Positron Emission Tomography01:29

Positron Emission Tomography

6.2K
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...

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)01:15

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)

1.2K
Insensitive Nuclei Enhanced by Polarization Transfer (INEPT) is an advanced Nuclear Magnetic Resonance (NMR) technique specifically designed to detect and enhance the signals of low-abundance nuclei, such as carbon-13 and nitrogen-15, in small molecules. The fundamental principle behind INEPT is the transfer of polarization from a more abundant and highly polarizable nucleus, typically hydrogen-1, to the low-abundance nucleus of interest. This process effectively boosts the NMR signal of the...

Inductively Coupled Plasma–Mass Spectrometry (ICP–MS): Overview01:19

Inductively Coupled Plasma–Mass Spectrometry (ICP–MS): Overview

2.7K
In inductively coupled plasma–mass spectrometry (ICP–MS), an inductively coupled plasma (ICP) torch is used as an atomizer and ionizer. Solid samples are dissolved and volatilized before being introduced into the high-temperature argon plasma, while solution samples are nebulized and passed through the high-temperature argon plasma. Plasma dissociates the analytes and ionizes their component atoms to form a mixture of positive ions and molecular species. The positive ions are then...

Ionization Energy03:12

Ionization Energy

32.6K
The amount of energy required to remove the most loosely bound electron from a gaseous atom in its ground state is called its first ionization energy (IE1). The first ionization energy for an element, X, is the energy required to form a cation with 1+ charge:

Isotopes and Radioisotopes01:28

Isotopes and Radioisotopes

10.5K
In the early 1900s, English chemist Frederick Soddy realized that an element could have atoms with different masses that were chemically indistinguishable. These different types are called isotopes — atoms of the same element that differ in mass. Isotopes differ in mass because they have different numbers of neutrons but are chemically identical because they have the same number of protons. Soddy was awarded the Nobel Prize in Chemistry in 1921 for this discovery.
An isotope containing...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation01:26

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

1.1K
Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy  (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used....

    Area of Science:

    • Medical Physics
    • Radiation Oncology

    Context:

    • Proton therapy requires precise alignment of radiation and mechanical isocenters for accurate dose delivery.
    • Conventional isocenter verification methods involve multiple devices and measurements, potentially reducing accuracy and efficiency.

    Purpose:

    • To develop and evaluate a novel isocenter verification device for proton therapy equipment.
    • To assess the device's ability to correlate multiple isocenters in a single measurement for improved accuracy.
    • To investigate the reproducibility and long-term stability of isocenter positions using the developed device.

    Summary:

    • A new device was developed to simultaneously verify radiation and mechanical isocenters for proton therapy equipment, including room lasers, digital radiography, and rotational gantry beam axes.
    • The device demonstrated improved accuracy by correlating three isocenters in one measurement compared to separate conventional methods.
    • Annual monitoring of two gantries showed isocenter position fluctuations within +/-0.18 mm, with a measurement repeatability of +/-0.18 mm or less.

    Impact:

    • Enables more accurate and efficient quality control in proton therapy through a consolidated verification process.
    • Reduces verification time to approximately 30 minutes, allowing for quality checks post-clinical practice.
    • Contributes to enhanced patient safety and treatment efficacy in proton therapy by ensuring precise beam targeting.
