Accurate approach to capillary-supported optical diffraction tomography

Abstract: A new holographic data processing path for accurate quantitative tomographic reconstruction of 3D samples placed in a cylindrical capillary is proposed. The method considers strong unintentional focusing effects induced by the inner cylindrical boundary of the vessel: 1) introduction of cylindrical wave illumination of a sample, and 2) object wave deformation. The first issue is addressed by developing an arbitrary illumination tomographic reconstruction algorithm based on filtered backpropagation, while the s… Show more

“…Mechanical rotation of samples, however, limits data acquisition speed. Also, perturbation occurred during mechanical rotation, called radial run-out [32], and field distortion due to the refraction from the cylindrical microcapillary require additional numerical correcting algorithms [33]. More importantly, the sample rotation method can cause deformation of live biological cells because of the viscoelasticity of cells, possibly resulting in artifacts in reconstructed tomograms.…”

“…The high potential of HT is widely appreciated in life sciences and biomedicine, where it is used for minimally invasive 3D imaging of unstained, living, cellular specimens [1][2][3][4][5]. However, to enable the study of sensitive biological materials, originally proposed HT technique applying the object rotation configuration (ORC) [2,[5][6][7][8][9][10] had to be modified to minimize the risk of damaging a sample. Currently, with a few exceptions [5][6][7], the biomedical-oriented HT systems utilize a tomographic concept in which physical manipulation of a sample is completely eliminated.…”

“…However, to enable the study of sensitive biological materials, originally proposed HT technique applying the object rotation configuration (ORC) [2,[5][6][7][8][9][10] had to be modified to minimize the risk of damaging a sample. Currently, with a few exceptions [5][6][7], the biomedical-oriented HT systems utilize a tomographic concept in which physical manipulation of a sample is completely eliminated. In those systems different sample projections are achieved by scanning an illumination beam, while keeping a sample and a detector fixed [1][2][3][4].…”

“…Moreover, relatively long data acquisition time prohibits application of ORC-HT to investigation of dynamic processes. Lastly, the ORC systems require direct [1][2][3] or indirect [5,14,15] physical manipulation of a specimen, which poses a risk of disturbing or even damaging a sample. These issues are particularly troublesome for biomedical-oriented studies, especially for investigation of living biological specimens.…”
