The new crystal camera allows doctors a vision inside the body as it has not happened before

Now, scientists, led by Northwestern University and the University of Socho in China, built the first Perveskite’s first detector who can capture the individual gamma rays to photograph Spect with record accuracy. The new tool can make common types of nuclear photography more clear, faster, cheaper and safer.

For patients, this may mean the shortcomings of wiping, clearer results and fewer doses than radiation.

The study was published on August 30 in the magazine Nature Communications.

“Peruvakette is a family of crystals known as the transformation of solar energy.” “Now, they are preparing to do the same for nuclear medicine. This is the first clear evidence that Perovskite detectors can produce a kind of sharp and reliable images that doctors need to provide the best care for their patients.”

“Our approach does not only improve the performance of detectors, but may also reduce costs,” said the co -author of Yihui, a professor at the University of Socho. “This means that more hospitals and clinics can eventually enable the best photography techniques.”

Nuclear medicine, such as computer computing computing, works for individual emissions), such as an invisible camera. Doctors plant a small, safe and short -live radioskir in a specific part of the patient’s body. The gamma rays, which passes out through the tissues, emitted and eventually hit a detector outside the body. Each gamma rays like pixels of light. After collecting millions of these pixels, computers can build a 3D image for the working members.

Today, the detectors, which are manufactured by cadmium zinc (CAZT) or sodium yoli (Nai), has several disadvantages. CZT detection devices are incredibly expensive, sometimes reaching the price range from hundreds of thousands to millions of dollars for a full camera. Since CZT crystals are fragile and vulnerable to cracking, it is difficult to manufacture these revelations as well. Although CZT detection devices are cheaper, Nai detection devices produce unclear images – such as taking a picture through a blurry window.

To overcome these issues, scientists have turned into Perovskite crystals, a material that Kanatzidis has studied for more than a decade. In 2012, his collection was built for the first solar cells for the pyrofsite solid film. After that, in 2013, Kanatzidis discovered that the only Perovskite crystals were very promising to discover x -rays and gamma rays. This penetration, which was enabled by the growth of his group of high -quality individual crystals, has sparked a global increase in research and has effectively launched a new field in hard radiation detection materials.

“This work shows to what extent we can push the Peruvouskite detectors beyond the laboratory,” Kanatzenis said. “When we discovered for the first time in 2013 that individual Perovaskite crystals can discover X -rays and gamma rays, we can only imagine their capabilities. Now, we make it clear that Peruvasket detectors can reach the accuracy and sensitivity necessary for demanding applications such as nuclear medicine applications. It is exciting to see this technology approaches the influence of the real world.”

Depending on this basis, Kanatzidis led, driving crystallization, surface engineering and devices design for the new study. With the growth of these crystals and their formation carefully, the researchers created an overall pixel sensor such as pixels in the smartphone camera-providing clarity and standard stability.

He designed and developed the typical Gamma-ray detector, developed a brown camera with a camera, good-channel multi-channel reading electronics and performed high-resolution imaging experiences that achieve the capabilities of the device. Hu, Kanatzidis and their team showed that Perovskite detectors can achieve standard energy decisions and unprecedented photography performance, which paves the way for practical integration in nuclear medicine systems from the next generation.

“The design of a gamma rays and showing its performance was incredibly rewarding,” he said. “By combining high -quality pyrovskite crystals with carefully improved pixel detector and multi -channel readings system, we are able to achieve energy solution capabilities and standard photography capabilities. This work shows the real potential for the detection of the disclosure based on Perovskite to convert nuclear medicine.”

In experiments, the detector was able to distinguish between gamma rays of different energies with the best reported accuracy so far. I also felt very dims from the medical radio-99M radiochari (Technetium-99M) used in clinical practice and incredibly distinctive features, resulting in clear images that can separate small radioactive sources spaced a few millimeters away. The detector has also remained very stable, as almost every trace signal is collected without loss or distortion. Since these new discoveries are more sensitive, patients may require shorter examination or smaller doses of radiation.

NorthWestern Spinout Company Actinia Inc. Marketing this technology – it works with partners in the field of medical devices to get it out of the laboratory and to hospitals. Since it is easier to grow and use simpler ingredients, Perovskites provides a much less expensive alternative to detect CZT and Nai without sacrificing quality. Perovskite detectors also provide a realistic way to photograph using a lower dose of the radio, which can be used with a NAI detector but at a price that guarantees access to the patient on a large scale.

“The proof that Peruvakette can provide mono -photon imaging, Gamma Ray is a milestone,” he said. “It shows that these materials are ready to bypass the laboratory and to technologies that directly benefit from human health. From here, we see opportunities to improve detection devices more, increase production and explore completely new trends in medical photography.”

“High -quality nuclear medicine should not be limited to hospitals that can bear the most expensive equipment,” Kanatzenis said. “With Peruvakite, we can open the door to more clear, faster and safer checks for many patients all over the world. The ultimate goal is better checks, better diagnoses and better patient care.”
