Segmentation of skin lesions is considered as an important step in computer aided diagnosis (CAD) for melanoma diagnosis. There have many attempts to segment skin lesions in a semi- or fully-automated manner. Existing methods, however, have problems with over- or under-segmentation and do not perform well with challenging skin lesions such as when a lesion is partially connected to the background...
Adrenal lesions include a wide variety of benign and malignant neoplasms of the adrenal gland, and are seen in up to 5% of computed tomography (CT) examinations of the abdomen. Better identification of these lesions is important for effective management and patient prognosis. Detection on low-contrast CT images, however, even for experienced physicians can be difficult and error-prone, because the...
The availability of medical imaging data from clinical archives, research literature, and clinical manuals, coupled with recent advances in computer vision offer the opportunity for image-based diagnosis, teaching, and biomedical research. However, the content and semantics of an image can vary depending on its modality and as such the identification of image modality is an important preliminary step...
Multi-modality positron emission tomography and computed tomography (PET-CT) imaging depicts biological and physiological functions (from PET) within a higher resolution anatomical reference frame (from CT). The need to efficiently assimilate the information from these co-aligned volumes simultaneously has resulted in 3D visualisation methods that depict e.g., slice of interest (SOI) from PET combined...
Medical imaging is a fundamental component of modern healthcare where majority of medical conditions can benefit from some kinds of imaging. A dual-modal positron emission tomography - computed tomography (PET-CT) has increasingly become the preferred imaging method to stage the common cancers and to assess treatment response. For example, PET image can quantitatively assess the treatment before morphological...
There exist many viewers for single-modal medical images that are efficient and are equipped with powerful analysis tools. However, there is a distinct lack of efficient image viewers for multi-modality images, particularly for displaying multiple follow-up studies that depict a patient's response to treatment over time. Such viewers would be required to display large amounts of image data. In this...
Modern medical practice gives rise to a significant volume of electronic data, and numerous online personal health record (PHR) banking services have emerged to satisfy the growing demand for self-management of this data. These services provide interoperable, centralized repositories that collect this data and make it ubiquitously accessible to patients, providers and referring practitioners by means...
