We report on a new articular cartilage imaging technique with potential for clinical arthroscopic use, by supplementing the variable-incidence-angle polarization-sensitive optical coherence tomography method previously developed by us with a conical beam scan protocol. The technique is validated on bovine tendon by comparing experimental data with simulated data generated using the extended Jon...

Digital Object Identifier: 10.1188/03.CJON.697-698 Mr. M is a 75-year-old man recently diagnosed with chronic lymphocytic leukemia. The first two courses of chemotherapy were administered without problems, and Mr. M said he was feeling well enough to continue the remodeling of his home. While undergoing his third course of chemotherapy, he returned to the outpatient clinic with neutropenia, fev...

Although it has been considered a safe procedure, computed tomography scanning uses high doses of radiation and can cause malfunctioning in those patients with ICD when the radiation is directly incident on the device. We present a case of ventricular oversensing during a thoracic computed tomography.

In this article , the authors introduce a case of Caroli's Disease (CD) according to the results of ultrasonography (U.S), abdominal computed tomography (CT scan) and hepatic biopsy that has been manifested in the neonatal period. In the routine examination of the neonate, abdominal protrusion was noticed. Then milk intoterance, inability of meconium passage and vomiting developed, during w...

Computerized axial tomography using the EMI scanner as a new method of using x-rays in diagnosis. The technique displays intracranial and orbital structures in the transverse plane. The appearances of normal EMI Scans are described and correlated with cerebral and orbital anatomy seen in transverse section.

The diagnosis of pulmonary embolism may be confounded by a clinical presentation that is often subtle or atypical. Therefore pulmonary angiography, although invasive, has been widely used to prove pulmonary embolism. The aim of this review is to discuss the value of non-invasive techniques, such as lung scan and chest computed tomography scan, in the diagnosis of pulmonary embolism. Ventilation...

Computer aided technologies, medical imaging, and rapid prototyping has created new possibilities in biomedical engineering. The systematic variation of scaffold architecture as well as the mineralization inside a scaffold/bone construct can be studied using computer imaging technology and CAD/CAM and micro computed tomography (CT). In this paper, the potential of combining these technologies h...

Covid-19 infection, which first appeared in Wuhan, China December 2019, affected the whole world a short time like three months. The disease caused by virus called SARS-CoV-2 affects many organs, especially lungs, brain, liver and kidney, causes large number of deaths. Early detection using computer-aided methods will ensure that patient reaches right treatment without wasting time, spread be c...
