PhantomMSK Trauma

PhantomMSK Trauma is an image-processing software intended to enhance the accuracy of orthopedic trauma component placement by providing intraoperative fluoroscopic image analysis tools, including templating, measurement, and distortion correction. The system utilizes a radiopaque calibration array with C-arm imaging to calculate and correct fluoroscopic distortions, thereby aiding surgeons in assessing implant and anatomical alignment during procedures.

PhantomMSK Trauma is an image-processing software system designed to aid surgeons in the precise positioning of orthopedic trauma components during operations. It functions by analyzing fluoroscopic images acquired from a C-arm, offering tools for templating, measurement, and correcting image distortion. The system is software-based and operates on standard 'commercial off-the-shelf' computer hardware, interfacing with fluoroscopic images displayed outside the sterile field for the surgeon's discretionary use. It is not intended for primary image interpretation and requires clinical judgment for proper use. The scientific basis of the device includes a method to address fluoroscopic distortion, which can be caused by external electromagnetic interference and the inherent characteristics of mapping a planar image onto a curved input phosphor. PhantomMSK Trauma employs software algorithms in conjunction with a proprietary radiopaque calibration array, which attaches to the C-arm's image intensifier, to calculate and correct these distortions. Verification and validation testing, performed at both code and system levels using specific C-arm models (GE OEC 9900 and 9800) and defined image intensifier sizes, confirmed that its templating, measurement, and distortion correction tools performed as intended and met established acceptability criteria.
