICOM standard images may be exported and reproduced on other display devices such as workstations and film or image printers. The standardized images produced by the system are transformed into unique driving levels which are characteristic of the system display device for viewing. The transform is user controllable for viewing standardized images under differing ambient light conditions.

International Classification:

A61B 8/14
A61B 8/00

US Classification:

600453, 600459

Abstract:

A wireless ultrasound probe has a probe case enclosing a transducer array, an acquisition circuit, a transceiver and a battery. The probe also includes a loudspeaker which produces audible sounds during use of the probe. The loudspeaker, which may be a piezoelectric loudspeaker, issues an alert when battery power is low or signal strength of the wireless transmission is poor or nonexistent. The loudspeaker can provide user feedback to the actuation of a button or control on the probe. The loudspeaker can provide haptic feedback during use of the probe, and can be used to produce audio Doppler tones or heart sounds during probe use.

International Classification:

A61B 8/14

US Classification:

600459

Abstract:

A wireless ultrasound probe has a probe case enclosing a transducer array, an acquisition circuit, a transceiver, a power circuit, and a rechargeable battery. The wireless probe also has a cable connector accessible from the exterior of the probe, for connection of a cable providing battery charging potential and/or imaging signal conductors for wire communication with a host system. An example is given of a magnetically attachable cable which requires no openings or indentations that could trap gel and other contaminants. Preferably the remote end of the cable uses a standardized connector, enabling the wireless probe to be recharged from standard devices like computers.

David Rust - Seattle WA, US

Assignee:

KONINKLIJKE PHILIPS ELECTRONICS N.V. - Eindhoven

International Classification:

A61B 8/14

US Classification:

600459

Abstract:

A wireless ultrasound probe has a probe case enclosing a transducer array, a probe controller, and a transceiver which wirelessly receives control signals from and transmits image signals to a host system. Mounted on the probe case is a liquid-tight user interface including basic probe user controls such as directional controls, an image freeze control, and an image save control. The user interface may be fabricated as a touchpanel LCD or OLED display. The probe may alternatively be controlled by a separate user interface which wirelessly transmits control signals to the host system or the probe. Either user interface may also include a display such as battery charge and signal strength indicators.
