Technology Overview: Principles of Backscatter Tomographic Bioluminescence Imaging
Backscatter Tomographic Bioluminescence Imaging (BTBI) represents a sophisticated evolution of bioluminescence imaging (BLI), designed to overcome the inherent limitations of conventional planar BLI in small animal and preclinical research. While standard BLI provides high sensitivity for monitoring gene expression and cellular events in vivo, its utility is often hampered by poor spatial resolution and limited depth localization, due to photon scattering and absorption in biological tissues. BTBI addresses these challenges by integrating tomographic reconstruction algorithms with advanced photon detection strategies, focusing on the analysis of backscattered light to yield three-dimensional (3D) images of internal bioluminescent sources.
The core principle of BTBI lies in its exploitation of backscattered photons—those emitted from bioluminescent sources within tissue and scattered back toward the surface detectors. By acquiring emission data from multiple surface locations and directions around the subject, BTBI employs computational algorithms to reconstruct the 3D distribution of the bioluminescent signal. This process typically involves solving an inverse problem, using models of light propagation (such as the diffusion approximation to the radiative transfer equation) that account for tissue-specific optical properties.
Recent years have seen rapid progress in the components underpinning BTBI systems. Notably, the introduction of high-sensitivity cooled charge-coupled device (CCD) cameras and complementary metal-oxide-semiconductor (CMOS) detectors has significantly improved the detection of weak bioluminescent signals, even in the presence of considerable background noise. Key manufacturers such as Hamamatsu Photonics and Princeton Instruments continue to advance low-light imaging technologies crucial for BTBI platforms.
On the software side, the integration of robust tomographic reconstruction algorithms—including algebraic reconstruction techniques and maximum likelihood estimation methods—enables more accurate mapping of light sources deep within tissue.
