Laser-plasma wakefield acceleration (LWFA) is a promising technology that is attracting the attention of the scientific community. It is a new acceleration concept where electrons can be accelerated to very high energy (~150 MeV) in a very short distance (mm scale). Electrons "surf" plasma waves excited by the passage of a high power laser (~1018 Wcm-2) through plasma. Electrons in the LWFA can undergo transverse oscillation and emit synchrotron-like X-ray radiation, commonly known as betatron radiation, in a narrow cone along the laser propagation axis. The properties of both the electrons and the X-rays produced by the LWFA make them excellent candidates for a wide range of applications. In this thesis, both betatron X-ray and bremsstrahlung sources from the ALPHA-X laboratory are used to carry out both conventional imaging and X-ray phase-contrast imaging experiments to explore the feasibility of real-world applications. The characterisation of the betatron X-ray radiation produced by the LWFA in the ALPHA-X laboratory is presented. In the last Chapter, a brief discussion of the potential of LWFA technology for clinical applications is presented.
