There are growing expectations for AI computer-aided diagnosis: diagnosis (CAD) systems can be used to improve the accuracy of diagnostic imaging. However, it is not easy collect large amounts disease medical image data with lesion area annotations supervised learning CAD systems. This study proposes an unsupervised local feature extraction method running without such datasets. Local features o...

With the rapid development of computer technology and the successful Application of medical imaging, computer aided diagnosis technology develops increasingly. On the basis of the research and analysis of cerebral aneurysm and DSA imaging mechanism, this paper proposed a cerebral aneurysm recognition method using Bayesian classification. After cerebral vessel image is preprocessed, geometrical ...

objective(s): bonenavi, a computer-aided diagnostic system, is used in bone scintigraphy. this system provides the artificial neural network (ann) and bone scan index (bsi) values. ann is associated with the possibility of bone metastasis, while bsi is related to the amount of bone metastasis. the degree of uptake on bone scintigraphy can be affected by the type of bone metastasis. therefore, t...

The female flea Tunga penetrans is responsible for a cutaneous parasitosis known as Tungiasis. We report the clinical case of a 12 year-old Caucasian boy who sought treatment in a dermatological private office due to a painful lesion in the plantar area and whose dermoscopic examination, without skin contact, allowed the visualization of parasite's movement inside the skin. The diagnosis of tun...

background omental cysts are rarely intra-abdominal pathology. we report a case of omental cyst successfully resected by laparoscopy using two ports only with excellent outcome. case presentation our patient was a seven year old girl who presented with complaints of lump in abdomen, in which laparoscopy aided in making a correct final diagnosis and the surgical management. preoperative diagnost...

We present a system for computer aided diagnosis of bone tumors in the facial skeleton. There are many di erent lesions with radiographic manifestation in the jaws. Our system helps performing the di erential diagnosis of these. The input is a digitized orthopantomograph (OPG) in which the user marks the position of the lesion with a single mouse click. An active contour model then automaticall...

Due to some important properties of B ezier splines, they have great potential use in computer-aided mammogram diagnosis. In this paper, B ezier splines are applied in both lesion detection and characterization processes, where lesion detection is achieved by segmentation using a natural threshold computed from B ezier smoothed histogram; and lesion characterization is achieved by measuring the...
