Assessing multiple-group diagnostic problems with multi-dimensional receiver operating characteristic surfaces: Application to proton MR Spectroscopy (MRS) in HIV-related neurological injury
(2008)We present the multi-dimensional Receiver Operating Characteristic (ROC) surface, a plot of the true classification rates of tests based on levels of biological markers, for multi-group discrimination, as an extension of ... -
An automated blastomere identification method for the evaluation of day 2 embryos during IVF/ICSI treatments
(2018)Purpose Evaluation of human embryos is one of the most important challenges in vitro fertilization (IVF) programs. The morphology and the morphokinetic parameters of the early cleaving embryo are of critical clinical ... -
Classification of dermatological images using advanced clustering techniques
(2010)Computer vision-based diagnosis systems have been widely used in dermatology, aiming at the early detection of skin cancer and more specifically the recognition of malignant melanoma tumor. This paper proposes a novel ... -
Computer-aided clinical image analysis for non-invasive assessment of tumor thickness in cutaneous melanoma
(2021)Objective: Computerized clinical image analysis is shown to improve diagnostic accuracy for cutaneous melanoma but its effectiveness in preoperative assessment of melanoma thickness has not been studied. The aim of this ... -
Computer-based automated estimation of breast vascularity and correlation with breast cancer in DCE-MRI images
(2017)Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) with gadolinium constitutes one of the most promising protocols for boosting up the sensitivity in breast cancer detection. The aim of this study was twofold: ... -
Deep Endoscopic Visual Measurements
(2019)Robotic endoscopic systems offer a minimally invasive approach to the examination of internal body structures, and their application is rapidly extending to cover the increasing needs for accurate therapeutic interventions. ... -
Incidental non-cardiac findings of a coronary angiography with a 128-slice multi-detector CT scanner: Should we only concentrate on the heart?
(2010)Objective: To evaluate the spectrum, prevalence, and significance of incidental non-cardiac findings (INCF) in patients referred for a non-invasive coronary angiography using a 128-slice multi-detector CT (MDCT). Materials ... -
Intelligent visual localization of wireless capsule endoscopes enhanced by color information
(2017)Wireless capsule endoscopy (WCE) is performed with a miniature swallowable endoscope enabling the visualization of the whole gastrointestinal (GI) tract. One of the most challenging problems in WCE is the localization of ... -
Measurement and modeling of microbial growth using timelapse video
(2020)The development of timelapse videos for the investigation of growing microbial colonies has gained increasing interest due to its low cost and complexity implementation. In the present study, a simple experimental setup ... -
Measurement of ultrasonic diaphragmatic motion
(2015)The motion characteristics of the diaphragmatic muscle may provide useful information about normal and abnormal diaphragmatic function and indicate diaphragmatic weakness. The objective of this paper was to introduce a ... -
Novel Cost Function Definition for Minimum-Cost Tractography in MR Diffusion Tensor Imaging
(2020)Magnetic resonance imaging (MRI) is an established clinical technique that measures diffusion-weighted signals, applied primarily in brain studies. Diffusion tensor imaging (DTI) is a technique that uses the diffusion-weighted ... -
Prospective PET image quality gain calculation method by optimizing detector parameters
(2015)Background Lutetium-based scintillators with highperformance electronics introduced time-of-flight (TOF) reconstruction in the clinical setting. Let G′ be the total signal to noise ratio gain in a reconstructed image using ... -

Technical evaluation of in vivo abdominal fat and IMCL quantification using MRI and MRSI at 3 T
(2008)Objectives: The objectives of this study were to develop protocols that measure abdominal fat and calf muscle lipids with magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS), respectively, at 3 T and ... -
Wavelet-based compression with ROI coding support for mobile access to DICOM images over heterogeneous radio networks
(2009)Most of the commercial medical image viewers do not provide scalability in image compression and/or region of interest (ROI) encoding/decoding. Furthermore, these viewers do not take into consideration the special requirements ...
