Electron Microscope Tomography and Single-particle Reconstruction

Electron Microscope Tomography and Single-particle Reconstruction

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Imaging Studies for Cardiovascular System III: X-Ray

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Background:

3D spine reconstruction from frontal and sagittal radiographs is challenging due to soft tissue and air cavity interference.
Accurate 3D spine models are difficult to obtain using conventional radiographic methods.

Purpose of the Study:

To develop an efficient method for accurate 3D spine reconstruction from limited radiographic data.
To overcome the limitations of current 3D spine imaging techniques.

Main Methods:

A novel algorithm combining partial information from two patient radiographs with a statistical 3D spine model.
Simultaneous iterative processes for personalized vertebra modeling (2D/3D registration) and inferring other vertebrae's shape and position.

Main Results:

The proposed approach demonstrated good performance in accuracy and robustness.
Experimental evaluations showed comparable results to CT-scans for 3D spine reconstruction.

Conclusions:

The method effectively reconstructs 3D spine models from challenging radiographic images.
This technique offers a promising alternative for accurate and robust 3D spine modeling.
