“…The Lodox Statscan (Lodox Systems Pty [Ltd] Sandton, South Africa) is a full body, fast acquisition radiographic device that was initially designed in South Africa for the diamond mining industry (Knobel et al, 2006;Evangelopoulos et al, 2009;Douglas et al, 2010). The slot-scanning design offers the ability to generate images with minimal distortion because the Xray source is projected through a collimated fan-beam onto a detector, which moves in synchrony over the patient.…”

Subadult age estimation is considered the most accurate parameter estimated in a subadult biological profile, even though the methods are deficient and the samples from which they are based are inappropriate. The current study addresses the problems that plague subadult age estimation and creates age estimation models from diaphyseal dimensions of modern children.The sample included 1,310 males and females between the ages of birth and 12 years.Eighteen diaphyseal length and breadth measurements were obtained from Lodox Statscan radiographic images generated at two institutions in Cape Town, South Africa between 2007 and 2012. Univariate and multivariate age estimation models were created using multivariate adaptive regression splines (MARS). K-fold cross-validated 95% prediction intervals (PIs) were created for each model and the precision of each model was assessed.

“…Use of the Lodox Statscan radiographic images may eliminate the problems associated with metric data collection because of the claim to generate minimal distortion in the yaxis (scan direction). The machine is designed to offer rapid image acquisition (10-13 seconds), to produce a highly detailed whole-body image, and to emit extremely low radiation dosage to patients and operators, thus making the machine safer to use than conventional radiography equipment (Knobel et al, 2006;Evangelopoulos et al, 2009). The Statscan has an X-ray tube mounted on one end of a C-arm and an image receptor on the other end (Figure 3).…”

Measuring distortion of skeletal elements in Lodox Statscan‐generated images

Due to a scarcity of available skeletal material, anthropologists and other practitioners face difficulties with either the creation or validation of techniques used to estimate a biological profile in subadults. In order to address this problem, radiographic images of living individuals are often used in lieu of dry skeletal elements. However, radiographic images suffer from distortion. Some problems with metric 2 analyses of radiographic images may be addressed with the Lodox Statscan, an X-ray machine that claims to produce minimal distortion along the scan-axis due to a linear slot-scanning design. The purpose of this research was to measure the distortion of skeletal elements in radiographic images generated from a Lodox Statscan. Skeletal elements subject to multiple imaging variables that affect distortion were radiographed, measured, and then compared to the dry bone measurements through multiple approaches. An 85% percent agreement was obtained within a +/-1 mm range and a 97% agreement within a +/-2 mm range. Percent difference results demonstrate that slot-axis measurements incurred more distortion than scan-axis measurements (11.8% and 2.7%, respectively). Inclusion of foam results in 4.5% more error than when foam is not included in the image. Angled scan-axis measurements also incurred more distortion than either non-angled slot-and scan-axis measurements. A Bland-Altman plot reveals an overall agreement between the radiographic and dry bone measurements, with most measurements falling within the upper and lower limits. Similar measurement error is found in Statscan radiographic and dry bone measurements; therefore, the Statscan offers a radiographic venue to collect metric data.

“…Evangelopoulos et al presented their modified trauma protocol—The Bernese Modified ATLS Protocol—placing Lodox, together with ultrasound, as low-dose imaging adjuncts to the primary survey, allowing for a “ better understanding of patients' injury patterns ” [22]. They also comment that this combination of imaging, before beginning the secondary survey, may allow for a reduction in the number of CT scans required.…”

Full-Body X-Ray Imaging to Facilitate Triage: A Potential Aid in High-Volume Emergency Departments

The levels of traumatic injury seen in South African emergency departments (EDs) are epidemic. This is coupled with a severe lack of resources and adequately trained emergency staff. The Lodox Statscan (LS) is an X-ray scanner capable of producing rapid, low-dose, and full-body X-ray images. In this paper, a new trauma protocol—the Johannesburg trauma protocol—that implements LS scanning on entry to the ED as a triage tool is reported. A case study illustrating the use of LS to triage 63 patients in a single Saturday shift at a level 1 Trauma Centre is also presented. Because of the ability to rapidly and safely provide X-ray imaging information to support clinical decision making, the LS could be a useful tool to aid in resource allocation to improve treatment of the high levels of trauma patients that present to South African EDs daily.
