background: lymphedema is a common complication for breast cancer therapy. patients with lymphedema may experience pain and body image issues. this study investigates the effect of combined decongestive therapy and pneumatic compression pump on body image in patients with lymphedema secondary to breast cancer treatment. methods: 42 women with breast cancer related lymphedema partici...
Background and purpose: Image quality together with low patient dose is two important goals in radiography procedures. Acquire radiographic images with inadequate quality give rise to uselessly patient dose, improper diagnosis, waste the cost and impose the biological effect to the patients. In this study image quality was evaluated for most common radiographic procedures based on indentified i...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
An improved pixon-based method is proposed in this paper for image segmentation. In thisapproach, a wavelet thresholding technique is initially applied on the image to reduce noise and toslightly smooth the image. This technique causes an image not to be oversegmented when the pixonbasedmethod is used. Indeed, the wavelet thresholding, as a pre-processing step, eliminates theunnecessary details...
Image restoration is an essential preprocessing step for many image analysis applications. In any image restoration techniques, keeping structure of the image unchanged is very important. Such structure in an image often corresponds to the region discontinuities and edges. The techniques based on partial differential equations, such as the heat equations, are receiving considerable attention i...
In recent years steganography has attracted the attention of many researchers. Steganography can be used in media such as still image, audio, and video. Image is one of the most frequently used media. One of the forms of presentation of an image is halftone. In this paper a method is presented which hides data in halftone images. The data hiding process is performed during the halftoning step. ...
Background: Medical image interpolation is recently introduced as a helpful tool to obtain further information via initial available images taken by tomography systems. To do this, deformable image registration algorithms are mainly utilized to perform image interpolation using tomography images.Materials and Methods: In this work, 4DCT thoracic images of five real patients provided by DI...
background: due to the increased growing heart diseases and necessity to do heart surgery, as well as the importance role of rehabilitation in reducing patient’s mortality, patient’s promotion body image and quality of life should be proposed as one of the main goals of treatment interference. this research was performed with the goal to identify the process of rehabilitation period on the ch...
