Meets DICOM conformance yes yes yes standards? Structured report? Other type yes; also stand-alone overlay, presentation state yes; also secondary capture image, radiotherapy yes; also radiotherapy structure set, dicom of DICOM report? overlay, grayscale softcopy structure set, digital mammo image for presentation 6000, gsps, secondary capture, hardcopy print with dicom 6000 overlay PACS integration software gets data directly from mammo unit; server handles routings directly from mammo unit and receives images from pacs but typically via (i.e., software gets info through output goes directly to pacs through pacs (as long as images are for-processing) mammo unit PACS or it acquires info directly from mammo unit) How many units will server 4 4 4 manage? Which image required For-processing For-processing For-processing (e.g., processed image, “for-processing” image, other)? Which views analyzed? rcc, lcc, rmlo, lmlo all screening and diagnostic views except for spot all standard views compression and magnifcation How are regions of interest markers placed at centroid of lesions triangles (calcifications), asterisks (masses) rectangles (microcalcification clusters) (ROI) portrayed? and compass points (masses with calcifications) and elipses (densities) Overall sensitivity and 89% with 0.63 false positives per image 88, 91, 93% overall sensitivity at 0, 1 and 2 operating up to 96% sensitivity specificity for most recently points released algorithm? Algorithm sensitivity 96% for microcalcifications with 0.26 Fpi; 87% 48, 35, 24% specificity; 95, 96, 97% calcification n/a and specificity for for masses with 0.37 Fpi sensitivity (operating point-dependent); 83, 88, 90% microcalcification detection? mass sensitivity (operating point-dependent) For mass detection? Algorithm’s definition of at least 3 calcifications (between 0.2 and 0.6 mm) at least 3 calcifications within 3 mm of each another 3 microcalcifications within 4 mm2 calcification cluster within 6 mm of each other Maximum mass size 5 cm no maximum no maximum algorithm will mark Does algorithm mark ROI found markers in each view where lesion detected yes marks in multiple views if present only in one view? Is number of marks limited? 10 per case 3 calcification marks, 2 mass marks, 2 “malc” marks no limit What is limit? (all per image) User control of algorithm 2 operating points 9 operating points 2 operating points sensitivity Presentation options no options anatomic outlines, lesion metrics and variable mark paper printout of cad report (e.g., histograms)? sizes Is company developing CAD yes; n/a (under development) yes; n/a yes; breast/prostate mri, colon/lung ct for other modalities? Which modalities/conditions?
