Das S, Miften M, Zhou S, Bell M, Munley M, Whiddon C, et al.
Med Phys
. 2004 Jul;
31(6):1452-61.
PMID: 15259648
The information provided by functional images may be used to guide radiotherapy planning by identifying regions that require higher radiation dose. In this work we investigate the dosimetric feasibility of...

Baydush A, Catarious Jr D, Lo J, Abbey C, Floyd Jr C
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...

Floyd Jr C, Warp R, Dobbins 3rd J, Chotas H, Baydush A, Vargas-Voracek R, et al.
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...

Baydush A, Floyd Jr C
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...

Baydush A, Ghem W, Floyd Jr C
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...

Drayer J, Vittitoe N, Vargas-Voracek R, Baydush A, Ravin C, Floyd Jr C
Acad Radiol
. 1998 Sep;
5(9):613-9.
PMID: 9750890
Rationale And Objectives: This study was performed to determine physical characteristics of areas on chest radiographs that are suspicious but not definitive for the presence of a pulmonary nodule and...

Baydush A, Bowsher J, Laading J, Floyd Jr C
Med Phys
. 1997 Apr;
24(4):539-45.
PMID: 9127306
Purpose: Previously, we have shown that Spatially Varying Bayesian Image Estimation (SVBIE) can be used to reduce scatter and improve contrast-to-noise ratios (CNR) in digital chest radiographs with no degradation...

Baydush A, Floyd Jr C
Acad Radiol
. 1996 Feb;
3(2):129-36.
PMID: 8796653
Rationale And Objectives: Second-order neighborhoods and a spatially varying prior were incorporated into Bayesian image estimation (BIE) to improve image contrast-to-noise ratios (CNRs) while preserving image resolution. Methods: Second-order neighborhoods...

Baydush A, Floyd Jr C
Med Phys
. 1995 Aug;
22(8):1255-61.
PMID: 7476711
Previously, it has been shown that Bayesian image estimation (BIE) can reduce the effects of scattered radiation and improve contrast-to-noise ratios (CNR) in digital radiographs of anthropomorphic chest phantoms by...

Invest Radiol
. 1994 Oct;
29(10):904-10.
PMID: 7852042
Objectives: The authors introduce a Bayesian algorithm for digital chest radiography that increases the signal-to-noise ratio, and thus detectability, for low-contrast objects. Method: The improved images are formed as a...
