Prostate Ultrasound Image Processing

چکیده

Prostate cancer is the second most common cancer found in men in the United States and a leading factor in cancer-related deaths. It is a major health issue causing a dramatic impact on the lifestyle of elderly men. Treatment is, however, available, but most successful when the cancer is in an early stage; treatment of an advanced cancer, especially if the spread is beyond the prostate, can be very complex and in many cases incurable. To find the cancer still in an early stage it important for men over the age of 50 to get an annual screening. Presently, several different screening techniques are used to diagnose the presence of the prostate carcinoma, the most common of which are digital rectal examination (DRE), prostate specific antigen (PSA) test and transrectal ultrasound (TRUS). In cases where the presence of cancer is highly suspicious, a biopsy usually follows the screening to fully confirm the diagnosis.

A molecular image-directed, 3D ultrasound-guided biopsy system for the prostate

Systematic transrectal ultrasound (TRUS)-guided biopsy is the standard method for a definitive diagnosis of prostate cancer. However, this biopsy approach uses two-dimensional (2D) ultrasound images to guide biopsy and can miss up to 30% of prostate cancers. We are developing a molecular image-directed, three-dimensional (3D) ultrasound image-guided biopsy system for improved detection of prost...

Interactive prostate shape reconstruction from 3D TRUS images

This paper presents a two-step, semi-automated method for reconstructing a three-dimensional (3D) shape of the prostate from a 3D transrectal ultrasound (TRUS) image. While the method has been developed for prostate ultrasound imaging, it can potentially be applicable to any other organ of the body and other imaging modalities. The proposed method takes as input a 3D TRUS image and generates a ...

Monte Carlo despeckling of transrectal ultrasound images of the prostate

In this paper, a novel stochastic method is developed for despeckling transrectal ultrasound (TRUS) images of the prostate. By incorporating the circular probe acquisition particularities and speckle noise statistics of TRUS images of the prostate into a likelihood-weighted Monte Carlo estimation scheme, the proposed method can better remove speckle noise while preserving image structures and d...

Ultrasound-fluoroscopy registration for prostate brachytherapy dosimetry

Prostate brachytherapy is a treatment for prostate cancer using radioactive seeds that are permanently implanted in the prostate. The treatment success depends on adequate coverage of the target gland with a therapeutic dose, while sparing the surrounding tissue. Since seed implantation is performed under transrectal ultrasound (TRUS) imaging, intraoperative localization of the seeds in ultraso...

3D Needle Shape Estimation in TRUS-Guided Prostate Brachytherapy Using 2D Ultrasound Images

In this paper we propose an automated method to reconstruct the 3D needle shape during needle insertion procedures using only 2D transverse ultrasound (US) images. Using a set of transverse US images, image processing and random sample consensus (RANSAC) is used to locate the needle within each image and estimate the needle shape. The method is validated with an in-vitro needle insertion setup ...
