DCSTATS(1) DICOM PS3 - DICOM image statistics DCSTATS(1)NAME
dcstats - ACR/NEMA DICOM PS3 ... DICOM PS3 - DICOM image statistics
SYNOPSIS
dcstats [ -v|verbose ] [ -filename ]
DESCRIPTION
dcstats 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 if the pixel representation is unsigned or signed (regardless of what other attributes may specify).
The description and verbose output go to standard error.
The basic input switches are described in dcintro(1). Options specific to this program are:
-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.
-filename
Show the name of the file supplied in the arguments; a hyphen will be reported if no filename was supplied.
ENVIRONMENT EXAMPLES
% dcstats expmeta.dc3
Signed minimum value = 0x0 (0 dec)
Signed maximum value = 0x6e9 (1769 dec)
Unsigned minimum value = 0x0 (0 dec)
Unsigned maximum value = 0x6e9 (1769 dec)
Signed range = 0x6e9 (1769 dec)
Unsigned range = 0x6e9 (1769 dec)
Signed mean = 0x158 (344 dec) (19.446%)
Unsigned mean = 0x158 (344 dec) (19.446%)
Bits Stored = 16
Significant unsigned bits = 11
% dcstats impnone.dc3
Signed minimum value = 0xfa24 (64036 dec)
Signed maximum value = 0x638 (1592 dec)
Unsigned minimum value = 0x0 (0 dec)
Unsigned maximum value = 0xffff (65535 dec)
Signed range = 0xc14 (3092 dec)
Unsigned range = 0xffff (65535 dec)
Signed mean = 0xfec2 (65218 dec) (38.2277%)
Unsigned mean = 0x1cdd (7389 dec) (11.2749%)
Bits Stored = 16
Significant positive bits = 11
Significant negative bits = 11
Offset to make unsigned in hex is = 0x5dc
Offset to make unsigned in dec is = 1500

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.
