Positron Emission Tomography01:29

Positron Emission Tomography

4.4K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Computed Tomography

4.7K
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...

Visual System01:26

Visual System

635
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

791
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Electron Microscope Tomography and Single-particle Reconstruction01:07

Electron Microscope Tomography and Single-particle Reconstruction

2.5K
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...

    • Quantum optics
    • Human visual perception
    • Psychophysics

    Background:

    • Quantum detector tomography (QDT) is a method to characterize photon detectors.
    • It typically uses photon number states, which are difficult to produce.

    • To explore human perception of photon number states using QDT.
    • To determine the minimum number of trials required for QDT in human experiments.

    Main Methods:

    • Utilized light pulses with known Poisson photon statistics instead of difficult photon number states.
    • Developed and applied a Bayesian inference model to experimental outcomes.
    • Simulated experiments to determine feasibility and optimize parameters.

    Main Results:

    • Demonstrated that quantum detector tomography is feasible for human experiments.
    • Showed that QDT can reconstruct detector response models with as few as 5000 trials.
    • Identified optimal experimental parameters to confirm single-photon sensitivity above chance.

    Conclusions:

    • Quantum detector tomography is a viable technique for studying human visual perception at the quantum level.
    • This approach overcomes previous limitations of QDT for human studies.
    • Opens new avenues for investigating the quantum nature of human vision.
