Improvements in Fast Mass Microscopy for Large-Area Samples.

Mass spectrometry imaging (MSI) is a technique that analyzes the chemical information and spatial distribution of surface analytes. Most MSI studies are conducted in microprobe mode, in which a mass spectrum is collected for each pixel to create a mass image. Thus, the spatial resolution, sample imaging area, and imaging speed are linked.

Topology optimization of a mandibular reconstruction plate and biomechanical validation.

Objectives: Reconstruction plates, used to bridge segmental defects of the mandible after tumor resection or traumatic bone tissue loss, are subjected to repeated stresses of mastication. High stress concentrations in these plates can result in hardware failure. Topology optimization (TO) could reduce the peak stress by computing the most optimal material distribution in a patient-specific implant (PSI) used for mandibular reconstruction.

A treatment algorithm for patients with large skull bone defects and first results.

Large skull bone defects resulting from craniotomies due to cerebral insults, trauma or tumours create functional and aesthetic disturbances to the patient. The reconstruction of large osseous defects is still challenging. A treatment algorithm is presented based on the close interaction of radiologists, computer engineers and cranio-maxillofacial surgeons.

A classification of cranial implants based on the degree of difficulty in computer design and manufacture.

Background: Skull defects usually create aesthetic and functional disturbances to the patient. These defects are currently reconstructed by using computer-aided design and manufacturing processes. Classification of skull defects becomes important in discussing the complexity of reconstruction in clinical practice or comparing clinical results in scientific articles.
