Visualization Techniques for 3D Microscopic Imaging Data
Three-dimensional (3D) microscopic imaging techniques such as confocal microscopy have become a common tool in measuring cellular structures. While computer volume visualization has advanced into a sophisticated level in medical applications, much fewer studies have been made on data acquired by the 3D microscopic imaging techniques. To optimize the visualization of such data, it is important t...
متن کاملPillcam: the Improved Colon Imaging Device Alternative to a Colonoscopy
Approximately 1.6 million Americans suffer from Crohn's Disease, an inflammatory disease that affects the digestive tract. All patients are required to undergo a colonoscopy as part of the initial diagnosis, a test which allows doctors to look at the inner linings of the large intestine through a small camera to check for ulcers, polyps, tumors and other abnormalities. However, this invasive pr...
متن کاملImaging techniques in dermatology
Since the discovery of X-rays, the use of imaging technology has continued to play an important role in medicine. Technological advancements have led to the development of various imaging modalities, most of which have been used to image organs deep within the human body. More recently, attention has focused on the application of imaging technology for evaluation of the skin. A variety of techn...
متن کاملImproved ASL Imaging with 3D GRASE PROPELLER
Introduction: Arterial Spin Labeling (ASL) uses blood water as an endogenous tracer to non-invasively measure cerebral blood flow. In a previous study, Günther et al. (1) has shown a near 3-fold improvement in perfusion signal-to-noise ratio (SNR) with single-shot 3D GRASE compared to conventional 2D EPI. However, a limitation of 3D GRASE is through-plane blurring caused by T2 decay. Reducing t...
متن کاملInteractive electronic biopsy for 3D virtual colonoscopy
We propose an interactive electronic biopsy technique for more accurate colon cancer diagnoses by using advanced volume rendering technologies. The volume rendering technique defines a transfer function to map different ranges of sample values of the original volume data to different colors and opacities, so that the interior structure of the polyps can be clearly recognized by human eyes. Spec...
