Tomosynthesis

Tomosynthesis is a method used in radiology to create 3D images through X-ray imaging. It is also known as digital tomosynthesis. This technique is used in various medical fields, including mammography, orthopedics, and pulmonology.

Overview

Tomosynthesis is a type of medical imaging that uses X-rays to capture multiple images of the body from different angles. These images are then combined to create a three-dimensional (3D) image of the area being examined. This allows for a more detailed view of the body's internal structures compared to traditional two-dimensional (2D) X-ray imaging.

Procedure

During a tomosynthesis procedure, the X-ray source moves in an arc around the patient while taking multiple images. These images are then processed by a computer to create a 3D image. The patient is required to stay still during the procedure to ensure clear images are captured.

Applications

Tomosynthesis is used in various medical fields for diagnostic purposes. In mammography, it is used to detect breast cancer by providing a 3D image of the breast tissue. In orthopedics, it is used to examine the bones and joints. In pulmonology, it is used to examine the lungs and other parts of the respiratory system.

Advantages and Disadvantages

One of the main advantages of tomosynthesis is that it provides a more detailed image of the body's internal structures compared to traditional 2D X-ray imaging. This can help in the early detection of diseases such as cancer. However, tomosynthesis exposes the patient to a higher dose of radiation compared to traditional 2D X-ray imaging. This can increase the risk of radiation-induced cancer.
