Contrast Enhanced Spectral Mammography Phantom (CESM) - Model 022 - Products - CIRS

a simple comprehensive phantom for routine CESM Qa

The CIRS Contrast Enhanced Spectral Mammography (CESM) Phantom is designed to address the need for QC of CEDM systems. The phantom demonstrates the presence and absence of iodine in tissues by containing different iodine concentrations and non-iodine breast tissue substitutes. The CESM phantom represents an average human breast in size and shape.

The phantom consists of four slabs. A target slab is made from breast-equivalent material in 50/50 ratio of gland and adipose tissue. The slab contains two sets of four plugs, each plug having an iodine concentration of 0.2, 0.5, 1.0 and 2.0 mg/cm². These concentrations have been chosen to cover the clinical range of iodine concentrations. A fifth plug is made of 100% glandular tissue equivalent material. This plug is positioned in the center of each plug group to mimic a glandular lesion. The contrast slab consists of half 100% adipose material and half 100% glandular material to test iodine separation from the background over a wide range of densities. The top and bottom slabs are made from 100% Adipose material and have rounded edges to mimic the realistic shape of a compressed breast.

The phantom includes a magnetic alignment fixture for easy repeatable alignment and positioning.

 

Benefits:

  • Daily and routine QC

  • Tests performance and stability of CESM

  • Contains clinically relevant iodine concentrations

  • Represents both dense and fatty breasts

  • Background provides clinically relevant challenge for target detection
