"That vertical bar | is the ," she explained. "In computer terms, a pipe sends the output of one program directly into the input of another—no saving to disk, no waiting. The original .mha enters one end. A filter detects brain bleeds and tags them. The result shoots out the other end in milliseconds."
"Exactly," Alisha said. "And next time you see that error, you’ll know: somewhere, a filter is broken, and a patient is waiting." piped.mha.fl

The 3D brain reappeared—this time overlaid with a blue path for the neurosurgeon’s robotic probe. A filter detects brain bleeds and tags them
SUCCESS: Stream restored. 3D volume normalized, skull stripped, lesions mapped. Ready for surgical navigation.
She pulled up a brain scan from the MRI machine. "This is a MetaImage file , or .mha ," she said. "It’s a single, bulky file that contains two things: a short text header (pixel size, patient ID, slice thickness) and the raw 3D data of the brain. It’s like a moving box filled with glass jars—everything you need, but too heavy to ship quickly."
