Ultrasound Spherical Lesion Phantom 408LE

Ultrasound imaging quality in three dimensions: axial, lateral and elevational

The Spherical Lesion Phantom 408 LE provides a unique way of testing resolution performance of ultrasound scanners. The Spherical Lesion Phantom contains 2 mm and 4 mm diameter tissue mimicking spherical lesions which lie in a single plane at the center of the phantom. Axial, lateral and elevational resolution are accounted for simultaneously and equally for all types of ultrasound systems and configurations. In the 2 mm section, there are 105 anechoic spheres at 0.5 cm depth intervals and in the 4 mm section there are 211 anechoic spheres at 0.75 cm depth intervals.

The Spherical Lesion Phantom 408 LE incorporates our Tissue Mimicking (TM) gel which provides a smoother background texture than conventional tissue mimmicking gels. The gel allows production of lesions with negligible echogenicity while producing no distal enhancement or shadowing inherent with other gel forms. The TM gel is also optimized for use with tissue harmonics imaging technology.

In addition, the Spherical Lesion Phantom 408 LE has a new composite film scanning surface that has improved transmission properties so more of the ultrasonic beam can be transmitted and received.

Optional accessories for the the Spherical Lesion Phantom 408 LE includes a Soft Foam-Lined Carrying Case, Rigid Case, and the Precision Ultrasound Transducer Guide.
