Based on the alpha particles released during the decay process, radionuclides can be identified and quantified using alpha spectroscopy.
Energy spectra are produced using high precision alpha particle detectors and electronics and evaluated using specialised software, much like gamma spectroscopy.
One can observe the detection of alpha particles with the Images Alpha Particle Spark Detector. It serves as an example of radioactive alpha particle electronic detection.
In addition, the shielding of radioactive particles by an absorber can be demonstrated using a blank piece of paper. The use of alpha emitter radiation therapy in the treatment of prostate cancer that has metastasized to the bone is now under investigation.
A doubly ionised helium atom, which has an atomic mass of four, is equivalent to the nucleus of an alpha particle. The first type of nuclear radiation to be recognised was alpha particles, often known as alpha radiation or alpha rays. Beta particles and gamma rays followed shortly after.
The global Alpha radiation detector market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Launch of the first photon-counting CT scanner in the world by Siemens Healthineers, Naeotom Alpha. The system has currently received approval for clinical usage in the USA and Europe.
Technically speaking, conventional CT imaging has reached its limits. Only slight improvements in resolution are possible, and dose cannot be greatly decreased.
Using photon counting, significant advancements are possible. For ultra-high resolution (UHR) scans, these enhancements include an increase in resolution and a radiation dose reduction of up to 45% when compared to standard CT detectors without a UHR comb filter.
With traditional detectors, this would not be possible. Because photon-counting technology immediately detects each X-ray photon and its energy level rather than first transforming it into visible light as with conventional CT imaging, photon-counting scans have more useful data.
These factors work together to create new capabilities, such as the ability to scan a patient’s lung quickly and obtain high-resolution images with spectral information without requiring the patient to hold their breath.
In the event that certain elements inside the body hinder a region of interest, they can even be erased from the image with the use of this spectral information. This enables doctors to diagnose problems rapidly and offers the chance to begin therapy right away.
