Automatic Bone Segmentation in Ultrasound Using Combined Strain Imaging and Envelope Signal Power

چکیده
In computer assisted orthopaedic surgery (CAOS), fluoroscopy remains the primary intraoperative imaging modality for bone boundary visualization. However, the associated radiation exposure poses risks to both patients and surgical teams. Ultrasound (US) imaging has thus recently emerged as a safer (non-ionizing) potential alternative intraoperative imaging modality; in recent years, our group has introduced and evaluated a set of techniques based on phase symmetry processing for accurately identifying bone surfaces in 2D and 3D ultrasound images (Hacihaliloglu 2011, 2012, 2014, Brounstein, 2011).

Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...
متن کاملAn Improved Automatic EEG Signal Segmentation Method based on Generalized Likelihood Ratio
It is often needed to label electroencephalogram (EEG) signals by segments of similar characteristics that are particularly meaningful to clinicians and for assessment by neurophysiologists. Within each segment, the signals are considered statistically stationary, usually with similar characteristics such as amplitude and/or frequency. In order to detect the segments boundaries of a signal, we ...

Introduction: Modern radiotherapy (RT) techniques allow a highly precise deposition of the radiation dose in tumor. So, high conformal tumor doses can be reached while sparing critical organs at risk. Materials and Methods: This study was conducted in three phases. In the first phase; Fourteen patients with primary or recurrent prostate cancer receive Gallium-...
متن کاملAn Information Fusion Method for the Automatic Delineation of the Bone-Soft Tissues Interface in Ultrasound Images
We present a new method for delineating the osseous interface in ultrasound images. Automatic segmentation of the bone-soft tissues interface is achieved by mimicking the reasoning of the expert in charge of the manual segmentation. Information are modeled and fused by the use of fuzzy logic and the accurate delineation is then performed by using general a priori knowledge about osseous interfa...
