BACKGROUND Nowadays, ultrasound techniques have not gained importance in the diagnosis and monitoring of lung pathologies yet because of the high mismatch in acoustic impedance between air and intercostal tissues. However, it is evident that B-mode imaging provides important information on pulmonary tissue, although in the form of image artifacts. FINDINGS Notwithstanding medical evidences, t...

Methods Material and method: Focal One is a device designed for the focal therapy of Prostate Cancer combing the necessary tools to visualize, target, treat and validate the focal treatment. MR volumes are imported through the hospital’s network. The operator defines the contours of the prostate and the regions of interests that have been confirmed as prostate tumors. The same contouring of the...

In recent years, still image compression technique plays an important role in many applications such as data transmission and data storage. For speeding up image propagation and reducing image storage efficiently, there are many image compression techniques were proposed. Among them, JPEG2000 is a new generation technique, which can encode images at very low bit-rate with acceptable quality. Be...

Introduction: Diagnosis of primary and secondary cancers to treat patients with diffuse and malignant tumors is an important subject. The appropriate treatment will be eliminating primary and metastatic tumors. Radiofrequency ablation with localized heat induction in the target tissue causes irreversible cellular damage and tissue coagulation. Estimation of tissue temperature c...

Freehand three-dimensional ultrasound system allows intra-operative imaging of pathologic tissue for image-guided injection. Accurate registration of ultrasound image for injection navigation requires calibration that is timeconsuming and tedious. We present an efficient calibration system based on a clinical injector. The injector equipped with an optical tracking sensor is moved in the vicini...

The main purpose of this paper was to introduce an efficient algorithm for fault identification in fruits images. First, input image was de-noised using the combination of Block Matching and 3D filtering (BM3D) and Principle Component Analysis (PCA) model. Afterward, in order to reduce the size of images and increase the execution speed, refined Discrete Cosine Transform (DCT) algorithm was uti...

With the recent advances in the field of computer science and technology and the introduction of image processing as a field of computer science and information technology, enhancement in the interpretation of the medical images has contributed to the early diagnosis of various diseases in human beings. This paper provide the design and implementation of an intelligent system that would be used...

A wavelet-based method for speckle suppression in ultrasound images of the thyroid gland is introduced. The classification of image pixels as speckle or part of important image structures is accomplished within the framework of back-propagation tracking and singularity detection of wavelet transform modulus maxima, derived from inter-scale analysis. A comparative study with other de-speckling t...

Hen’s native chicken reproductive organ health status evaluation is important for raising Indonesian native chicken in order to support protein supply for people demand. This study aimed to discover the images of Indonesian hen’s native chicken reproductive organ using ultrasonography. There were 18 hens that used in this study and divided into two groups, 15 hens for brightnessmode ultrasonogr...
