    • Region growing segmentation of ultrasound images using gradients and local statistics 

      Mercado-Aguirre I.M.; Patiño Vanegas, Alberto; Contreras Ortiz, Sonia Helena (SPIE, 2017)
      This paper describes a region growing segmentation algorithm for medical ultrasound images. The algorithm starts with anisotropic diffusion filtering to reduce speckle noise without blurring the edges. Then, region growing ...

    • Selection of a Stopping Criterion for Anisotropic Diffusion Filtering in Ultrasound Images 

      Guillen J.E.I.; Contreras Ortiz, Sonia Helena (Institute of Electrical and Electronics Engineers Inc., 2019)
      Ultrasound imaging is a safe and cost-effective diagnostic tool, but the quality of the images is affected by speckle noise and artifacts. Anisotropic diffusion filters can be used to reduce noise and preserve the edges ...

    • Texture Analysis of Ultrasound Images for Pneumonia Detection in Pediatric Patients 

      Contreras Ojeda, Sara; Sierra-Pardo C.; Domínguez Jiménez, Juan Antonio; López-Bueno J.; Contreras Ortiz, Sonia Helena (Institute of Electrical and Electronics Engineers Inc., 2019)
      Pneumonia is a condition that can be life-threatening and affects a high number of children around the world. Lung ultrasound can be used for the diagnosis of pneumonia, but requires high experience. This paper presents ...

    • Ultrasound image enhancement: A review 

      Contreras Ortiz, Sonia Helena; Chiu T.; Fox M.D. (2012)
      Medical ultrasound imaging uses pulsed acoustic waves that are transmitted and received by a hand-held transducer. This is a mature technology that it is widely used around the world. Among its advantages are that it is ...
