“…The optimization of the critical imaging components and the introduction of automated optical flow algorithms into this framework ( Fig. S1) permit significantly higher spatiotemporal resolution (50 ms per tomogram at 6.6-μm voxel size and 130 ms at 1.2-μm voxel size, respectively) compared with the literature (6,10,11), while at the same time assuring 3D image sequences of suitable quality for quantitative 4D motion studies within adequate observation times.…”

“…The optimization steps lead to a reduction of the effective dose by a factor of 8 compared with the scan protocol described in ref. 11. Due to the highly parallel synchrotron radiation beam, it is sufficient to acquire radiographs for an angular range of 180 degrees to obtain the complete information required for reconstructing a tomographic volume.…”

Scientific cinematography using ultrafast optical imaging is a common tool to study motion. In opaque organisms or structures, X-ray radiography captures sequences of 2D projections to visualize morphological dynamics, but for many applications full four-dimensional (4D) spatiotemporal information is highly desirable. We introduce in vivo X-ray cine-tomography as a 4D imaging technique developed to study real-time dynamics in small living organisms with micrometer spatial resolution and subsecond time resolution. The method enables insights into the physiology of small animals by tracking the 4D morphological dynamics of minute anatomical features as demonstrated in this work by the analysis of fast-moving screw-and-nut-type weevil hip joints. The presented method can be applied to a broad range of biological specimens and biotechnological processes.

“…Due to their high-density, LSO with rare-earth dopants are competitive to other scintillating materials, such as LuAlO 3 (LuAP) perovskite or Lu 3 Al 5 O 12 (LuAG) or Gd 3 Ga 5 O 12 (GGG) garnets for X-ray imaging with submicron resolution [2,3]. Specifically, during the last few years, Tb 3+ , Ce 3+ , and Ce 3+ -Tb 3+ single crystalline films (SCFs) of LSO and YSO orthosilicates were developed using the liquid phase epitaxy (LPE) method [4][5][6][7][8] for application as scintillating screens in microimaging detectors with special resolution even in the submicron range [9,10].…”

Thermoluminescent Properties of Cerium-Doped Lu2SO5 and Y2SiO5 Single Crystalline Films Scintillators Grown from PbO-B2O3 and Bi2O3 Fluxes

In this work we show the influence of material preparation technology on the thermoluminescent properties of single crystalline films (SCFs) of Ce 3+ -doped Lu 2 SiO 5 (LSO) and Y 2 SiO 5 (YSO) orthosilicates. LSO:Ce and YSO:Ce SCFs were grown by the liquid phase epitaxy method from two different melt-solutions based on PbO-B 2 O 3 and Bi 2 O 3 fluxes. Absorption, cathodoluminescence, and thermoluminescent properties of LSO:Ce and YSO:Ce SCFs grown from the two previously mentioned types of fluxes were compared, and results of spectrally resolved thermoluminescence measurements and thermoluminescent glow curves of SCFs recorded in different spectral ranges were presented. We have found that the observed differences in thermoluminescent properties of the SCFs under study can be caused by the
