Optical devices for use with a magnetic resonance imaging breast compression system include light wands and optical adapters that can releasably mate with grids. These devices, and their associated methods, may reduce or eliminate the need for biopsy by allowing for the differentiation of cancerous tumors, non-cancerous tumors, calcifications and cysts.

Devices and methods for combined optical and magnetic resonance imaging

Optical tomography systems that provide light of multiple distinct wavelengths from a plurality of sources are described. The systems direct light into mammalian tissue, and light from the mammalian tissue is collected at a plurality of reception points. Collected light from each reception point is separated according to its wavelength, and received by a photodetector to produce path attenuation signals representing attenuation along paths between the source locations and the reception points. An image construction system generates a tomographic image of the mammalian tissue from the path attenuation signals. One embodiment of an optical imaging system includes an optical coherence tomography-near infrared probe. The systems and methods may utilize a spectral derivative approach that provides insensitivity to the boundary and boundary artifacts in the signal, thereby improving the quality of the reconstructed images.
