Conclusions: A mandibular finite element model with heterogeneous material properties is built. By analyzing the EM value of this model, it is concluded that the actual EM in anterior-posterior direction in mandibular ramus and EM in superior-inferior direction in mandibular body match the empirical EM better than the other directions.”
“Magnetic particle imaging (MPI) is a promising new medical imaging tracer modality with potential applications in human angiography, cancer imaging, in vivo cell tracking, and inflammation imaging. Here we demonstrate both theoretically and experimentally that Rabusertib inhibitor multidimensional MPI is a linear shift-invariant imaging system with an
analytic point spread function. We also introduce a fast image reconstruction method that obtains the intrinsic
MPI image with high signal-to-noise ratio via a simple gridding operation in x-space. We also demonstrate a method to reconstruct large field-of-view (FOV) images using partial FOV scanning, despite the loss of first harmonic image information due to direct feedthrough contamination. We conclude with the first experimental test of multidimensional x-space MPI.”
“Introduction: We report a redesigned magnetically AZD6094 price anchored and guided systems (MAGS) camera with improved optics and a 30 degrees downward viewing angle that facilitates solitary surgeon laparo-endoscopic single site (LESS) nephrectomy.
Methods: The prototype consists of an external 2 by 6 cm cylinder containing magnets positioned such that the intra-abdominal camera is anchored on the peritoneal surface with a default 30 degrees downward angle. It was inserted through a 3 cm LESS-port periumbilical incision in three pigs (mean 47 kg). The camera was coupled with the handheld magnetic device across the anterior abdominal wall and was steered into position to view the kidney.
LESS nephrectomy was then performed.
Results: Since a standard LESS laparoscope was not needed, only the two operative instruments were inserted through the single incision port, significantly decreasing instrument “”clashing”" compared with traditional LESS nephrectomy. Due to the favorable angle of view of the camera and its self-anchoring capability, no assistant was needed to drive the camera. Instead, the Protein Tyrosine Kinase inhibitor surgeon periodically made minor adjustments to optimize the view. The nephrectomy was completed without complication in an average of 35 minutes in these three nonsurvival animals.
Conclusion: The MAGS camera provides good optics and easy maneuverability during LESS porcine nephrectomy. As with other MAGS instruments, by replacing a traditional transabdominal laparoscope that occupies access port space, use of this insertable camera may diminish some of the “”collision challenge”" of LESS surgery. Also, by being self-anchoring, this prototype may minimize the need for an assistant surgeon.
