Digital breast tomosynthesis: computer-aided detection of clustered microcalcifications on planar projection images

Abstract: This paper describes a new approach to detection of microcalcification clusters (MCs) in digital breast tomosynthesis (DBT) via its planar projection (PPJ) image. With IRB approval, two-view (cranio-caudal and mediolateral oblique views) DBTs of human subject breasts were obtained with a GE GEN2 prototype DBT system that acquires 21 projection angles spanning 600 in 30 increments. A data set of 307 volumes (154 human subjects) was divided by case into independent training (127 with MCs) and test sets (104 with… Show more

“…Convolutional neural networks (CNNs) have been used previously to classify patterns in medical images for use with computer-aided detection and specifically for microcalcification detection in mammograms. [19][20][21][22][23][24][25][26] In these applications, the training sets were typically small, generally using less than 500 samples. As computational power grows, CNNs with very complex architectures that require training with massive data become practical.…”

“…The CAD systems for the 60°-21PV geometry based on the DBT reconstructed volume and the PPJ image were developed and described in detail previously (Samala et al , 2014b; Samala et al , 2014c). These CAD systems were applied to the 60°-21PV data set and the 30°-11PV data set.…”

“…In our laboratory, a GE GEN2 prototype DBT system acquiring 21 PVs over a 60° tomographic angle was used for collecting DBT cases. We have been developing methods to detect MCs in DBT (Sahiner et al , 2012; Samala et al , 2014c), PVs (Wei et al , 2014), and PPJ image (Samala et al , 2014b). Our CAD systems achieved 85% sensitivity at 2.16 FPs/view in DBT volume, 90% sensitivity at 1.55 FPs/view in PVs, and 85% sensitivity at 0.71 FPs/view in PPJ images.…”

“…A critical component of such a system is accurate segmentation of the bladders from the surrounding structures, which is a challenging problem because of the presence of the non-contrast and contrast-filled regions in the bladder and the low contrast boundaries between the bladder and the adjacent structures in the abdomen. Convolutional neural networks (CNN) have been used previously to classify patterns in medical images for use with computer-aided detection and specifically for microcalcification detection in mammograms [2][3][4][5][6][7][8][9][10] . In this study, we investigated the application of a deep-learning convolutional neural network (DL-CNN) by to bladder segmentation.…”
