The Phantom Laboratory Phantomlab Spherical Magphan SMR100

Description

Magphan phantoms are designed to perform a wide range of performance evaluations of Magnetic Resonance Imaging (MRI) Scanners.

The Magphan SMR100 phantom was developed in the 1990’s, in the early days of MRI.  Our newer EMR and TMR Magphan phantoms are designed for modern MRI scanners, and we highly recommend them over the SMR100. We can, however, manufacture the 100 phantom for customers who request them.The SMR100 has a urethane sphere housing composed of two hemispherical shells with an inner diameter of 20cm. The shells are connected with a simple threaded flange connecting ring. The test cube assembly can be quickly removed without tools for greater imaging flexibility and easy access for cleaning and maintenance. The Magphan SMR100 phantoms are shipped without any fluid. Customers must fill them with appropriate MR solutions.

Test Cube: Both the cylindrical and spherical Magphan use a 10cm test cube for image quality measurements. Manufactured from 6mm-thick polycarbonate plastic the test cube has an outer diameter of 10cm. The test cube contains the slice thickness ramps, sensitometry vials, a high resolution test plate and a low contrast disk.

Configurations: The test cube plates can be assembled in the standard 2-D configuration, with dual opposed slice thickness ramps which allow operators to rapidly verify that the phantom’s z axis is precisely aligned perpendicular to the imaging plane. Nylon screws hold the unit together, allowing you to change test plates or cube sides into a 3-dimensional configuration. The 3-D configuration allows x, y, and z slice geometry measurements to be obtained from a single data acquisition.
