3D surface reconstruction using HMH algorithm

Anthropological Facial Approximation in Three Dimensions (AFA3D): Computer‐Assisted Estimation of the Facial Morphology Using Geometric Morphometrics

“…In addition to classic geometric operations (e.g., landmark positioning, plane, line, segment construction, etc. ), TIVMI allows for the reconstruction of 3D surfaces from DICOM files, applying the half‐maximum height algorithm (HMH, see ) in three dimensions . Each facial surface (soft and hard tissues) was reconstructed with this protocol, ensuring an accurate detection of the interface between different tissues and creating a reproducible rendering of the patient's anatomy (Fig.…”

Three-dimensional imaging of past skeletal TB: From lesion to process

“…Special software programs dedicated to anthropology and paleopathology, such as TIVMI ® [11] that are allowing qualitative and quantitative analyzes of both CT slices and observerindependent reliable 3D reconstructions, are making visible paleopathological lesions that cannot be fully identified and/or described and interpreted by conventional medical imaging methods (plain X-ray and 2D CT slices).…”

“…Digital acquisitions were issued from medical CT scan or industrial microCT scan. The high fidelity quality of the 3D reconstructions is due to a specific software program, TIVMI ® (Treatment and Increased Vision for Medical Imaging), based on HMH (Half Maximum Height) algorithm [10] and extended to 3D [11]. It allows locating on CT slices, accurately and reliably, the precise interface between tissues having different densities.…”

“Gueule cassée” (facial injuries): a 3D paleotraumatology study and facial approximation of a Napoleonic soldier who died in 1812 at Königsberg during the Russian Campaign

“…A computer tomographic scan of the cranium and mandible was performed at the Department of Radiology of Moscow State University by one of us (A. V.) on a Philips Brilliance 64 device, using a 512 × 512 matrix, a slice thickness of 0.47 mm, an exposure time of 780 ms, and an X‐ray tube current of 128 mA. Computed tomography (CT) data were analyzed using TIVMI software, developed by Dutailly, Coqueugniot, Desbarats, Gueorguieva, and Synave (). TIVMI has demonstrated an accuracy comparable to other 3D reconstruction software (Guyomarc'h et al, ) as it uses the half maximum height algorithm (Spoor, Zonneveld, & Macho, ) extended to 3D.…”
