Telemed USB ultrasound systems

Supported hardware devices

This device is used for image acquisition from Telemed ultrasound systems.
Tested only with MicrUs devices (http://www.pcultrasound.com/products/micrus/index.html) but other Telemed devices should be compatible, too.

Supported platforms

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.

Device configuration settings

Type: TelemedVideo
AcquisitionRate: (Optional, default: 30)
LocalTimeOffsetSec: (Optional, default: 0)
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. (Optional, default: 512 512)
DepthMm: Set the depth [mm] of B-mode ultrasound. If not specified (or value is <0) then the current value is kept.
FrequencyMhz: Ultrasound transmitter frequency. If not specified (or value is <0) then the current value is kept. [MHz].
DynRangeDb: Dynamic Range [dB] of B-mode ultrasound. If not specified (or value is <0) then the current value is kept.
GainPercent: Is the gain percentage of B-mode ultrasound. If not specified (or value is <0) then the current value is kept. Valid range: 0-100.
PowerPercent: Power to be used for imaging, as a percentage of maximum available power. If not specified (or value is <0) then the current value is kept. Valid range is 0-100.
DataSources: Exactly one DataSource child element is required (Required)
- DataSource: (Required)
  - PortUsImageOrientation: (Required)
  - BufferSize: (Optional, default: 150)
  - AveragedItemsForFiltering: (Optional, default: 20)
  - ClipRectangleOrigin: (Optional, default: 0 0 0)
  - ClipRectangleSize: (Optional, default: 0 0 0)
