X-ray, Electron, and Ion Beam
Emphasis is on: simulation, design and development of new detector systems; new readout methods that enhance the signal quality for x-ray image generation; designs of novel imaging geometries; algorithms that compensate for the physical properties of the detection system to improve the clinical reliability of the image (reconstruction algorithms); and approaches to radiation dose reduction, especially in CT. Of interest are diagnostic image enhancements via photon counting, dual energy, and new applications of cone-beam tomography.
The emphasized topics are meant to lead toward: improved clinical (CT, mammography) cameras or new camera geometries; new signal-processing and image-generation algorithms; corrections for image artifacts for enhanced reliability of clinical images; studies of x-ray physics to estimate absorbed energy of diagnostic scans; and methods of visualizing or measuring therapy doses. Investigating the associated dosimetry estimations help to decrease the risk of diagnostic and therapy techniques.

CT images are more detailed than conventional x-ray images. Image slices that CT scans produce can be 2 or 3 dimensional and can reveal abnormal structures or help the physician plan and monitor treatments.
X-rays were one of the first forms of biomedical imaging and NIBIB's 60 Seconds of Science explains how they create those images of bones we all know well.
