    Today’s 3D-printed digital sculpture can be traced back—not only in a technical sense—to the 1960s, when our digital culture developed. Using the examples of pioneers Robert Mallary and Charles Csuri, this paper reconstructs and distinguishes computer-based productions of sculpture, its reception, and its ontology. One focus is the discourse of sculpture, image, and form. A comparison with Minimal, Serial, and Conceptual Art is suggested not only because Minimal Art was a hot spot of sculptural discourse, but also because it reveals correspondences between digital and non-digital arts, which exist on the level of draft, production, and discourse: a creation with certain machines, mathematization, automatization, mechanization, and a 2D/3D-discourse.It will be argued that the examined digital and non-digital artforms in the 1960s, the time of pre-post-digital art, are only understandable in relation to each other and their common historical con-text: cybernetics, systems theory, the Cold War, and computerization. Taking the cultural-historical and politico-economic context into account, it will be demonstrated that one can identify specific reactions to digital technology and media and its impacts on art and society—which is why I call the non-digital artforms "co-digital art."

    Abstract: Background
    Intraoperative 3-dimensional (3D) navigation is increasingly being used for pedicle screw placement. For this purpose, dedicated mobile 3D C-arms are capable of providing intraoperative fluoroscopy-based 3D image data sets. Modern 3D C-arms have a large field of view, which suggests a higher radiation exposure. In this experimental study we therefore investigate the radiation exposure of a new mobile 3D C-arm with large flat-panel detector to a previously reported device with regular flat-panel detector on an Alderson phantom.

    Methods
    We measured the radiation exposure of the Vision RFD 3D (large 30 × 30 cm detector) while creating 3D image sets as well as standard fluoroscopic images of the cervical and lumbar spine using an Alderson phantom. The dosemeter readings were then compared with the radiation exposure of the previous model Vision FD Vario 3D (smaller 20 × 20 cm detector), which had been examined identically in advance and published elsewhere.

    Results
    The larger 3D C-arm induced lower radiation exposures at all dosemeter sites in cervical 3D scans as well as at the sites of eye lenses and thyroid gland in lumbar 3D scans. At ​​male and especially female gonads in lumbar 3D scans, however, the larger 3D C-arm showed higher radiation exposures compared with the smaller 3D C-arm. In lumbar fluoroscopic images, the dosemeters near/in the radiation field measured a higher radiation exposure using the larger 3D C-arm.

    Conclusions
    The larger 3D C-arm offers the possibility to reduce radiation exposures for specific applications despite its larger flat-panel detector with a larger field of view. However, due to the considerably higher radiation exposure of the larger 3D C-arm during lumbar 3D scans, the smaller 3D C-arm is to be recommended for short-distance instrumentations (mono- and bilevel) from a radiation protection point of view. The larger 3D C-arm with its enlarged 3D image set might be used for long instrumentations of the lumbar spine. From a radiation protection perspective, the use of the respective 3D C-arm should be based on the presented data and the respective application
