Abstract: A method for centralising the construction of images including a step of acquiring at least one radiofrequency signal with a sensor of at least one local imaging device, a step of transmitting the radiofrequency signal emanating from the sensor to the centralised processing unit, a step of processing the radiofrequency signal with a view to constructing an image, and a step of transmitting the image constructed to a display of the acquisition device. The transmission between the sensor and the processing unit and the transmission between the processing unit and the display are performed via a telecommunications network Prior to the step of transmitting to the processing unit, the radiofrequency signal emanating from the sensor is converted into a format compatible with the telecommunications network. A system for the centralised construction of images implementing such a method is described.

Abstract: Ultrasound images are rendered reproducible over long time periods by determining contours of a first image and superimposing them on a real time display screen during acquisition of a second image. The operator manipulates the probe so that the new image fits within the contours obtained from the first image. This avoids the need for signal processing requiring powerful computer resources. It also avoids the use of complicated ultrasound images. The method may be implemented in any ultrasound equipment currently available on the market.
