Hi,Can i reconstruct images from raw data using labview? If can, what kind of data can be used? For further clarification, im trying to get a thing called "line-data" of an image acquired from an ultrasound scanner and i want to reconstruct that image from that data using labview. Am i able to do that? However, i also need the above question answered. If any further information is needed, just tell me and i'll provide you with everything i can.Thank you for helping me.I have IMAQ, IMAQdx, Vision Module installed.

An Image is an Array of Pixels, where a Pixel can be a U8 or U16 for grey-scale images or a 32-bit value if holding RGB data. So that's the first thing you need to consider, what are your Pixels, i.e. the base data type you are using to build the image. Now, many Image arrays have sizes like 640 x 480, which is the X and Y "resolution" (how many pixels fit in the X and Y directions). Note that 640x480 is a common size for inexpensive USB Video Cameras. A minor confusion is that the corresponding LabVIEW array (say, of U8 Pixels) will have dimensions 480x640 -- this makes sense if you think "480 Rows, in the Y direction, and 640 Columns, in the X direction". So now you have your Image Array, so fill in the Pixels as you need. This will, of course, depend on what you are doing. If you are doing a "line scan" operation (which I assume means you get, say, a row of pixels at a time), you just build your 2D array from the corresponding 1D Line Scans. Here's a Demo -- it's in LabVIEW 2016, so you might not be able to copy it into your Block Diagram (unless you also have 2016), but it is simple enough that you should be able to find the functions on the IMAQ Vision Utilities Palettes (and sub-Palettes). See if you can "predict the picture" ...Bob Schor

Hi Bob,

Thanks for your concern, guess what, that's exactly me 😄
I'm a BME student and i'm studying image processing and trying to figure things out bit by bit.
The main problem of this is i don't know what a line-data means until i found the Line-profile in Vision Assistant 😄 from that, thanks for your example of 2D array, i guess i know what to do next 😄

Well, beleive me, i'm the only one around using labview for the imaging process so i'm all on my own.
