The beginning and end values for Range Matching of date and time Key Attributes. See Section C.38.2.1.1.3.
Exactly two Items shall be included in this Sequence.
Required if Range Matching is applied to any Key Attribute.
Range Matching Sequence (0008,0410) provides values for Key Attributes that use range matching of dates and times using the mechanism specified in Section C.2.2.2.5 “Range Matching” in PS3.4.
The same set of Key Attributes shall be present in both Items of this Sequence. For each Key Attribute, at least one Item shall have a non-zero length value.
Values in the first Item represent the beginning of the range, and values in the second Itemrepresent the end of the range. If the first or the second value is empty, the range has an unbounded beginning or end, respectively. The range is inclusive; matched Attributes whose value is at or after the first value and before or at the second value match the range.
In the equivalent Query/Retrieve Service Class range matching, the beginning and end values are encoded in a single Data Element, and delimited by "-".
If Extended Matching Mechanisms (0008,040F) includes the value COMBINED_DT, related date and time Attributes, such as Study Date (0008,0020) and Study Time (0008,0030), are considered together as a datetime value for matching.
If Extended Matching Mechanisms (0008,040F) includes the value TIMEZONE_ADJUST, dates and times are adjusted for the local timezone specified in Timezone Offset from UTC (0008,0201), as specified in Section C.2.2.2.1.3 “Attributes of VR of DA, DT or TM” in PS3.4.
