The present invention relates to an ultrasound system for performing an ultrasound measurement on a surface (2) of a body (1). The system comprising a reservoir (9) containing contact agent, an ultrasound probe (10) comprising at least one transducer element (24) for transmitting and/or receiving ultrasound waves in an ultrasound measurement area (A), at least one opening (11) for releasing the contact agent into the ultrasound measurement area (A), a contact agent delivery unit (13) for delivering a specific amount of the contact agent through the at least one opening (11), and a control unit (15) for receiving sensor information (15a) on the ultrasound measurement and for generating a control signal (15b) based on the sensor information (15a), the control unit (15) automatically controlling the contact agent delivery unit (13) based on the control signal (15b).
A 3D ultrasonic diagnostic imaging system produces 3D cardiac images at a 3D frame rate of display which is equal to the acquisition rate of a 3D image dataset. The volumetric cardiac region being imaged is sparsely sub-sampled by separated scanning beams. Spatial locations between the beams are filled in with interpolated values or interleaved with acquired data values from other 3D scanning intervals depending upon the existence of motion in the image field. A plurality of different beam scanning patterns are used, different ones of which have different spatial locations where beams are located and beams are omitted. A sequence of different beam scanline patterns may be continuously repeated, or the patterns of the sequence synchronized with the cardiac phases such that, over a sequence of N heartbeats, the same respective phase is scanned by N different scanline patterns.

An apparatus includes a plurality of photosensors. Photon trigger signals produced in response to signals from the sensors are received by a trigger line network that includes segment, intermediate), and master lines. The trigger network is configured to reduce a temporal skew introduced by the trigger line network. Validation logic provides a trigger validation output signal.
A radiation detector includes an array of detector pixels each including an array of detector cells. Each detector cell includes a photodiode biased in a breakdown region and digital circuitry coupled with the photodiode and configured to output a first digital value in a quiescent state and a second digital value responsive to photon detection by the photodiode. Digital triggering circuitry is configured to output a trigger signal indicative of a start of an integration time period responsive to a selected number of one or more of the detector cells transitioning from the first digital value to the second digital value. Readout digital circuitry accumulates a count of a number of transitions of detector cells of the array of detector cells from the first digital state to the second digital state over the integration time period.
We provide a radiotherapeutic apparatus comprising a patient support, magnetic coils disposed around the patient support for creating a magnetic field therewithin, a radiation source producing a beam of radiation directed toward the patient support and mounted on a rotatable support thereby to rotate the radiation source around the patient support, a slip ring for conveying electrical power to the radiation source and located around the patient support, including at least one electrical interruption therein. This creates a slip ring in which there is no continuous circumferential path, and one in which the current is therefore forced to take a route via one side or the other.
