Systems and methods for improving radiographic scanning. In an example, the technology relates to a system for performing radiographic scanning. The system includes a photon source configured to emit photons. The system also includes a photon counting detector for detecting photons emitted from the photon source after passing through a target. The photon counting detector comprising first pixels having a first size and second pixels having a second size, and the first size is greater than the second size.

A dual-energy X-ray absorptiometry ('DXA') system includes an x-ray source assembly comprising a source carriage to move the x-ray source assembly along a scan path, the scan path comprising an active scan portion and a reference measurement portion. A detector assembly including a detector carriage to move the detector assembly with the source assembly and to collect scan data at active scan portions. A support structure supporting the source and detector assemblies. A calibration controller coupled a calibration element having a known x-ray attenuation value and configured position the calibration element between the source and detector assemblies during the reference measurement portion and to remove the calibration element from between the source and detector assemblies during the active scan portion. A processing unit operable to compare the reference measurement against an expected reference value to identify a variance and to selectively trigger an action in response to the variance.

Systems and methods for determining body composition by combining dual-energy x-ray (DXA) technology with three-dimensional (3D) optical technology and/or bioimpedance technology. A multi-modality scanning system may include a dual-energy x-ray source and an x-ray detector mounted to opposing sides a c-arm and configured to scan a patient on a optically translucent table. The system may also include one or more 3D optical imaging devices to capture 3D optical images of the patient substantially concurrently with the emission of the dual energy x-rays. A bioimpedance machine may also be included in the multi-modality scanning system. Data based on the dual-energy x-rays may be combined with the data from the 3D optical images and/or the bioimpedance data to generate values of at least three compartments selected from: bone, fat tissue, lean tissue, dehydrated lean tissue, and water.

A system for measuring muscle mass of a patient has a dual-energy radiation emission source. A radiation detector is configured to detect radiation emitted from the dual-energy radiation emission source passed through the patient. A processor has a memory with storing instructions, that when executed by the processor, perform a set of operations. The operations include receiving radiation detection data; generating a scan representation; identifying a primary fat target; determining an amount of fat in the primary fat target; comparing the amount of fat in the primary fat target to a reference; and based on the comparison, correcting an estimated amount of lean tissue to generate a corrected muscle mass value.

Methods for physiological state determination in body scans

A method of generating a visual representation of a complex medical diagnosis includes receiving a first signal corresponding to a measurement of a patient biological condition. A second signal corresponding to a measurement of a patient performance condition is also received. The first and second signals are processed and a visual representation of a diagnostic assessment is generated. The diagnostic assessment is based at least in part on the patient biological condition and the patient performance condition. The visual representation is marked with the measurement of the patient biological condition and the measurement of the patient performance condition.

Dual-energy absorptiometry is used to estimate intramuscular adipose tissue metrics and display results, preferably as related to normative data. The process involves deriving x-ray measurements for respective pixel positions related to a two-dimensional projection image of a body slice containing intramuscular adipose tissue as well as subcutaneous adipose tissue, at least some of the measurements being dual-energy x-ray measurements, processing the measurements to derive estimates of metrics related to the intramuscular adipose tissue in the slice, and using the resulting estimates. Processing the measurements includes an algorithm which places boundaries of regions, e.g., a large region and a smaller region. The regions are combined in an equation that is highly correlated with intramuscular adipose tissue measured by quantitative computed tomography in order to estimate intramuscular adipose tissue.

Measuring intramuscular fat

A cover board for use in a roofing system includes a core formed from recycled material. The core has a first major surface and a second major surface and the recycled material includes a plastic material. At least one region of the core has a concentration of plastic greater than a concentration of plastic within a remainder of the core.
