Diffuse optical mammography is a non-invasive emerging technique that investigates the breast composition through spectral analysis. It is an example of diffuse optical imaging, still within the research environment. It showed promising results for breast cancer risk assessment, lesion characterization, therapy monitoring and prediction of ...
Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
CT data sets have a very high dynamic range which must be reduced for display or printing. This is typically done via a process of "windowing", which maps a range (the "window") of pixel values to a grayscale ramp. For example, CT images of the brain are commonly viewed with a window extending from 0 HU to 80 HU.
Radiation treatment to the chest area between ages 10 and 30 ... For example, if a woman at high risk has a close relative who was diagnosed with breast cancer, “a general rule is to start ...
Two forms of radiographic images are in use in medical imaging. Projection radiography and fluoroscopy, with the latter being useful for catheter guidance. These 2D techniques are still in wide use despite the advance of 3D tomography due to the low cost, high resolution, and depending on the application, lower radiation dosages with 2D technique.
Tomosynthesis, also digital tomosynthesis (DTS), is a method for performing high-resolution limited-angle tomography at radiation dose levels comparable with projectional radiography. It has been studied for a variety of clinical applications, including vascular imaging, dental imaging, orthopedic imaging, mammographic imaging, musculoskeletal ...
Starting Tuesday, Sept. 10, 2024, all mammogram facilities across the country will be required to notify patients about the density of their breasts as part of updated mammography regulations ...
Digital mammography is a specialized form of mammography that uses digital receptors and computers instead of X-ray film to help examine breast tissue for breast cancer. [9] The electrical signals can be read on computer screens, permitting more manipulation of images to allow radiologists to view the results more clearly.
