New methods have been developed for a variety of medical markets. The new technology makes use of electromagnetic radiation at terahertz frequencies. For those who are looking at terahertz; take a look at Terahertz technology.
Terahertz pulsed imaging, likewise referred to as TPI TM, can recognise spectral fingerprints, meaning it has the capacity to provide good contrast between different types of soft tissue. It can detect the level of water content as well as other makers of cancer. Here’s another related post; Thz nondestructive evaluation.
Patented terahertz pulsed imaging (TPI) recognises spectral fingerprints and can examine different types of soft tissue. It also provides a breakdown of the degree of water content present as well as detecting other indicators of cancer.
Digging Up Secrets About Terahertz
The system was designed to image basal cell cancer, a common form of skin cancer which is invisible to the naked eye.
Modules such as the TPI imaga 2000 have 3D 360 volumetric imaging of intact tablet coatings and cores. It has the ability to identify the thickness, distribution, coverage, and uniformity of simple and complex coatings. TPI imaga and many other modules have been utilized to study a variety of biological materials.
TPI imaging is a non-ionizing, non-destructive technique. It has lately been used in reflection geometry to uncover and categorise the terahertz properties of several organ samples freshly harvested from laboratory rats. In a short time frame, scientists were in a position to discover a number of differences between tissue types. The results concluded that TPI imaging modules can effectively differentiate between tissue types, non-invasively.
Reflectance imaging modules have the capacity to convert other modules, such as the TPS Spectra 3000, into flat bed imaging systems. Samples are posted on the unit and raster scanned using a unique, software controlled, motorised scanning table. Using other specialist imaging and data analysis software, thickness maps can be produced through collected data. This allows medical experts to detect physical features, including buried cracks, air pockets, and defects.
The primary purpose of Terahertz medical applications is cancer imaging. The modules can reveal a contrast between regions of healthy skin cells and basal cell carcinoma, a common form of skin cancer.
Recent results have shown that TPI technology can reliably distinguish between healthy and cancerous cells in excised tissue.
Terahertz medical applications have also served as for breast cancer imaging. Using light waves in a newly explored area of the electromagnetic spectrum, terahertz modules can examine breast tissue and determine whether or not removed margins are clear of cancer.
Terahertz medical imaging is much quicker compared to current examinations, as well as being reliable and effective. Histopathologic examinations can take several days, leaving the surgeon unaware whether or not the tumour has been withdrawn until well into the surgery is completed. The surgeon can analyse the tissue samples during the first procedure with terahertz applications.
Dentists can also use terahertz imaging. Terahertz rays offer a safer option to X-rays for testing teeth. Unlike X-rays, terahertz analysis reveals three-dimensional shapes by measuring how the waves are affected by the format of the target. As they’re non-ionising, terahertz rays are also thought to be safer than X-rays.
