Uncertainty-aware asynchronous scattered motion interpolation using Gaussian process regression.

Comput Med Imaging Graph 2018 Dec 21;72:1-12. Epub 2018 Dec 21.

Department of Mathematics and Computer Science, University of Bremen, Bremen, Germany; Fraunhofer Institute for Medical Image Computing MEVIS, Bremen, Germany; Department of Radiology, Harvard Medical School and Brigham and Women's Hospital, Boston, MA 02115, USA.

We address the problem of interpolating randomly non-uniformly spatiotemporally scattered uncertain motion measurements, which arises in the context of soft tissue motion estimation. Soft tissue motion estimation is of great interest in the field of image-guided soft-tissue intervention and surgery navigation, because it enables the registration of pre-interventional/pre-operative navigation information on deformable soft-tissue organs. To formally define the measurements as spatiotemporally scattered motion signal samples, we propose a novel motion field representation. Read More

Technologies for image-guided surgery for managing lymphatic metastases in prostate cancer.

Nat Rev Urol 2019 Jan 15. Epub 2019 Jan 15.

Martini Klinik, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.

One of the challenges for the surgical management of prostate cancer is the lymphatic spread of metastases. Lymph node metastases vary in size (micrometastases (<2 mm) or macrometastases (>2 mm)), and their interactions with the lymphatic environment differ (whether they are hypoxic or connected to blood flow). Thus, devising a universal imaging system and an image-guided surgical approach that supports the resection of all affected lymph nodes is difficult. Read More

Masaharu Hata

Int J Gynecol Cancer 2019 Jan 10. Epub 2019 Jan 10.

Department of Radiation Oncology, Yokohama City University Graduate School of Medicine, Yokohama 236-0004, Japan

As the average lifespan lengthens worldwide, and the older adult population increases, the number of elderly patients with uterine cervical cancer is increasing. Because intensive and invasive treatments, including surgery, are frequently unacceptable in elderly patients, cancer treatments for these patients must be carefully considered. Elderly patients have undergone radiation therapy as less-invasive curative treatment, and it has been shown to be safe and effective for local control of cervical cancer in this population, even among patients aged ≥80 years treated with curative radiation doses.

Management of Extra-articular Deformity in the Setting of Total Knee Arthroplasty.

J Am Acad Orthop Surg 2019 Jan 7. Epub 2019 Jan 7.

From the Adult Reconstruction and Joint Replacement Service (Dr. Sculco), the Department of Orthopaedic Surgery (Dr. Kahlenberg), and Limb Lengthening and Complex Reconstruction Service (Dr. Fragomen and Dr. Rozbruch), Hospital for Special Surgery, New York, NY.

Extra-articular deformities of the femur and tibia in conjunction with advanced knee osteoarthritis pose unique challenges for the arthroplasty surgeon. Careful preoperative planning is needed to evaluate both the intra- and extra-articular deformities and to determine the best route to total knee arthroplasty. An intra-articular compensatory correction can typically be performed if the extra-articular deformity is distant from the joint or if preoperative templating shows that bony cuts do not interfere with ligamentous attachments.

The use of six degrees of freedom couch is only clinically beneficial in stereotactic radio surgery.

Med Phys 2019 Jan 8. Epub 2019 Jan 8.

The Hong Kong Polytechnic University, Hong Kong.

High-accuracy radiotherapy is desired for precise delivery of radiation treatment to cancer. Modern technologies have been developed to pursue this goal, such as image-guided radiation therapy (IGRT), intensity-modulated radiation therapy (IMRT), stereotactic radiosurgery (SRS), and stereotactic body radiation therapy (SBRT). A recent development to improve patient setup accuracy is the six-degrees-of-freedom (6DOF) couch, which overcomes limitations of the four degrees-of-freedom (4DOF) couch in correcting rotational errors of patient positioning by providing additional adjustments for pitch and roll.

Accuracy of computer-assisted surgery in mandibular reconstruction: A postoperative evaluation guideline.

Oral Oncol 2019 Jan 16;88:1-8. Epub 2018 Nov 16.

Department of Oral and Maxillofacial Surgery/Oral Pathology & 3D Innovation Lab, VU University Medical Centre/Academic Centre for Dentistry Amsterdam (ACTA), De Boelelaan 1117, 1081 HV Amsterdam, the Netherlands. Electronic address:

Comparing accuracy results for mandibular reconstructions using computer-assisted surgery (CAS) is limited due to heterogeneity in image acquisition, extent of mandibular resection, and evaluation methodologies between studies. We propose a practical, feasible and reproducible guideline for standardizing evaluation methods to allow valid comparisons of postoperative results and facilitate meta-analyses in the future. It offers a guide to imaging, data comparison, volume assessment of 3-dimensional models, classification of defects, and it also contains a quantitative accuracy evaluation method. Read More

Image-Guided Navigation and Robotics in Spine Surgery.

Neurosurgery 2019 Jan 7. Epub 2019 Jan 7.

Department of Neurosurgery, Rush University Medical Center, Chicago, Illinois.

Image guidance (IG) and robotics systems are becoming more widespread in their utilization and can be invaluable intraoperative adjuncts during spine surgery. Both are highly reliant upon stereotaxy and either pre- or intraoperative radiographic imaging. While user-operated IG systems have been commercially available longer and subsequently are more widely utilized across centers, robotics systems provide unique theoretical advantages over freehand and IG techniques for placing instrumentation within the spine.
