Terahertz Radiation Improves Diagnostic Imaging

For medical practitioners, medical imaging, such as X-rays, CT scans, MRIs, and ultrasounds, gives distinctive viewpoints. By locating biomolecules inside specimens, spectroscopy gives more information. The goal of the research is to enhance diagnostic imaging. The researchers are creating imaging devices that use terahertz radiation after realizing the advantages of imaging and spectroscopy. Terahertz radiation has frequencies between radio and visible waves in the electromagnetic spectrum. It paves the way for quick and precise terahertz characterizations of biological samples, which may eventually aid in developing efficient cancer detection tools.

The researchers could learn more about the underlying properties of biological specimens by utilizing terahertz radiation. This understanding stems from terahertz radiation’s precise sensitivity to the biomolecular composition of cells.

Terahertz radiation has long wavelengths, which makes it a useful tool for probing biomolecules but also makes it difficult to resolve and focus in images. This most recent research provided proof that terahertz spectroscopy may provide images with a resolution that is nearly cellular in scale.

The process through which healthy cells turn into malignant is known as carcinogenesis, and the researchers want to use their discoveries in this process as well as other new areas of medical diagnosis.
