Light and sound -powered non -Vasio Stent Imaging

In a new study, researchers show, for the first time, they can make a picture of stents through photo coostic microscopy skin, which offers a safe, easy way to monitor these life -saving devices. Each year, in the United States, about 2 million people are applied to Stunt to improve blood flow to tight or blocked arteries.

“It is important to monitor the stent for issues such as fracture or wrong positioning,” said researcher Mewongsu Saving, a co -leader researcher from Xiaz Jiayott Liverpool University in China, but traditionally used techniques require an unpleasant procedure or radiation display. ” “It encouraged us to test the ability to use photo coostatic imaging to monitor the stent through skin.”

In the journal Optics letterResearchers find that photocastic microscopy can be used to view the mouse -covered stunts under various medical conditions, including artificial damage and plaque construction.

Without the need for surgery access or X -ray exposure in China, the results of our photo coostatic microscopy are preliminary, but further development can enable the stent status, non -visual monitoring. “” This will make it easier and safe to monitor the condition of the stent in patients. “

The use of sound to see the stent

Photo Coastic Imaging is a label -free technique that detects sound waves that arise to absorb light and release energy. Since the sound is less scattered than light, the method of imaging can be used to achieve high resolution images over the depths of pure optical methods.

Although other studies have been used photocostatic imaging to image stunt by endoscope, it is still important that the patient goes through a procedure. In a new study, researchers examined whether the photo -coostatic microscopy would enable non -Vioceive Steant Monitoring through skin.

To do so, they imitated various stunt scenes, including fractures, compression and the movement of overlaps. They also used butter to imitate the plaque or blood clots after stenting. Using photo coostic microscopy on various wavelengths, including 670 nm and 1210 nm, they managed to portray these different stent conditions through the mouse skin.

“One of the most interesting consequences is that we can easily distinguish the butter that we used to imitate the lipid plaque and the stent,” said Saving. “Because plaque and stent absorbs light in different ways, using two wavelengths helped us to distinguish them.”

Molding for depth

Researchers say that photo coostic microscopy can potentially be used to create a stunt image in places accessing dialysis, which is usually located under the skin. For stent in deep areas like caroted artery, a related method called photo coostic computate tomography can be more suitable.

Researchers said that clinical Nanovsu can be used for Stent Stanton Monitoring before photocostic imaging, Vivo will have to do the animal experiments and make early medical experiments. The system will also need to improve the OPTim to use in different parts of the body.
