Abstract: A method and system of irradiating a liquid-carrying container for inspection, including rotating the container, its contents or both around a rotation axis and irradiating the container with an electromagnetic radiation beam, wherein the irradiated cross-section of the container, irradiated by the electromagnetic radiation beam, is less than the cross-section of the container; and, a method and system for inspecting a liquid-carrying container for one or more test parameters of the container, the contents of the container, or both, including rotating the container, the contents or both around a rotation axis, irradiating the container with an electromagnetic radiation beam from a first direction along an irradiation center plane substantially parallel to the rotation axis, capturing a representation of a section of the container from a second direction along a detection center plane substantially parallel to the rotation axis, and processing the representation, wherein the irradiated cross-section of the con
