Ultrasound imaging for veterinarians/Livestock

Ultrasounds are used since 1970’s for medical imaging.  Since, echographic techniques have been developed for clinician veterinarians and for animal production.

UNGAVA proposes a product range for applications in animal production, especially for swine, bovine, ovine and equine production. UNGAVA is noted for its high performance products with an unequalled manufacturing quality.   UNGAVA's products are built for field requirements.

There are 2 types of echograph for animal production:

Mechanical Sector Probe:

a probe contains only one piezoelectric crystal, but this one does a back-and-forth move with a motor to scan a sectorial zone.  The instrument controls the motor and its scan, therefore produce a sector scan (pie slice) on the screen.  This image will be the representation of the echos depending on the propagation time, for each angle (beam) covered in the scan.  Typical scans are from -45 to +45 degrees.   Mechanical sector probe instruments are cheaper because the image is less clear.

Electronical Scan Probe:

a probe contains many juxtaposed miniature piezoelectrics crystals that are driven by the instrument.  The instrument controls the activation, but also the transmission and reception phase of each crystal.  Therefore, it can create a precise ultrasonic wave and the image is much clearer, since we have better control over focusing.

To create a linear image, the instrument activates a group of crystals and changes the activation pattern laterally change the wave.  The created image is a rectangular scan.

To get a sector scan, the instrument activates a group of crystals and changes the phasing pattern phase to change the wave angle.  The created image is a sector scan.
