Biophysics Advancement of spatial resolution in dedicated breast CT UNIVERSITY OF CALIFORNIADAVIS John M. Boone GaziPeymonDedicated computed tomography of the breast (bCT) is a three dimensional imaging modality developed in order to explore its potential as an alternative to conventional, x-ray ...
Spatial resolution improved from 0.5 with a 64-slice CT to 0.4 mm with a 128-slice scanner, until 0.35 mm in a 320-slice CT scanner and 0.17 mm in 640-slice CT [44]. A basic requirement for adequate multiplanar reconstruction is that the resolution is isotropic meaning that the ...
Spatial resolution of PET scanners is lower as compared with morphological imaging techniques such as CT and MR. One of the consequences of the low‐spatial resolution is a partial loss of the signal in structures that are smaller than twice the resolution of the PET scanner, leading to measure...
Using spatial transcriptomics in human tissue at single-cell resolution (CosMx Spatial Molecular Imaging) we spatially localize each of the macrophage and neutrophil subsets identified by single-cell RNA-sequencing and unravel further macrophage diversity based on their tissue localization. Finally, single...
We use this high-resolution spatial map to characterize fundamental steps in the patterning of the midbrain–hindbrain boundary (MHB) and the developing gut tube. We uncover axes of cell differentiation that are not apparent from single-cell RNA-sequencing (scRNA-seq) data, such as early dorsal...
spatial resolution. Integrated, spatially registered single-cell maps revealed infected and uninfected plant root cell types. We observed that cortex cells exhibit distinct transcriptome profiles during different stages of colonization by AM fungi, indicating dynamic interplay between both organisms during ...

learning-based methods are deficient in terms of capturing high-frequency details and retaining edge information, so the present paper puts forth a distillation network based on the enhancement of frequency and spatial features as a means of achieving super-resolution reconstruction of medical CT ...
RNA molecules from the tissue to the slide. These RNAs were then captured by spatially barcoded primers and reverse transcribed to generate complementary DNA (cDNA), which was then subjected to sequencing. The resolution of the initial ST was 100 μm of spot diameter, with any given spot ...
MicroCT is similar to conventionalCTsystems usually employed in medical diagnoses and industrial applied research. Unlike these systems, which typically have a maximum spatial resolution of about 0.5mm, advanced microCT is capable of achieving a spatial resolution up to 0.3μm[15], i.e. about th...
