Sometimes denoted SENSE factor or iPAT factor. PI reduction factor – this is the Reduction Factor in parallel imaging. GE and Toshiba/Canon scanners operate an overall receive bandwidth regime (kHz). In Philips scanners this is denoted “water-fat pixel shift”. Pix bw – the bandwidth per pixel in hertz (Hz). This must be a multiple of the echo spacing.Įcho spacing – the minimum echo time for fast/turbo spin echo. TR – the repetition time of the sequence in milliseconds. Phase oversampling – an additional % of phase encode steps to reduce aliassing artefact. Scan %/ phase res – the percentage of k-space (raw data) acquired. RFOV – rectangular field of view (phase FOV). Slice width (mm) – the slice width or thickness. This will change as TR, TE/echo spacing and Turbo factor ETL is changed. The maximum value is indicated in italics.

RESOLUTION CALCULATOR DOWNLOAD
You can get a free online image size calculator for your website and you don't even have to download the image size calculator - you can just copy and paste! The image size calculator exactly as you see it above is 100% free for you to use. Add a Free Image Size Calculator Widget to Your Site! Let's be honest - sometimes the best image size calculator is the one that is easy to use and doesn't require us to even know what the image size formula is in the first place! But if you want to know the exact formula for calculating image size then please check out the "Formula" box above. Some images may have the same number of pixels, but if the resolution is 72 DPI, it will print on paper much larger than if the resolution is 300. Use your image processor program to check what your image’s resolution, or dots per inch, is if you intend to print your image out. The height or width of your image in pixels is not the whole story.
This will result in pixellation if you scale it too large. Scaling an image larger will make the individual pixels of that image larger, as well. If you entered a future height or width, the percentage needed to scale to that size will be displayed. If you entered a percentage, the new height or width will be displayed. Either enter a percentage that you wish to scale the image to, or enter the final size you wish your image to be in height, width, or both.Īfter submitting your figures, your calculations will display on the screen. Enter the height and/or width of the image you need to scale.Ģ. This calculator allows you to enter the following components:ġ. This calculator is very useful for choosing just the right size to scale your image to. If you need to resize an image to a particular size, it’s important to choose the right percentage to scale your picture up or shrink it down. If you use an image that’s too small and needs to be stretched out, it will result in ugly pixellation, where the base pixels become large enough to be seen individually. If you use an image that’s too large for the space it’s in, it will result in unsightly aliasing, or jagged looking edges. That means it’s important to use the correct size if, for instance, you are scaling an image for use on a web page. Each pixel is like a building block of an image these building blocks are the base unit that make up what you see in a picture. Why Image Size is Importantĭigital images use pixels to display their content. Sizing up your image in the wrong way could lead to images not fitting the use you have for them, or images that are unattractively stretched or squeezed. Use our free online Image Size Calculator to do your image size calculations simple and easy! With so many uses possible for digital images, it’s important you get the size right.
