Fractional-order Darwinian PSO-based feature selection for media-adventitia border detection in intravascular ultrasound images.

Media-adventitia (MA) border delineates the outer appearance of arterial wall in intravascular ultrasound (IVUS) image. The detection of MA border is a challenging topic due to many difficulties such as complicated intravascular structures, intrinsic artifacts and image noises. We propose a classification-based MA border detection method with an embedded feature selection technique.

Multifocal skeletal tuberculosis: experience in diagnosis and treatment.

Objectives: Multifocal skeletal tuberculosis (MSTB) is an uncommon presentation of skeletal tuberculosis. In order to provide more clinically meaningful information on the diagnosis and management of MSTB, we present a case of MSTB with multiple tuberculous lesions in multiple locations, along with a review of 13 MSTB cases from different studies.

Patients And Methods: A 29-year-old male patient with a one-year history of back pain was initially diagnosed with ankylosing spondylitis and arthritis deformans, and received treatment with oral glucocorticosteroid and leflunomide for 24 weeks.

[Design and development of the DSA digital subtraction workstation].

According to the patient examination criterion and the demands of all related departments, the DSA digital subtraction workstation has been successfully designed and is introduced in this paper by analyzing the characteristic of video source of DSA which was manufactured by GE Company and has no DICOM standard interface. The workstation includes images-capturing gateway and post-processing software. With the developed workstation, all images from this early DSA equipment are transformed into DICOM format and then are shared in different machines.

[Design and implementation of a system for transforming the NEMA 2.0 images into DICOM 3.0 images].

This paper introduces the design and implementation of a system which can get the NEMA2.0 image data from the hard disks of the imaging equipments directly,then analyzes and transforms these image data into the DICOM3.0 image data and sends them to the image server.
