Number of weeks needed to describe fraction pattern.
Required if Weekday Fraction Pattern Sequence (3010,0087) is present.
See Section C.36.2.1.1.1.1.
The Radiation Fraction Pattern describes the intended scheme, i.e., how fractions are to be distributed along calendar days for the actual radiation set.
Examples of Fraction Patterns:
1 fraction per day (Monday to Friday) , no fractions on Saturday and Sunday, 1 week-pattern:
Number of Fraction Pattern Digits Per Day (300A,0079) = 1
Repeat Fraction Cycle Length (300A,007A) = 1
Fraction Pattern (300A,007B) = 1111100
2 fractions per day (Monday to Friday) , no fractions on Saturday and Sunday 1 week-pattern:
Number of Fraction Pattern Digits Per Day (300A,0079) = 2
Repeat Fraction Cycle Length (300A,007A) = 1
Fraction Pattern (300A,007B) = 11111111110000
1 fraction per day (Monday, Wednesday, Friday) , no fractions on Saturday and Sunday 1 week-pattern:
Number of Fraction Pattern Digits Per Day (300A,0079) = 1
Repeat Fraction Cycle Length (300A,007A) = 1
Fraction Pattern (300A,007B) = 1010100
2 fractions per day (Monday, Wednesday, Friday) , one fraction on Saturday morning and Sunday afternoon 1 week-pattern:
Number of Fraction Pattern Digits Per Day (300A,0079) = 2
Repeat Fraction Cycle Length (300A,007A) = 1
Fraction Pattern (300A,007B) = 11001100111001
1 fraction per day every other day 2 week-pattern:
Number of Fraction Pattern Digits Per Day (300A,0079) = 1
Repeat Fraction Cycle Length (300A,007A) = 2
Fraction Pattern (300A,007B) = 10101010101010
