Ultra-Fast Image Reconstruction of Tomosynthesis Mammography Using GPU

Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...

Deblocking Joint Photographic Experts Group Compressed Images via Self-learning Sparse Representation

JPEG is one of the most widely used image compression method, but it causes annoying blocking artifacts at low bit-rates. Sparse representation is an efficient technique which can solve many inverse problems in image processing applications such as denoising and deblocking. In this paper, a post-processing method is proposed for reducing JPEG blocking effects via sparse representation. In this ...

Breast dose in conventional and digital mamography

Introduction: The amount of doses received in mammography is one of the biggest concerns in the world. According to some statistics, every 12 minutes a woman dies due to breast cancer. Mammography concerned to detect breast cancer at an early stage of the disease as well as for screening, however due to the risk of exposure, the increasingly and widespread use of mammography fo...

Master of Science Thesis Potential for lower doses in digital mammography Tumor detection in hybrid images using a dose reduction simulation method

Pontus Timberg Potential for lower doses in digital mammography Tumor detection in hybrid images using a dose reduction simulation method Purpose: To determine how image quality linked to tumor detection is affected by reducing the absorbed dose to 50% and 30% of standard dose levels, i.e. an average glandular dose of 1.26 mGy for a standard breast according to European guidelines. Material and...
