Methods and systems providing guidance for operation of a biopsy needle based on ultrasonic imaging. Ultrasonic waves are emitted and detected by a ultrasonic transducer to generate image data. A biopsy needle is identified within the generated image data, and the biopsy needle may be in a pre-fire configuration. Based on the identification of the biopsy needle, the methods and systems may determine a predicted location of the biopsy needle based at least in part on biopsy needle properties. The predicted location of the biopsy needle may be the predicated location of the biopsy needle in its post-fire configuration. At least one indicator may be displayed indicating the determined predicted location.

Biopsy needle visualization

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.

System and method for continuous calibration of X-ray scans

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.

Multiple modality body composition analysis

A real-time fluoroscopic imaging system includes a collimator and a detector which are rotationally movable independent of the support assembly, e.g., c-arm, to which they are mounted. Rotational movement of the collimator and the detector are coordinated such that the orientation of the detector with respect to the collimator does not change. The collimator may include a geared flange member to facilitate rotation, and may be a single molded piece formed of a plastic such as tungsten polymer material. The system may also include a plurality of interchangeable collimators characterized by different shapes. A display is provided to present an image to an operator, and image orientation logic displays a target anatomy in a selected orientation regardless of orientation of the target anatomy relative to the detector, and regardless of rotation of the detector.

Independently rotatable detector plate for medical imaging device

A medical imaging device includes an x-ray source disposed at a first end of an arm, and an x-ray detector disposed at a second end of the arm opposite of the x-ray source. At least one of the x-ray source, the x-ray detector, and a portion of the arm are selectively adjustable with respect to the arm.

Medical imaging device and method of operating a medical imaging device

A helical antenna, which is matched to the desired microwave frequency of 915 MHz, comprises a helix having a linear length which is in the range of 74 to 112 mm or a non-zero integer multiple thereof, and which delivers microwave energy in an optimal heating pattern with little reflected power.
