How can the radiation dose from the combo-mode be reduced to make it comparable with a 2D exam?

The synthetic view plays a pivotal role in reducing radiation dose during mammography when utilizing combination modes, such as 2D and 3D imaging. In mammography, the traditional 2D images are created by capturing multiple exposures, which contributes to the overall radiation dose received by the patient. However, when utilizing 3D imaging techniques, such as digital breast tomosynthesis, the synthetic view can be generated by computationally reconstructing a 2D image from the 3D data set.

This approach is advantageous because it allows for the production of high-quality 2D images without the need for an additional exposure that would normally be required to obtain standard 2D views. By relying on the synthetic view, the operator effectively minimizes the radiation burden to the patient while maintaining the diagnostic efficacy of the examination.

Other methods, like compressing the imaging setting or changing the patient position, might influence image quality or comfort but do not inherently reduce dose in the same systematic manner as the synthetic view does. Additionally, reducing exposure time would likely compromise image quality, as sufficient time is needed to ensure adequate collection of data. Therefore, the use of the synthetic view directly contributes to a comparable radiation dose while preserving the detailed information necessary for effective screening
