The invention relates to the technical field of imaging technology, in particular to a Terahertz imaging device and a method of identifying blood vessels by adopting the Terahertz imaging device. The Terahertz imaging device comprises a support and a Terahertz wave transmitter, a Terahertz wave sensor, an image processing module and an image displaying module which are arranged on the support. Terahertz waves transmitted by the Terahertz wave transmitter are received by the Terahertz wave sensor through refection of the hand back placed under the support or the skin of other punctured parts, the Terahertz wave sensor transmits corresponding image information to the image processing module to be processed, and finally the blood vessel veins and a metal needle at a puncture position can be clearly displayed in the image displaying module. Therefore, correct puncture guidance is provided to doctors to enable the puncture to be rapid, accurate and convenient, and sufferings brought to patients due to improper puncture operation and insufficient puncture accuracy are avoided.
Description
technical field [0001] The invention relates to the field of imaging technology, in particular to a terahertz imaging device and an imaging method using the device. Background technique [0002] Terahertz wave (Terahertz, THz) is electromagnetic radiation with frequency in the range of 0.1-10THz (1THz=10 12 Hz). In the electromagnetic spectrum, terahertz waves lie between infrared and radio waves, and are located in a special area transitioning from electronics to photonics. . Compared with X-rays, terahertz photons have extremely low energy, are safe, and have no ionizing radiation; many non-polar substances are transparent to terahertz waves and have good penetration, but terahertz waves cannot penetrate water and metals. According to recent research results, terahertz waves can penetrate a few millimeters below the skin, while other existing medical technologies (such as X-rays and MRI techniques) can see through deeper tissues, but can't detect the superficial layer a...
