  1. 1. Finding Corresponding Regions In Different Mammography Projections Using Convolutional Neural Networks

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Emil Eriksson; [2022]
    Keywords : Machine Learning; Convolutional Neural Network; U-net; Mammography; Corresponding Regions; MLO and CC; Medical Image Processing;

    Abstract : Mammography screenings are performed regularly on women in order to detect early signs of breast cancer, which is the most common form of cancer. During an exam, X-ray images (called mammograms) are taken from two different angles and reviewed by a radiologist. READ MORE

  3. 2. Development of patient-specific fetal head phantom for experimental evaluation of vacuum assisted delivery

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Maria Pop; [2021]
    Keywords : Vacuum assisted delivery; Vacuum extractor device; Traction force; Vacuum pressure; Fetal head phantom; Ultrasound imaging; Sonomicrometry;

    Abstract : Vacuum assisted delivery (VAD) is a common procedure used in the final stage of labor in the situation of a difficult natural delivery. Since the only biomechanical studies concerning the clinical safe traction force were conducted during 70s using simplified models to mimic the fetal head, concerns remain regarding the side effects of this medical intervention when applying high levels of traction forces.

  4. 3. JPEG-deblocking of Blood Cell Images using Deep Learning

    University essay from Lunds universitet/Matematik LTH

    Author : Justin Ma; Julia Hafsbrandt Fovaeus; [2020]
    Keywords : Image Analysis; Image Reconstruction; Image Restoration; Image Compression; Machine Learning; Deep Learning; JPEG; JPEG-deblocking; CellaVision; Neural Networks; Convolutional Neural Networks; Blood Cells; White Blood Cells; Microscopy; Microscope; Mathematics and Statistics;

    Abstract : This thesis investigates the use of convolutional neural networks as a reconstruction or JPEG- deblocking model for JPEG-compressed blood cell images, needed due to the well known block artifacts caused by JPEG-compression. CellaVision develops automated microscopy for blood analysis that detects and classifies blood cells from images. READ MORE

  5. 4. Lossless Image compression using MATLAB : Comparative Study

    University essay from Blekinge Tekniska Högskola

    Author : Surya Teja Kodukulla; [2020]
    Keywords : Algorithms; Compression Ratio; Efficiency; Image Compression; Lossless; Lossy; Quality;

    Abstract : Context: Image compression is one of the key and important applicationsin commercial, research, defence and medical fields. The largerimage files cannot be processed or stored quickly and efficiently. Hencecompressing images while maintaining the maximum quality possibleis very important for real-world applications.

  6. 5. Compression and Decompression of Color MRI Image by Huffman Coding

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Xin Zou; [2018]
    Keywords : ;

    Abstract : MRI image (Magnetic Resonance Imaging) as a universal body checkup method in modern medicine. It can help doctors to analyze the condition of patients as soon as possible. As the medical images, the MRI images have high quality and a large amount of data, which requires more transmission time and larger storage capacity. READ MORE
