ImageJ can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit pictures, and supports various formats such as TIFF, PNG, GIF, JPEG, BMP, DICOM and FITS.
Extended data:
DICOM is widely used in radiotherapy, cardiovascular imaging and diagnostic equipment for radiotherapy (X-ray, CT, nuclear magnetic resonance, ultrasound, etc. ), and has been more and more widely used in ophthalmology, dentistry and other medical fields. DICOM is one of the most widely deployed medical information standards among thousands of medical imaging devices in use. At present, there are about tens of billions of medical images that meet DICOM standards in clinical use.
DICOM files are composed of different data elements. These DICOM images cannot be directly converted into JPEG or BMP images, and the information will be lost. The value range of each channel of common images is 0-255. The words of CT are gray images, and the range of each pixel is at least one or two thousand. So this kind of image can be viewed by ImageJ software. ImageJ can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit pictures, and supports various formats such as TIFF, PNG, GIF, JPEG, BMP, DICOM and FITS.
ImageJ supports image stacking function, that is, multiple images are stacked in a window in the form of multithreading and processed in parallel. ImageJ can open as many images as memory allows. In addition to basic image operations, such as scaling, rotation, distortion and smoothing, ImageJ can also count the area and pixels of a picture, calculate the distance and angle, create histograms and contours, and perform Fourier transform.
