What does the bus mean in the physical examination?

Bus detection is actually BULTRASOUND, B-type ultrasonic detection, referred to as B-ultrasound.

Ultrasound has many forms in disease diagnosis:

① Diagnosis of diseases in the form of amplitude is called "one-dimensional display". Because the first English letter of amplitude is a, it is called a-ultrasonic, also known as one-dimensional A-ultrasound.

② It is called "two-dimensional display" to diagnose diseases in the form of brightness mode. Because the first English letter of brightness is B, it is called B-ultrasound, also called two-dimensional ultrasound or gray-scale ultrasound.

Ultrasonic endoscope probe enters the body for B-ultrasound examination.

The reporter learned from Suzhou Institute of Medical Engineering of China Academy of Sciences that the team led by Cui Song, a researcher in the Medical Acoustics Room of the Institute, has recently developed an ultrasonic endoscope microprobe suitable for the examination of digestive tract and intestinal diseases. This new instrument can better image the lesions, so that doctors can more accurately identify the stages of digestive tract tumors and make treatment plans.

At present, the new probe has been produced in small batches and is expected to enter the product registration stage within two years.

Ultrasonic endoscope is a technology that uses ultrasonic waves to image the inner cavity of human body. A miniature high-frequency ultrasonic probe is placed at the front end of the interventional catheter and inserted into esophagus, gastrointestinal tract and bronchus for real-time scanning and imaging.

The core component of the endoscope microprobe developed this time is an ultrasonic transducer the size of a grain of rice. The latest imaging test shows that this transducer can clearly see the five-layer structure of the stomach wall and meet the clinical needs.

By using ultrasonic endoscope, doctors can clearly distinguish the growth level and infiltration depth of tumors. In addition, the ultrasonic endoscope can also be applied to the imaging of organs near the intestine and play a role in the diagnosis of pancreatic, bile duct and gallbladder diseases.

Cui Wei introduced that compared with traditional optical endoscopy or X-ray imaging, the information obtained by ultrasonic endoscopy is much richer, and it is more convenient and safer than puncture examination.

"For example, the traditional gastrointestinal endoscope is equivalent to' looking in the mirror' for the gastrointestinal tract, and only the surface of the inner wall of the organ can be seen, while the ultrasonic endoscope is equivalent to inserting the probe into the body for B-ultrasound." Cui Wei said, "With the improvement of technology, images with higher resolution and deeper penetration can be obtained in the future, helping surgeons to better prescribe the right medicine or adopt better surgical strategies."

Health news-the probe of ultrasonic endoscope pierces into the body to do B-ultrasound.
