User Attributes

The DICOM user attribute types are listed below.

Tag Type	Corresponding DICOM Value Representation	Description
application_entity	AE	Application Entity tags store ASCII strings up to 16 characters in length.
age_string	AS	Age String tags store a string 4 characters. nnnD nnnW nnnM nnnY The first 3 characters are a number, which may be padded with zeros on the left. The last character is “D”, “W”, “M”, or “Y”. This indicates days, weeks, months, or years.
attribute_tag	AT	Attribute Tag tags are converted to a string representing a DICOM attribute tag. A DICOM attribute tag is composed of a pair of 16-bit unsigned integers. For example: 0008\|0005. This is represented in FME as a string of characters in the format: HHHH\|hhhh where “H” are hexadecimal characters of the first value and “h” are hexadecimal characters of the second value.
code_string	CS	Code String tags store ASCII strings up to 16 characters in length.
date	DA	Date tags store a date in FME date format. YYYYMMD (Year, Month, Day) See Standard FME Date/Time Format.
decimal_string	DS	Decimal String tags store a fixed or floating point number as a string of characters. Note: The prefix “decimal” describes the type of data in contained in the string, which is in contrast to long_string and short_string tags.
datetime	DT	Datetime tags convert datetimes in DICOM to FME datetime string format. YYYYMMDDHHmmSS.mmm[(+\|-)hh:mm] (Year, Month, Day, Hour, Minute, Second, Milliseconds, optional timezone offset) See Standard FME Date/Time Format.
float	FL	Float tags store single precision floating point values.
double	FD	Double tags store double precision floating point values.
integer_string	IS	Integer String tags store negative or positive integers as a string of characters. Note: The prefix “integer” describes the type of data in contained in the string, which is in contrast to long_string and short_string tags.
long_string	LO	Long String tags are converted to UTF-8 strings up to 64 characters in length. Long String tags cannot contain newlines, nor the backslash character “\”. Note: The prefix “long” describes the length of data contained in the string, which is in contrast to decimal_string and integer_string tags.
long_text	LT	Long Text tags are converted to UTF-8 strings up to 10240 characters in length.
other_byte_string	OB	Other Byte String tags store binary-encoded strings of unlimited length.
other_double_string	OC	Other Double String tags store binary-encoded strings of unlimited length. The binary string is an array of 64-bit floating point values.
other_float_string	OF	Other Float String tags store binary-encoded strings of unlimited length. The binary string is an array of 32-bit floating point values.
other_word_string	OW	Other Word String tags store binary-encoded strings of unlimited length. The binary string is an array of 16-bit words.
person_name	PN	Person Name tags are converted to UTF-8 strings comprised of name component groups. Component groups are made up of 5 components separated by the “^” character. (FamilyNameComplex)^(GivenNameComplex)^(MiddleName)^(NamePrefix)^(NameSuffix) The first component group may be followed by its equivalent in one or more different writing systems, where each component group is separated by the equals sign “=”. Example: "Hong^Gildong=洪^吉洞=홍^길동"
short_string	SH	Short String tags are converted to UTF-8 strings up to 16 characters in length. Short String tags cannot contain newlines or the backslash character “\”. Note: The prefix “short” describes the length of data contained in the string, which is in contrast to decimal_string and integer_string tags.
signed_long	SL	Signed Long tags store 32-bit signed integer values.
signed_short	SS	Signed Short tags store 16-bit signed integer values.
short_text	ST	Short Text tags are converted to UTF-8 strings up to 1024 characters in length.
time	TM	Time tags store a time in FME time format. HHmmSS.mmm[(+\|-)hh:mm] (Hour, Minute, Second, Milliseconds,, optional timezone offset) See Standard FME Date/Time Format.
unique_identifier	UI	Unique Identifier tags store ASCII strings up to 64 characters in length. These strings are a series of numeric components separated by the period “.” character.
unsigned_long	UL	Unsigned Long tags store 32-bit unsigned integer values.
unknown	UN	Unknown tags store binary-encoded strings of unlimited length.
unsigned_short	US	Unsigned Short tags store 16-bit unsigned integer values.
unlimited_text	UT	Unlimited Text tags are converted to UTF-8 strings of unlimited length.
