Medical workers will eventually come across .dcm files, short for DICOM, which itself stands for Digital Imaging and Communications in Medicine. These files are read by various medical machines and software. Thereís another format, NIfTI, which is a neuroimaging format. Sadly, the two are not automatically compatible, but software like the free NIfTI to DICOM converter can convert them easily. The software may not look like much, but it can convert batches of these files in mnoments. NIfTI formats supported include .nii, .nii.gz, .nia, .img/.hdr, and .img.gz/.hdr.gz.
