Calculate Absolute TRAK Values

Calculates the absolute Total Reference Air Kerma (TRAK) values for tandem applicator, vaginal applicator, and needles across all brachytherapy fractions. Converts percentage contributions to absolute values in cGy at 1m and provides fraction-specific and total TRAK metrics.

Usage

emii_add_trak_absolute(df, num_fractions = 7)

Arguments

df

A data frame containing TRAK percentage columns for multiple fractions

num_fractions

Number of fractions to process (default: 7)

Value

A data frame with added columns: - Fraction-specific absolute values for each component - Total sum columns: trak_tandem_applicator_sum, trak_vaginal_applicator_sum, trak_needles_sum, and trak_total_sum

Examples

if (FALSE) { # \dontrun{
emii_data <- load_embrace_ii()
result <- emii_add_trak_absolute(emii_data)
} # }
