Food X-ray machine, also known as RF machine x-ray unit factory, or X-ray foreign body detector. It generates X-rays through equipment, and uses X-ray penetrability to detect metallic foreign bodies mixed in products and nonmetallic foreign bodies with high density. In addition, the food X-ray machine can also carry out product defect detection, package damage detection and weight detection. Widely used in food, medicine, textile, integrated circuit board and other industries. Quality control in the food industry meets HACCP and IFS requirements, identifies product defects such as product damage, product deformation or product loss, and eliminates product quality risks. Principle of Food X-ray Machine: It mainly uses the penetration of X-ray, the collection of photoelectric technology, the integration of computer, digital signal processing and other technologies to distinguish, extract and distinguish image information through vision and pattern recognition, and finally zui realizes foreign body processing.
Not only can foreign matters in foods (such as various meat products, aquatic products, fruits and vegetables, additives, milk powder, chocolate, etc.) be detected, including metals, glass, ceramics, stones, bones, plastics, etc.; Can also identify product defects, such as packaging cracks, bubbles, content defects, etc.; Complete finished product inspection is realized.
Precautions for Use of Food X-ray Machine
1. Check whether the lock on the operating table is damaged by unauthorized persons.
2. Check that all shells of the machine have been covered, and check whether the power socket of the equipment is reliably grounded.
3. Any equipment that generates X-rays is harmful. Digital X-ray machines must be taken seriously. When the X-ray lamp is on, the types of X-ray machines and any parts of the body cannot enter the examination room.
4. Any debugging and maintenance of the machine must be operated by professional and technical personnel. Without permission, it is not allowed to modify or add any accessories and X-ray machines without permission.
5. Do not stand or sit on the conveyor belt while it is running. Do not touch the edges and rollers at both ends of the conveyor belt with your hands. When x-ray system for hospital price does not move or stops when walking, it should immediately check whether the roller and conveyor belt slip or jam, otherwise it will burn out the electric drum.
6. Please use this machine to mark the voltage. To prevent leakage, please connect the leakage protector before connecting to the power supply.
7. Water cups and food are forbidden to be placed on the console and the machine. The X-ray machine will detect that the liquid permeates into the machine and will cause short circuit.
8. When the operating environment temperature of 630mA DR x-ray system company is lower than 5 degrees Celsius, the machine shall be started up and preheated 30 minutes in advance. Water stains and ice cubes on the luggage shall be removed before the luggage passes.
9. When the machine is not used for a long time, it should be moved to a dry and ventilated place for storage.

Metal detectors use the principle of 300mA DR x-ray system manufacturer and coils through which alternating current passes to generate rapidly changing magnetic fields.  This magnetic field can induce eddy currents inside metal objects.  Eddy current will generate a mobile x ray unit company, which in turn will affect the original magnetic field, causing the detector to sound.  The accuracy and reliability of the metal detector depend on the stability of the frequency of the electromagnetic transmitter, and a working frequency of 80 to 800 kHz is generally used.  The lower the working frequency, the better the dental x-ray unit price of iron;  The higher the working frequency, the better the detection performance for high carbon steel.  The sensitivity of the detector decreases with the increase of the detection range, and the magnitude of the induced signal depends on the size of the metal particles and the conductivity.

The better x ray system for imaging center manufacturer ones cost 4,000 to 5,000 dollars.  But this basic hospital is now eliminated.  However, the dental x ray factory is still acceptable. After all, the price is very affordable and the quality is also acceptable.

For X-ray, CT, B-ultrasound, MRI, these commonly used imaging examinations, many people can not distinguish clearly. Now, Xiao Bian compares the body to food and tells you intuitively how these tests play different roles.

X-ray: It’s like squashing bread
X-rays will pass through the human body and will not be exposed on the negative when they encounter the blocked part. After the film is developed, this part will be white. Like a piece of bread or a piece of cotton, you can’t see the fiber texture inside, but it will be clearer if you press it down with your hand. The biggest disadvantage of X-ray is that the images of deep and shallow tissues overlap and hide from each other, which sometimes requires multiple multi-angle X-ray films.

CT: Look like slicing bread
The principle of CT examination is that X-rays pass through the human body in layers, and then are computed by a computer for secondary imaging, just like cutting a piece of bread into slices. The advantage is that it can be seen in layers and more organizational information can be displayed after calculation.

B ultrasound: like picking watermelons, knock before picking them.
The principle of B-ultrasound is to use ultrasonic waves to penetrate the human body. When the sound waves meet the human body tissue, they will generate reflected waves, which are imaged by calculation. Just like picking watermelons, one needs to knock first before judging the situation.

Nuclear Magnetic Resonance: Shake and See
The magnetic resonance machine uses a relatively strong magnetic field to make the magnetic field lines of all water molecules in the human body in the same direction. At this moment, the magnetic field of the magnetic resonance machine suddenly disappears, and the magnetic field lines of water molecules in the human body suddenly return to the original randomly arranged state. Repeated application of magnetic field suddenly disappeared, and the MRI opportunity obtained sufficient data and imaged after calculation. Simply put, it is equivalent to shaking the water molecules by hand, making them vibrate, then calm down and feel the vibration inside. Therefore, magnetic resonance imaging (MRI) is also said to be a “shaking examination”.

What kind of examination are the four imaging methods applied to? When seeing a doctor, doctors often issue various imaging checkups: ultrasound, CT, MRI … Many patients will question the doctor’s intention to issue expensive checkups. In fact, doctors choose different imaging examinations according to different conditions.

1. Traumatic bone-Take a rough look at the X-ray film and examine various CT traumas. If you suspect that a bone has been injured, give priority to the X-ray film. The examination results are quick and easy to obtain. For further observation, CT can be selected. Ultrasound and nuclear magnetic resonance can’t clearly see the bone cortex and medulla, so they are generally not selected.

2. Cervical vertebra and lumbar vertebra-MRI is the best choice, CT is the second choice, cervical spondylosis, lumbar intervertebral disc herniation and other diseases need to observe intervertebral disc and corresponding nerve roots. To better observe these soft tissues, MRI is the best choice. Similarly, MRI is also the first choice for joint, muscle and adipose tissue examination.

3. Chest-A rough look at the X-ray film and a close look at the CT X-ray film can roughly check the heart, aorta, lung, pleura, ribs, etc. It can also check for increased lung texture, pulmonary calcification, aortic calcification, etc. Chest CT examination shows a clearer structure, and its sensitivity and accuracy in detecting chest lesions are better than conventional chest X-ray films, especially for the early diagnosis of lung cancer. However, the radiation dose of CT examination is higher than that of X-ray. Nuclear magnetic resonance is very limited in the diagnosis of lung diseases.

4. Abdominal Pelvic Cavity-Except intestinal tract, general ultrasound can check that abdominal organs are greatly affected by respiration, thus affecting CT and MRI, while ultrasound will not be affected. At the same time, ultrasound has high diagnostic accuracy for liver, spleen, pancreas, kidney, pelvic organs, etc. However, ultrasound is greatly disturbed by gas. For organs with more gas, such as intestinal tract, the accuracy of ultrasound diagnosis will decrease.

5. Heart-CT is used to exclude coronary heart disease, and conventional cardiac structure and function examination is used to check cardiac function. The information provided by cardiac color Doppler ultrasound is sufficient and simple. Coronary artery can be examined by CT, but coronary artery CT examination has a large amount of radiation and is not suitable for routine physical examination. Although nuclear magnetic resonance has no electromagnetic radiation, the observation of coronary artery is not as good as CT. Cardiac MRI is the “gold standard” for evaluating the structure and function of the heart.
