A total of 71 participants completed an online survey requiring analysis of published virtual 3D skeletal models. Participants were asked to rate their confidence in the methodology and overall sex/age estimation, as well as preference for assessment method for each skeletal model. Statistical Analysis revealed that level of experience in analysing dry bones was found to not be associated with higher confidence in analysing 3D virtual remains (p=0.360 for sex of skull; p=0.494 for sex of os coxa; p=0.845 for age of os coxa). Confidence ratings for students in analysing skeletal remains in person did not predict perceived difficulty of analysing 3D virtual skeletal models (p=0.717 for sex of skull; p=0.579 for sex of os coxa; p=0.733 for age of os coxa). Prior 3D virtual experience did make a difference in confidence levels in the estimation of skull-sex and os coxa-age models (p=003 and p=0.001). Yet, prior 3D experience did not impact confidence levels with os coxa-sex (p=0.093). To provide insight into the results, the social cognitive concept of the ‘self-efficacy’ theory is discussed.</p></div>","PeriodicalId":40763,"journal":{"name":"Forensic Imaging","volume":"33 ","pages":"Article 200544"},"PeriodicalIF":1.1,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49736544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technical aspect of this is that all currently used visualization methods (volume rendering, cinematic rendering and particle tracing, shaded surfaces and iso-surfaces) are defined by a CT-density threshold, whereas the user at least implicitly expects the bone to have a certain minimum density CT. However, some bone regions, typically those with relatively thin bone, do not meet these expectations, and lowering the threshold for visualization then results in all sorts of non-bone tissue being seen in the rendered images. To provide a more authentic PMCT visualization of bone, we identified a mixed data gradient model that improves the data from CT by increasing the CT density of low-density bone regions (but not of non-bone tissues).
