VHI FILE SPECIFIERS

Introduction

File specifiers are file names used as machine readable record identifier. File specifiers are identified for database output image records, database imported knowledge frame files, and database imported binary mask files. Fields listed for each file specifier are based on the prototype image database, and maybe expanded in future use.

Output image records have file specifiers consist of twelve characters and a VHI suffix. Each character is defined below in the image record specifier. Note that cross section image records differ in the last seven characters from those of anatomical structures with UMLS identifiers.

Imported segmented image data consists of a knowledge frame file (KFF) and a segmented binary bitmask (SBB). Knowledge frame file specifiers consist of twelve characters and a KFF suffix. Each character is defined below in the KFF specifier. Segmented binary bitmask specifiers consists of twelve characters and a SBB suffix. Each character is defined below in the SBB specifier.

Imported rendered image data consists of a knowledge frame file and a rendered image file. Rendered image file names and file format are defined by the media producer. This information is identified in the knowledge frame file.
