Digital Breast Tomosynthesis (DBT) is an efficient method to diagnose changes in the breast tissues. However, it may promote some future detriment to the patient exposed in this test. The future effects can be evaluating using absorbed dose values. A mammographic phantom should be chosen to simulate approximately the properties of a compressed breast in terms of the primary and dispersed radiation spectrum that exits its lower surface. The use of PMMA has important advantages. It is cheaper than substitutes for specially manufactured fabrics and is more available. The objective of this work will be to estimate the dose profile that a real breast would receive during a DTB examination. For this purpose a breast phantom with acrylic materials (PMMA) and dimensions similar to those of a real breast will be constructed, and the dose will be measured on the surface (ESAK profile) and in the middle cut (air kerma profile) of the breast phantom using the radiochromic film.

Digital breast tomosynthesis is an advancement of mammography, and has the potential to overcome limitations of standard digital mammography. This study aimed to compare first-generation digital breas...
The purpose of this study was to test the hypothesis whether two-view wide-angle digital breast tomosynthesis (DBT) can replace full-field digital mammography (FFDM) for breast cancer detection.
The introduction of digital breast tomosynthesis (DBT) into the French breast cancer screening program is forecast by the authorities. The aim of the present study was to evaluate image quality phanto...
To evaluate the impact of double reading automated breast ultrasound (ABUS) when added to full field digital mammography (FFDM) or digital breast tomosynthesis (DBT) for breast cancer screening.
This study was undertaken to compare the two image-quality phantoms commonly used in full-field digital mammography (FFDM) and digital breast tomosynthesis (DBT) imaging.
This randomized phase III trial studies digital tomosynthesis mammography and digital mammography in screening patients for breast cancer. Screening for breast cancer with tomosynthesis ma...
The aim of the study is to compare early performance measures and economic aspects of organized breast cancer screening for women screened using digital breast tomosynthesis+synthetic mamm...
In March 2009, Health Canada approved Tomosynthesis for use in screening and diagnosis of breast cancer. The Tomosynthesis technology is designed as a complementary imaging model that is i...
This randomized phase II trial studies how well abbreviated breast magnetic resonance imaging (MRI) and digital tomosynthesis mammography work in detecting cancer in women with dense breas...
Mammography remains the current standard in the detection of breast cancer. However, conventional two-view mammography will not detect all cancers. The major limiting factor of conventio...
The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.
A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from x-ray film or any other detector.

A fluid-filled closed cavity or sac that is lined by an EPITHELIUM and found in the BREAST. It may appear as a single large cyst in one breast, multifocal, or bilateral in FIBROCYSTIC BREAST DISEASE.
Self evaluation of whole blood glucose levels outside the clinical laboratory. A digital or battery-operated reflectance meter may be used. It has wide application in controlling unstable insulin-dependent diabetes.
A treatment schedule in which the total dose of radiation is divided into large doses.
