A comparison of image quality between the ScanPad transducer and software (run via the ScanX interface), and Apogee 1000 Lite.

These two comparison scans were performed on the same pregnant guinea pig, just over one week apart. In the first set of images, pregnancy can be quickly and easily confirmed on the ScanX, but the higher resolution of the Apogee system really shows in the detail and crispness of the tissue boundaries.

In this next set of images taken eleven days later, strong heartbeats can be seen with the ScanX, with the skull and spines of the pups clearly visible. The Apogee 1000 Lite really takes things up a level when it comes to detail, however; highlighting every rib, and you can even see the brain inside the fetal skull.

It’s important to also stress that both of these scanners were operating at very low power settings. You can read more about how to safely scan very small animals in this article from the Animal Ultrasound Association.
