 The liver used from this project was bought in a local butcher shop and belonged to a lamb. The CT scan was performed at the Nuclear Medicine Department in Hospital Clínic, Barcelona (Figure 19) using a SOMATOM definition AS (SIEMENS). Due to the state of the animal's liver, a first trial of the scan failed since the vasculature was indiscernible. Thus, the vasculature had to be filled with a mixture of vaseline and Ultravist 300mg/ml'','' which is an injectable contrast medium (a dye) containing iodine. The mixture was warmed up in order to ensure a semi-liquid texture that would fill the whole vasculature. High resolution CT image data (image size 512 x 512 px, slice thickness 0.6mm) of the animal's liver was saved as Digital Imaging and Communications in Medicine (DICOM) data.

	In this section, the following question will be answered: has AR previously been used in hepatic surgeries? Currently, there are no studies focusing on the application of AR through a HMD in hepatic open surgeries. However, the increasing demand for AR-based systems in minimally-invasive surgeries (MIS) has yielded several studies. Table 1 summarizes the most relevant papers and news from the past seven years.

 It can be seen that the 3D Printing and Writing of the thesis activities are not present in the pie chart as their costs are too small compared to the others. Again, AR application receives the vast majority of the budget, due to the Hololens ™ device and the Dell computer. However, this graph would be slightly different if the Macbook Air computer cost was included in activities C and F: their section in the graph would increase significantly.
 All in all, the total budget of the project does not exceed 10.000€ and therefore, it cannot be categorized as an expensive project. This budget analysis is useful to observe where costs should be reduced if the project continuation.
