MRI-guide near infrared spectroscopic tomographic imaging system with wearable optical breast interface for breast imaging

Abstract

A new photo-detector (PD) and source fiber based wearable MRI-guide near infrared spectroscopic tomographic imaging (MRg-NIRST) system has been designed and is underdevelopment. In this new system, eight flex circuit strips, each with 6 PDs and 6 side-firing fibers will be applied to the breast, prior to coil/biopsy positioning. The intensity of the diffused light will be acquired at 48x68 source-detector positions at 12 wavelengths. The 3D optical image reconstruction will be guided through the structural information obtained from T2 MRI and the scattering properties associated with MRI defined breast density.
