To this end, we train different image-to-image translation models to synthesize magnetic resonance images of brain volumes with and without stroke lesions from semantic segmentation maps. In addition, we train a generative adversarial network to generate synthetic lesion masks. Subsequently, we combine...
. The spatial orientation is measured in the same way as in a borehole geometry sonde. The optical imager requires a transparent drilling fluid like fresh water or air. Optical imagers should not be confused with borehole cameras, which deliver real-time high quality videos with a normal wide...
Privacy concerns around sharing personally identifiable information are a major barrier to data sharing in medical research. In many cases, researchers have no interest in a particular individual’s information but rather aim to derive insights at the le
Background Medical imaging became a standard in diagnosis and medical intervention for the visual representation of the functionality of organs and tissues. Through the increased availability and usage of modern medical imaging like Magnetic Resonance Imaging (MRI) or Computed Tomography (CT), the need...
Background Magnetic resonance imaging (MRI) is corrupted by Rician noise, which is image dependent and computed from both real and imaginary images. Rician noise makes image-based quantitative measurement difficult. The non-local means (NLM) filter has been proven to be effective against additive ...
Medical image segmentation aims to delineate organs or lesions in images from computed tomography (CT), magnetic resonance imaging (MRI), optical imaging, and other medical imaging modalities, and serves as a basis for subsequent quantitative image analysis in a wide range of clinical and research ...
Estimation of ground surface topography and velocity model by SAR-GPR and its application to landmine detection The velocity is used in normal moveout correction (NMO) to adjust the time delay of multi-offset data, and also applied to migration for reconstruction... X Feng,RS Harmon,JT Broach...

The mean change and 95% CI were back-transformed for presentation in terms of the percentage change from baseline, along with the corresponding P-value. Assumptions of normality were explored graphically through normal probability plots for the residuals from fitting this model. If assessment of the...
The image samples were provided by the Department of Otorhinolaryngology-Head and Neck Surgery at Tri-Service General Hospital (Taipei, Taiwan). The subjects were divided into two groups; the non-LPR group composed of 246 subjects including normal patients and those with polyps, cysts and leukamus...
