Automated scoring system for cervical dystonia videos

None

Cervical dystonia, also known as spasmodic torticollis, is a kind of movement disorder that can lead to abnormal involuntary neck muscle contraction and head posture, bringing great pain to patients. In clinical practice, the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) is often used to assess cervical dystonia. However, there are few experienced doctors, and the visual observation assessment scheme is subjective. Therefore, we have developed an automated scoring system for cervical dystonia videos, aiming to achieve the video-based intelligent assessment of cervical dystonia through the TWSTRS. Using only the video taken by the consumer camera, the system can automatically track the patient’s face and body in the video, calculate and analyze the relevant angle parameters, and obtain the torticollis severity score in the TWSTRS, including five items: 1) maximal excursion (including six sub-items: rotation, laterocollis, anterocollis, retrocollis, lateral shift, and sagittal shift), 2) duration factor, 3) shoulder elevation, 4) range of motion, and 5) time. This low-cost system provides a valuable clinical tool for the diagnosis, assessment and even telemedicine of cervical dystonia. Currently, we are cooperating with the Department of Neurology of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine in China to carry out further clinical tests.

Automated segmentation system for pancreas and pancreatic cancer

None

Accurate segmentation of the pancreas and pancreatic cancer is essential for various clinical studies, diagnosis and surgical treatment. However, due to the high anatomical variability, tiny volume and ambiguous borders, the pancreas and its lesions are recognized as one of the most challenging abdominal tissues for segmentation. Moreover, manual annotation is not only time-consuming and laborious, but also places high demands on the professional experience of the annotator, which will impose a huge burden on clinicians. To address this issue, we developed an automated segmentation system for pancreas and pancreatic cancer. It provides excellent generalization capabilities for fully automated segmentation on multiple modalities (such as CT and MRIs), multiple phases (such as venous-phase CT and non-contrast CT) and multi-center datasets. Moreover, we integrated the interactive functions, allowing users to update the segmentation results manually. This system is expected to provide efficient and stable tissue localization and segmentation support for pancreatic cancer clinical diagnosis and treatment (e.g., early diagnosis, surgical planning, surgical robotics, and radiotherapy).

Machine Primer Design

None None

Loop-mediated isothermal amplification (LAMP) is a DNA amplification technology performed under isothermal conditions with high specificity, efficiency, and speed [Notomi T, Okayama H, Masubuchi H, Yonekawa T, Watanabe K, Amino N, Hase T: Loop-mediated isothermal amplification of DNA. Nucleic Acids Research 2000, 28:E63-e63, 28(12)]. In this work, we developed an extensible program, which is designed as a flexible tool for LAMP primer design, and it can meet various design requirements in a high-throughput informatics environment. Considering the characteristics of Golang, such as high running efficiency, native high concurrency and powerful fault-tolerant mechanism, our program is completely implemented in Golang to achieve high throughput analysis based on multithreading. Besides, Golang can be deployed on each major operating system (Windows, Linux, Mac), so this program can be easily switched between different platforms.
