Using High Resolution Computed Tomography to Visualize the Three Dimensional Structure and Function of Plant Vasculature

High resolution x-ray computed tomography (HRCT) is a non-destructive diagnostic imaging technique that can be used to study the structure and function of plant vasculature in 3D. We demonstrate how HRCT facilitates exploration of xylem networks across a wide range of plant tissues and...

Computed Tomography01:10

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...

Identifying Coronary Artery Calcification on Non-gated Computed Tomography Scans

Here, we present a protocol to reliably and systematically identify coronary artery calcification (CAC) on non-gated computed tomography (CT) scans of the chest or abdomen. CAC provides an objective measure of coronary artery disease for both research and clinical...

Single Photon Emission Computed Tomography for Assessing Brain Function Disruption01:00

Single Photon Emission Computed Tomography for Assessing Brain Function Disruption

A traumatic brain injury, or TBI, impairs blood flow to the impacted regions and disrupts the activity of dopaminergic neurons.To investigate TBI-associated disruptions, begin by intravenously injecting a lipophilic radioactive tracer into a patient.The tracer travels through the cerebral vessels and diffuses into cells of the cortical and subcortical brain tissue.Perform single photon emission computed tomography, or SPECT, to detect the tracer-emitted radiation. The resulting signal intensity...
