Med Phys
. 2002 Jan;
28(12):2403-9.
PMID: 11797942
We propose to investigate the use of subregion Hotelling observers (SRHOs) in conjunction with perceptrons for the computerized classification of suspicious regions in chest radiographs for being nodules requiring follow...

Med Phys
. 2002 Jan;
28(12):2394-402.
PMID: 11797941
The purpose of this study was to investigate an information theoretic approach to feature selection for computer-aided diagnosis (CAD). The approach is based on the mutual information (MI) concept. MI...

. 2001 Jun;
28(5):804-11.
PMID: 11393476
A constraint satisfaction neural network (CSNN) approach is proposed for breast cancer diagnosis using mammographic and patient history findings. Initially, the diagnostic decision to biopsy was formulated as a constraint...

Radiology
. 2001 Mar;
218(3):683-8.
PMID: 11230640
Purpose: To evaluate the imaging characteristics of an amorphous silicon flat-panel detector (FPD) for digital chest radiography. Materials And Methods: The 41 x 41-cm digital FPD is constructed on a...

. 2000 Nov;
31(1):15-25.
PMID: 11058691
A computer-assisted diagnostic (CAD) tool was developed for the diagnosis of acute pulmonary embolism (PE) in perfusion lung scans. Forty-five scans (with angiographic proof) were included in the study. The...

AJR Am J Roentgenol
. 2000 Oct;
175(5):1347-52.
PMID: 11044039
Objective: We present case-based reasoning computer software developed from mammographic findings to provide support for the clinical decision to perform biopsy of the breast. Subjects And Methods: The case-based reasoning...

Med Phys
. 2000 Aug;
27(7):1503-8.
PMID: 10947253
Purpose: The effect of image processing, specifically Bayesian image estimation (BIE), on digital mammographic images is studied. BIE is an iterative, nonlinear statistical estimation technique that has previously been used...

Med Phys
. 2000 Jun;
27(5):894-7.
PMID: 10841391
Previously, we have used an anthropomorphic chest phantom to study scatter reduction in digital chest radiography. Image metrics, such as scatter fractions, contrast, noise, and resolution, are not easily measured...

Med Phys
. 2000 Feb;
27(1):13-22.
PMID: 10659733
We have developed a multistage computer-aided diagnosis (CAD) scheme for the automated segmentation of suspicious microcalcification clusters in digital mammograms. The scheme consisted of three main processing steps. First, the...

Med Phys
. 1999 Sep;
26(8):1670-7.
PMID: 10501066
Previously, the authors presented an algorithm that identifies lung regions in a digitized posteroanterior chest radiograph (DCR) by labeling each pixel as either lung or nonlung. In this manuscript, the...
