The Problem: 

Physicians, treating a patient with a brain aneurysm, often use a device such as the Medtronic Pipeline TM device. The physician must size the device prior to implant by integrating a series of 2D images to mentally reconstruct the relevant 3D anatomy. As a result, clinically significant information is often lost, especially when tracing tortuous anatomy on 2D planes.

Case Studies:

In a published article, physicians retrospectively evaluated two cases to verify accuracy and precision of EchoPixel’s True 3D measurements to assist them in sizing Medtronic Pipeline TM vs. their current 2.5D2 solution. The researchers found large discrepancies between the measurements they made using the visual information from their current 2.5D solution and the implanted device size. In some cases, these differences were > 5mm. The measurements they made using the EchoPixel system were overall more precise and accurate. In one acute case, based on the calculations they made using EchoPixel information, physicians changed their 2.5D derived suggested device size from 11mm to 15mm. Had they used the 11mm device they would have needed to subsequently remove it and implant the 15mm.
