That's how first generation GE CAT scanners worked. DG Eclipse and an FPS AP-120 array processor doing convolution. Analogic and several other companies made them in the 80's. Not much documentation or software around for any of them. I supported a stripped down AP-120 called the FPS-100 on the 11/44 I supported at the Medical College of Wisconsin before I moved to California. The FPS-100 was popular with oil exploration people and MCoW picked one up cheap from a broker in Chicago when they got stuck with a bunch after the early 80's oil glut. There were a few supermini companies that had intergrated vector units by the mid 80's, then the whole thing went away as microprocessors and MPP kicked in. They were (are) also power hogs. A modern desktop CPU can blow the doors off 'em.
