Abstract

Diffuse optical tomography for medical applications can require probes with small dimensions involving short source-detector separations. Even though this configuration is seen at first as a constraint due to the challenge of depth sensitivity, we show here that it can potentially be an asset for spatial resolution in depth. By comparing two fiber optic probes on a test object, we first show with simulations that short source-detector separations improve the spatial resolution down to a limit depth. We then confirm these results in an experimental study with a state-of-the-art setup involving a fast-gated single-photon avalanche diode allowing maximum depth sensitivity. We conclude that short source-detector separations are an option to consider for the design of probes so as to improve image quality for diffuse optical tomography in reflectance.

Figures (7)

Fig. 1
Fig. 1 Acquisition geometries: a) probe with SD = 15 mm, b) probe with SD = 10 mm. Red areas schematically depict the “banana shapes” or sensitivity matrices of the measurements between pairs used for DOT reconstructions (9 in total for each probe). For both probes, the barycenter of the central source-detector pair is aligned with the barycenter of the two inclusions along the y axis. The parallelepiped of 50 x 60 x 40 mm depicts the volume employed in the DOT reconstructions. All dimensions are in mm.

Fig. 2 Reconstructed µa maps (cut views along plane (y,z) at x = 0) for both probes at all tested depths. Black circles indicate the real position and size of the two inclusions.

Fig. 4 Reconstructed µa maps with experimental data (cut views along plane (y,z) at x = 0) for both probes at the depths of 15 and 25 mm. Black rectangles indicate the real position and size of the two inclusions.

Fig. 6 Reconstructed µa maps with experimental data (cut views along plane (y,z) at x = 0) for both probes for the depth of 15 mm for I1 (left inclusion) and 10 mm for I2 (right inclusion) on the top row and the depth of 20 mm for I1 and 15 mm for I2 on the bottom row. Black rectangles indicate the real position and size of the two inclusions.
