TONY FROC dataset

Description

This is referred to in the book as the "TONY" dataset. It consists of 185 cases, 89 of which are diseased, interpreted in two treatments ("BT" = breast tomosynthesis and "DM" = digital mammography) by five radiologists using the FROC paradigm.

Usage

dataset01

Format

A list with 3 elements: $ratings, $lesions and $descriptions; $ratings contain 3 elements, $NL, $LL and $LL_IL as sub-lists; $lesions contain 3 elements, $perCase, $IDs and $weights as sub-lists; $descriptions contain 7 elements, $fileName, $type, $name, $truthTableStr, $design, $modalityID and $readerID as sub-lists;

• rating$NL, num [1:2, 1:5, 1:185, 1:3], ratings of non-lesion localizations, NLs

• rating$LL, num [1:2, 1:5, 1:89, 1:2], ratings of lesion localizations, LLs

• rating$LL_ILNA, this placeholder is used only for LROC data

• lesions$perCase, int [1:89], number of lesions per diseased case

• lesions$IDs, num [1:89, 1:2], numeric labels of lesions on diseased cases

• lesions$weights, num [1:89, 1:2], weights (or clinical importances) of lesions

• descriptions$fileName, chr, "dataset01", base name of dataset in 'data' folder

• descriptions$type, chr "FROC", the data type

• descriptions$name, chr "TONY", the name of the dataset

• descriptions$truthTableStr, num [1:2, 1:5, 1:185, 1:4] 1 1 1 1 ..., truth table structure

• descriptions$design, chr "FCTRL", study design, factorial dataset

• descriptions$modalityID, chr [1:2] "BT" "DM", treatment labels

• descriptions$readerID, chr [1:5] "1" "2" "3" "4" ..., reader labels
