Abstract: A portable ultrasound scanning system comprising a hand-held housing, ultrasound electronics of a complete ultrasound scanning system, including a beamformer and an image processing unit, contained within the hand-held housing. A first display comprises a touchscreen on the hand-held housing with a user input interface, at least partially presented on the first display. A probe containing a plurality of piezoelectric transducers is controlled by the ultrasound electronics and is connected to the housing via a cable. The ultrasound electronics are configured to receive signals from the probe and to convert those signals and provide converted signals to the first display to display a scanned ultrasound image on the first display. A second, larger, display is located remote from the housing. A connection arrangement is configured to selectively connect the second display to the ultrasound electronics, and automatically upon such connection, display the scanned image on the second display.

Abstract: A portable ultrasound scanning system for performing a diagnostic ultrasound scanning process of a patient. The system comprises a portable housing containing ultrasound electronics of a complete ultrasound scanning system including a beamformer that regulate and control operation of the scanning system. A user interface is accessible at the housing. A cable is attached at one end to the housing and at a second end has a connector. An interchangeable probe having a plurality of piezoelectric transducer elements is interchangeably coupled to the connector for transmitting electrical signals between the ultrasound electronics in the housing and the transducer elements of the interchangeable probe.

Abstract: A trans-impedance amplifier arrangement has an input configured to receive an output from a photo-detector, a current monitoring circuit configured in use to provide a current monitor signal dependent on a current through the photo-detector, and an output configured to output said current monitor signal to a control module, said output further configured to receive control information from said control module. A control module is configured to receive the current monitor signal and to provide the control information.

Abstract: A portable ultrasound scanning system for performing a diagnostic ultrasound scanning process of a patient, comprising a portable housing configured to be held in a first hand of a user of the scanning system. A display comprising a touchscreen is mounted on the hand-held housing. A user input interface, at least a part of which is presented on the display, is configured to receive inputs from a user via the touchscreen and to transmit those inputs to the ultrasound electronics. A scanning probe is configured to be held in the user's second hand. A virtual control area is included in the user interface, the virtual control area being displayed on the touchscreen of the portable housing. A trackball zone is included in the virtual control area, the trackball zone performing a navigational function using a touch-sensitive manipulation method.
