Installation

  • Requires drivers provided by Telemed for running (otherwise Plus application will not start).
  • It is recommended to run the Telemed imaging software to set all imaging parameters, as Plus currently can set only a subset of all imaging parameters.

    FrameSize Maximum size of an image frame in pixels. The image is scaled so that image vertically fills the specified rectangle size, therefore if the frame size is too narrow (first component is too small) then the two sides of the image may be clipped; if the frame is too wide then there will be solid filled stripes on the left and right sides. If larger values are specified then a higher-resolution image is created.

    DepthMm Set the depth [mm] of B-mode ultrasound. If not specified (or value is <0) then the current value is kept.
