What is Image Scanner and its type?
Have you ever heard what this image scanner is? If this word is new to you then you must read this article. As the article ends, you may have got the information about its basics. And if you know about it then maybe you can get to know a little more about which you do not know about. By the way, after hearing the name of Image Scanner, a picture of the scanning machine definitely comes to our mind, as we have seen in the Films, where the scanning points are used in the security points to scan the body to detect any metals from it. can do. Similarly, there is another type of Scanner also called Image Scanner.
For a long time, users were asking us to write an article about it, so today I thought why should you give all the available information about what is Image Scanner. By which you will clear all the doubts of the people. Then without delay, let’s start and know what this image scanner is ? .
What is Image Scanner?
An image scanner is a digital device that is used to scan images, pictures, printed text and objects and is then converted into a digital image. Image scanners are used in a variety of domestic and industrial applications such as design, reverse engineering, orthotics, gaming and testing.
Flatbed Scanner is most commonly used in offices and homes, it is also known as Xerox machine. The modern image scanner descendants of today are the fax input devices and telegraphy equipment of earlier times. Using these Image Scanner, we can also remove photocopies, along with scanning.
History of image scanner
The first scanner was developed to be used with computers. It was a drum scanner. It was created in 1957 by the US National Bureau of Standards team. Leading the team was Russell A. Kirsch, who was working to build America’s first internally programmable (stored-program) computer, with Standards Eastern Automatic Computer (SEAC), so that he could enable Kirsch’s group The experiment can be launched by using algorithms where many new technologies such as image processing and pattern recognition.
Well many types of scanners are Mehjood, but here we will learn about some important Scanner.
1. Drum Scanners
These images scan through photomultiplier tubes (PMT). Here reflective originals are accumulated with the help of an acrylic cylinder or drum, they rotate when the object is passed in front of precision optics for scanning. These optics then transmit image information to the PMT. For Color, a drum scanner uses three PMTs by which they can read red, blue and green.
2. Flatbed Scanners
It has a glass pane and a moving optical array for charge-coupled device (CCD) scanning. Flatbeds also contain three arrays of sensors, with red, green and blue filters. Images that are scanned are placed on top of the flat pan and a dense cover is used to keep the ambient lights off. Then the sensor arrays and light source are moved to read the full image area. These are transparent images, and special accessories are used to illuminate them from the upper side.
3. Film Scanners
Slide and negative film strips are placed in a carrier within a film scanner. Here the carrier is moved with the help of a motor which uses a lens and a CCD sensor.
4. Hand Scanners
Handheld devices are pulled from the top of the image surface to scan large images.
5. 3D Scanners
These scanners depend on reference markers above the placements, which are used to align the position of the element in space.
6. Desktop Digital Camera Scanners
It’s an all-in-one printer with a desktop digital camera scanner. Here scanner offers features like high-speed image scanning.
7. Smartphone Scanner
Apps can also be downloaded in many smartphone devices, by which they are used to scan documents using digital camera exposures and finally you can take the output of those scanned images in JPEG and PDF formats.
What is CT Scan
Full form of CT scan is Computerized tomography It is also called CAT (computerized axial tomography). This is actually an X-ray process in which lots of X-ray images of any part are taken in succession. These images are then seen as a cross sectional view of internal organs. Therefore, what can not be in X-Ray can be done in CT Scan.
Where is CT Scan Used?
Using a CT scan, the entire body’s internal structures can be analyzed. Their main uses are to traumatic injuries, such as to detect a blood clot or a skull fracture, tumors, or a infection. Through this, the dark organs of the body such as liver, gallbladder, pancreas, spleen, aorta, kidneys, uterus, and ovaries can be seen.
How much is CT Scan price?
The price of CT Scan depends on many parameters. Let us know about them: –
1. Scanning location / body part
2. Contrast or Non-Contrast, what type of work you want done.
3. Slices (16/32/64 slices), how many slices do you want to do.
4. How much is that radiologist’s experience?
5. How are the commercial aspects (such as center, affiliations etc.).
Well, in a regular basis, brain CT costs around Rs 1300 / – and a full body scan or an Angio CT can cost around Rs 18000 / -.
Where most of the private hospitals and diagnostic centers charge about Rs.3000 to 5000 for a CT scan, they are less in government-run facilities, which is about Rs. Ranges from 500 to 1000. In some hospitals they are absolutely free.
How to scan
When a document is placed within the Scanner, then the image is first scanned and then it is sent to a computer system to process that scan. Scanners can read red-green-blue color from the color array and the same color is measured on the basis of their array characteristics. Image resolution is measured in pixels per inch.
How many times can CT Scan be done?
If you are talking about CT Scan then it depends on your doctor how often they want to do your scanning.
I hope I have given you complete information about what is an image scanner and I hope you all have understood about the use of the scanner.
