The High Throughput Virtual Slit (HTVS™) is a novel spectroscopic technology which simultaneously maximizes spectral resolution and throughput. We describe the advantages of HTVS spectrometers for Raman measurements and hyperspectral imaging.

In the span of 6 years 350 patients that were clinically and radiologically diagnosed with avascular necrosis of the femoral head, at different stages, were examined. Patients were examined using comprehensive radiation examination including radiography and multispiral computed tomography (MSCT) of the hip joints, with the aim to diagnosis avascular necrosis of the femoral head at an earlier stage. According to the results of the examination, 121 patients were diagnosed with an earlier stage of avascular necrosis of the femoral head, on 99 patients was performed core decompression via drilling, 22 patients underwent a joint preservation procedure with the removal of the necrosis tissue following with a bone-graft using bonesubstituting bioresorbable material.
