Value RepresentationLong Text (LT)

String of 0's (no treatment) and 1's (treatment) describing the intended start fraction for this set. Length of string is 7 x Number of Fraction Pattern Digits Per Day x Repeat Fraction Cycle Length. The first character of the string represents Monday.

See Section C.36.2.1.1.1.2.

Section C.36.2.1.1.1.2

C.36.2.1.1.1.2 Intended Start Day of Week

The Intended Start Day of Week (3010,0086) specifies the day(s) of the week, when the first fraction of the treatment should be delivered. If more than one day is specified, one of the days may be selected to start the treatment.

The treatment then continues as specified in Fraction Pattern (300A,007B), irrespective of when the actual delivery starts.

Examples of Intended Start Day of Week and the relation to Fraction Pattern:

  1. 1 Start Day, one fraction per day

    The treatment should start on Wednesday and be continued at Friday of the first week, followed by treatments at Monday, Wednesday, Friday the next week etc., until all fractions are delivered.

    Number of Fraction Pattern Digits Per Day (300A,0079) = 1

    Repeat Fraction Cycle Length (300A,007A) = 1

    Fraction Pattern (300A,007B) = 1010100

    Intended Start Day of Week (3010,0086) = 0010000

  2. Start of any of 3 days, two fractions per day

    Treatment should start

    • on Monday morning and continued by 1 fraction on Monday afternoon, 2 fractions on Wednesday and Friday

    • or on Monday afternoon and continued by 2 fractions on Wednesday and Friday

    • or on Wednesday morning, followed by a fraction on Wednesday afternoon, followed by 2 fractions on Friday.

    The treatment will continue the next week with 2 fractions on Monday, Wednesday, Friday etc. until all fractions are delivered.

    Number of Fraction Pattern Digits Per Day (300A,0079) = 1

    Repeat Fraction Cycle Length (300A,007A) = 2

    Fraction Pattern (300A,007B) = 11001100110000

    Intended Start Day of Week (3010,0086) = 11001000000000
