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.
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.
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. Also located inside the case are a temperature sensor and a remaining battery life monitor. In response to the sensing of an excessive temperature condition inside the probe or at the transducer array, or a low battery condition, the probe switches to a low power mode of operation. The low power mode may include energy reduction measures such as reducing r.f. transmit power (acoustic or. communication), reducing digital clock rate, reducing transducer drive voltage, and/or reducing an image scanning parameter such as frame rate, line density, or active aperture size. The probe also includes a probe inactivity sensor which switches the probe to a hibernate or sleep mode upon detection of prolonged probe inactivity.

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.
Abstract:
A system and method of three dimensional acoustic imaging for medical procedure guidance includes receiving (410) an acoustic signal that is scanned to interrogate a volume of interest; determining (430) a location of a procedural device within the interrogated volume from the acoustic signal; and displaying (470) on a display device (130) a first view of a first plane perpendicular to an orientation of the procedural device. Beneficially, a second view of at least one plane perpendicular to the first plane is also displayed. Also beneficially, a third view of a third plane perpendicular to the first plane and to the second plane is also displayed. Also beneficially, the first, second, and third views are displayed at the same time.
Abstract:
A wireless ultrasound probe is operable with a heads-up projection display system to display ultrasound images provided by the probe on glasses worn by a surgeon. This enables the surgeon to view an ultrasound image of the surgical site without averting his eyes to a display in some other area of the surgical suite and to remain focused on the patient. The image can also be transmitted to a host ultrasound system for viewing and other purposes such as image storage.
