The aim of the project is to collect pre-procedural CT scans, intra-procedural post-evacuation scans as well as immediate post-procedural CT scans to evaluate and collect feedback of two Siemens prototypes: 1) perfusion prototype and 2) automatic hemorrhage detection prototype. The assessment of the prototypes, including its features will focus on the feasibility, usefulness as well as the potential clinical value add in minimally invasive ICH treatment.

The aim of the project is to prospectively collect pre-procedural CT scans, intraprocedural scans post-evacuation (7s DynaCT Sine Spin and DynaCT Multiphase) and immediate post-procedural CT scans to evaluate and collect feedback of two Siemens prototypes. The assessment of the prototypes, including its features, will focus on the feasibility, usefulness, and potential clinical value. In addition to the prospective data collection outlined above, already available pre- and post procedural CT data sets as well as pre- and post-evacuation DynaCT Sine Spin data sets will be collected retrospectively (n=5). These data sets were acquired as part of standard of care procedures. The additional data sets will also be included in the evaluation
