Enhancing quality in Diffusion Tensor Imaging with anisotropic anomalous diffus...
Senra Filho,Antonio Carlos da Silva; Salmon,Carlos Ernesto Garrido; Santos,Antonio Carlos dos; Murta Junior,Luiz OtávioAbstract Introduction: Diffusion tensor imaging (DTI) is an important medical imaging modality that has been useful to the study of microstructural changes in neurological diseases. However, the image noise level is a major practical limitation, in which one simple solution could be the average signal from a sequential acquisition. Nevertheless, this approach is time-consuming and is not often applied in the cl...
Volumetric T1 and T2 magnetic resonance brain toolkit for relaxometry mapping s...
Senra Filho,Antonio Carlos da SilvaAbstract Introduction Relaxometry images are an important magnetic resonance imaging (MRI) technique in the clinical routine. Many diagnoses are based on the relaxometry maps to infer abnormal state in the tissue characteristic relaxation constant. In order to study the performance of these image processing approaches, a controlled simulated environment is necessary. However, a simulated relaxometry image tool ...
A computational tool as support in B-mode ultrasound diagnostic quality control
Senra Filho,Antonio Carlos da Silva; Rodrigues,Erbe Pandini; Elias Junior,Jorge; Carneiro,Antonio Adilton OliveiraINTRODUCTION: The quality control (QC) of biomedical equipment is a very important process for the quality assurance of the instruments used in diagnoses and treatments. Ultrasound diagnostic imaging is one of the most widely used techniques for diagnostic imaging in hospitals and medical clinics. However, the time required to complete several B-mode imaging QC tests in ultrasound equipment is very critical for...
