The study will be conducted at a single site with two enrollment groups. Group 1 has a target enrollment of 38 subjects. Group 2 has a target enrollment of 16 subjects. By observing the device's use during standard surgical procedures, we can accurately measure its impact on incision planning accuracy, time efficiency, and overall ease of use compared to traditional neuronavigation systems.

Conventional imaging-based volumetry may have limited accuracy. This study investigates the use of individualized 3D liver models combined to enhance visualization and volumetric analysis of liver anatomy and resection boundaries.\n\nPatients are recruited in the liver outpatient clinic and, upon consent, preoperative 3D models are created using Medics 3D. During surgery, the planned resection is guided by the individualized 3D models. Postoperatively, the resected specimen undergoes CT-based volumetry to compare the predicted resection volume from the 3D model with the actual volume. Routine postoperative follow-up is conducted.
