New Zealand researchers have developed a new type of medical scanner and used it to generate three-dimensional color X-ray images of the human body, which is the first time in the world. This new device can provide a clearer and more accurate image of the inside of the human body than traditional black and white C-rays, helping doctors diagnose diseases.
Researchers at the University of Otago and the University of Canterbury, New Zealand, spent nearly 10 years developing the scanner using the Medipix chip technology developed by the European Nuclear Research Center for the Large Hadron Collider.
According to the CERN website, Medipix is ​​a chip for particle imaging and inspection that works like a digital camera sensor. When the electronic shutter is opened, the chip can detect and count individual particles striking the pixel, resulting in a "high resolution, high contrast, very reliable" image, especially for medical imaging.
The new scanner uses this chip as the core to detect the wavelength changes of X-rays passing through different substances in the human body. Combined with spectral information and specific algorithms, it can generate three-dimensional color that clearly distinguishes muscle, bone, water, fat and disease markers. Image for easy viewing of various body tissue details.
Phil Butler, a professor at Canterbury University who is involved in research and development, said: "This technology makes the machine unique in its diagnosis. Small pixels and precise energy resolution mean that this new imaging tool can be made impossible by other devices. Image. This is like upgrading from black and white film to color photo, it is a brand new X-ray experience."
Researchers are currently experimenting with cancer, bone and joint health and cardiovascular disease using a new scanner, and the next step is to conduct clinical trials in orthopedic and rheumatic patients. The new device is expected to help doctors make more accurate diagnoses and develop more personalized treatment plans, including for targeted drug research and minimally invasive surgery.
The researchers said that the previous research was based on the metabolic mechanism of insects, and the utilization of plant energy by dinosaurs and insects may be very different, so the new experiments they carried out were inconsistent with previous studies.
