Objective: To study the methods of three-dimensional reconstruction of digitized virtual hepatic.
Methods: Images of DSCF 2511-2520 were taken from the database of digitized Virtual Chinese Human female No. 1 (VCH-F1). Method of insertion value algorithm of three-dimensional reconstruction was used to make three-dimensional block diagram. In ordering to auto-judge the position of hepatic solid and hepatic ducts, these images were shown with different colors according to the character of color and location of every spot.
Results: Stereo image of hepatic solid could be shown satisfactorily. Every shape of stereo image and the structure of hepatic duct could be shown by revolving the three-dimensional image with different direction.
Conclusions: The image of hepatic database of digitized Virtual Chinese female No. 1 was exact. The three-dimensional image of the liver and hepatic duct made by insertion value algorithm of three-dimensional reconstruction were distinct, and it was a ideal method of three-dimensional reconstruction.

Objective: The primary research aim was to determine if the use of traditional or 3D printed prosthesis resulted in better functional outcome scores in hip arthroplasty.
Methods: A systematic review and meta-analysis was conducted utilizing the PRISMA 2020 guidelines. Six databases (PubMed, Embase, Scopus, WebOfScience, and Cochrane Library, Google Scholar) were searched yielding 1117 article titles and abstracts.

: Accurate reconstruction of internal temperature fields from surface temperature data is critical for applications such as non-invasive thermal imaging, particularly in scenarios involving small temperature gradients, like those in the human body. : In this study, we employed 3D convolutional neural networks (CNNs) to predict internal temperature fields. The network's performance was evaluated under both ideal and non-ideal conditions, incorporating noise and background temperature variations.

Cauda equina nerve roots may become damaged during neuraxial anesthesia, and post-puncture headache may appear in the case of cerebrospinal fluid leakage if needle tips are deformed due to bone contact when several attempts are needed. Our aim was to verify the correlation between skin-transverse process distance (st) and skin-dural sac distance (d) for calculation of optimal angles in a free visual guide and as a reference for the maximal depth to be traversed by the needle. Randomly selected ex vivo samples ( = 10) were flexed to reproduce the position of the lumbosacral spine during spinal anesthesia.

Background/objectives: The aim of this study was to evaluate changes in trunk height and variations in spino-pelvic parameters during trunk self-elongation. Two populations were studied: non-athletes and gymnasts, who differ in their engagement with core-strengthening exercises.
Methods: EOS biplanar radiographs were taken on 14 non-athletes and 24 gymnasts in both neutral and trunk self-elongation positions.

Nothronychus graffami was a large therizinosaur represented by a single well-preserved individual from the Turonian Tropic Shale of southern Utah. It is characterized by an enlarged abdomen, small tail, and an extensively pneumatized axial skeleton, and is frequently regarded as herbivorous. Given the overall tail reduction and the development of a wide fused synsacrum with widely spaced acetabulae, it is reconstructed with an anteriorly rotated femur and a displaced resting ground reaction force anterior to the center of mass.
