X-ray imaging tricks increase resolution and cut dose


The image compares a conventional CT scan (l) and a scan with the new approach and 1/25th the dose

An international research team has proposed a way to make high-resolution, 3D images of breast tissue while reducing the delivered X-ray dose.

Breast tissue is particularly susceptible to X-ray radiation so 3D scanning is generally not employed.

Now a team reporting in Proceedings of the National Academy of Sciences suggests a different form of X-rays and a new image analysis approach.

However, new compact X-ray sources are needed to bring the idea to the clinic.
