Early in the morning, self-help machine registration No. 76 at, ------> blood sampling No. 65 ------> B on the ground floor B collar No. 20 (A5 ). I asked the aunt of B-ultrasound, saying that the blood was drawn at and B-ultrasound started at, but she suggested that I wait for the machine to get the number and then go to the blood-drawn number. Sure enough, it was not long before the machine began to iss

Abstract: full digital B-ultrasound is the development direction of ultrasound medical instruments. Its basic technical feature is to use digital hardware circuits to achieve real-time processing of ultrasonic signals with extremely large data volumes. The development direction and main signal processing technologies of full digital B-ultrasound are outlined, inc

Through a large number of literature studies, the basic steps of B-ultrasound imaging include:Beam formation, digital signal processing, and digital image processing. Digital beam synthesis is the basis for digital signal processing and imaging in the later stage. It is also the first step in the long journey. Direct image imaging is the result of beam synthesis. Digital beam synthesis usually requires basic processing technologies such as focusin

Qualcomm ultrasound 3D fingerprint scanner: Finger replacement password just around the day Sound waves are not only applicable to sound, but also very suitable for accepting your fingerprints. Maybe one day it will replace the hard-to-remember password. You can't even imagine recording your fingerprints. At present, your secure fingerprint scan is only available when your skin is in good condition. The reader may not be able to accurately retrieve

Evaluating image quality is to use some objective technical indicators to evaluate the effects of an imaging technique. In order to evaluate the quality of ultrasound images, the following parameters are generally used as the criteria for Image Quality Evaluation: (1) Details resolution: the ability to clearly distinguish regions from smaller organizations. (2) Contrast Resolution: The Contrast Resolution has two meanings: the ability to identif

The auditorium is "a place for listening". This definition implies that all aspects of space, as long as they are related to communication, should be given priority.InSound Reinforcement systemBefore the invention, a large number of people gathered in the auditorium to listen to the speaker without sound amplification speech. The auditorium uses the geometric structure of the room and the sound treatment to provide a natural sound enhancement for the

How to choose a computer speaker? Computer speakers are one of the most important external devices for multimedia computers, especially those "enthusiasts" players are at any price to buy high-quality speakers, how to buy the speaker of the desirable? Its importance indicators are mainly in the following aspects: Frequency responseThe hearing range of ordinary people's ears is the 25hz-20khz sound, theref

First, to see if the speaker is set to mute state : If the notebook is set to mute state, then the speaker will have no sound after starting boot. Suppress Mute method: Method One: 1. Click the left mouse button on the lower right corner of the screen "small horn" icon, the following figure: 2. Click on the mute "small horn" icon, the following figure: 3. At th

Most audio experts know that some rooms must have a directed speaker system, and some suggest an omnidirectional speaker system. The final choice of the system will depend on two factors: the location of the Speaker and the internal structure of the room. However, in general, the feedback is directly proportional to the Q aspect of the

When using the computer to play audio, the sound of the speaker is relatively empty, the sound field is more lax. Check the speaker's left and right channel is not reversed, you can put the two groups of audio lines swap position. If the speaker sound is lower, it is important to check the quality of the speaker, the bass
