Light blocking materials used in patient exams. (a) Light blocking fabric draped over the DBT unit. (b) Light blocking skirt surrounding the breast compression paddle. (c) Compressible light blocking foam blocks surrounding a breast phantom. (d) Foam blocks without the compression paddle on top. (e) Light blocking paper on top of the detector case. (f) Raw data acquired from a homogeneous phantom imaged through the detector case with (in red) and without (in blue) the light blocking precautions. (g) Reconstructed total hemoglobin (μM) and water (%) from the first patient imaged using the NIRST imaging components of the NIRST/DBT system.
