Using external actuation sources to navigate untethered drug-eluting microrobots in the bloodstream offers great promise improving selectivity of drug delivery, especially oncology, but current field forces are difficult maintain with enough strength inside human body (>70-centimeter-diameter range) achieve this operation. Here, we present an algorithm predict optimal patient position respect gravity during endovascular microrobot navigation. Magnetic resonance navigation, using magnetic...

Abstract Introduction Insufficient blood supply to the posterior rectal remnant after proctectomy is a possible mechanism for anastomotic leakage. The median sacral artery (MSA) not generally considered participate in supply, although some case studies have reported rectum being supplied by it. aim of this study elucidate anatomy MSA relation wall. Methods Nineteen embalmed cadavers (12 males, seven females; mean age: 76 ± 9 years) were injected with colored radio‐opaque mixture aortic...
Cardiac gating, synchronizing medical scans with cardiac activity, is widely used to make quantitative measurements of physiological events and obtain high-quality free pulsatile artefacts. This can provide important information for disease diagnosis, targeted control microrobots, etc. The current work proposes a low-cost, self-adaptive, MRI-compatible gating system.The system its processing algorithm, based on the monitoring analysis blood pressure waveforms, are proposed. tested in an...
Magnetic steering of superparamagnetic drug-eluting particles (SMDEPs) loaded with anti-tumor drugs across hepatic arteries is a promising technique to perform segmental liver embolization for patients hepatocellular carcinomas (HCCs). These aggregates (20 &plusmn; 6 SMDEPs) are sequentially released specially designed injector through catheter in the proper artery swine placed an MRI. Manual segmentation was previously done localize and count (volume artifact) each lobe. We propose...
