ANDUMP(1)					    DICOM PS3 - Describe ACR-NEMA file content						 ANDUMP(1)

NAME
andump - ACR/NEMA DICOM PS3 ... Describe ACR-NEMA file content SYNOPSIS
andump [ -ancreate ] [ -extractCSA ] [ -showoffset|-showoffset-hex |-showoffset-octal|-showoffset-oct |-showoffset-decimal|-showoffset-dec ] [ -filename ] DESCRIPTION
andump reads the named acr-nema input file and describes the information contained, without attempting to interpret the structure of the message (cf. dcdump). The group and element number, dictionary and explicit value representation, description of tag, value length and value of the element are displayed, optionally with an offset byte count from the start of the file. OPTIONS
The attribute values, description and verbose output go to standard error. Binary attributes are written in hexadecimal with a preceding "0x". Numeric string attributes are written in decimal. Attribute values are displayed in hexadecimal or string format as determined by the value representation. The basic input switches are described in dcintro(1). Options specific to this program are: -ancreate Display item, end item and end sequence delimiter tags in a form suitable to feed into ancreate. -extractCSA Extract the DICOM-like attributes buried within the Siemens private CSA header OB value. -showoffset|-showoffset-hex Display byte offset from file start in hexadecimal. -showoffset-octal|-showoffset-oct Display byte offset from file start in octal. -showoffset-decimal|-showoffset-dec Display byte offset from file start in decimal. -filename Show the name of the file supplied in the arguments; a hyphen will be reported if no filename was supplied. ENVIRONMENT

DCHIST(1)						DICOM PS3 - DICOM image statistics						 DCHIST(1)

NAME
dchist - ACR/NEMA DICOM PS3 ... DICOM PS3 - DICOM image statistics SYNOPSIS
dchist [ -h|histogram ] [ -csv ] [ -withhighbits|highbitsonly ] [ -v|verbose ] [ -filename ] DESCRIPTION
dchist reads the named dicom or acr-nema input file and describes the statistics of the image pixel data. The primary intent is to deter- mine the zero order entropy of the image. The description and verbose output go to standard error. The basic input switches are described in dcintro(1). Options specific to this program are: -h|histogram Display table of pixel value, frequency, probability, contribution to zero order entropy, and cumulative zero order entropy. May generate a LOT of output ! -csv Display only a comma separated value pair of pixel value and frequency, one line per value, e.g., for import into a statistical pro- gram or spreadsheet -withhighbits Include as well the values that are above Bits Stored and within Bits Allocated, such as might be overlay bits (regardless of whether or not there are any 60xx group elements). -highbitsonly Use instead the values that are above Bits Stored and within Bits Allocated, such as might be overlay bits, and treat all valid pixel values below Bits Stored inclusive as zero (regardless of whether or not there are any 60xx group elements). -v|verbose Display byte offset from file start and message start, in hexadecimal, and dump contents while reading and once read. -filename Show the name of the file supplied in the arguments; a hyphen will be reported if no filename was supplied. ENVIRONMENT
EXAMPLES
% dchist expmeta.dc3 9.02366 Zero order entropy (bits per pixel) 0x0 Smallest symbol value 0 Smallest symbol length (bits) 0x6e9 Largest symbol value 11 Largest symbol length (bits) % dchist -h expmeta.dc3 [0x0] 392 p=0.00598145 e=0.0441747 cum=0.0441747 ...
