In this paper, current research towards an automated micro/nano handling station using mobile microrobots is presented. Mobile microrobots with piezo slip-stick actuation and more than one degree of freedom mostly don't have internal pose sensors; therefore a global sensor is needed. This paper focuses on the pose estimation of the mobile microrobots. One possibility for fast pose estimation is...

In the medical field, Image processing methods are widely used. It is a method for the improvement of image, the image which is obtained after processing is useful for earlier detection and various stages of cancer. In cancer tumors such as lung cancer time factor is the important key point because in the targated images of lung cancer time factor is use to discover the abnormality. Basically t...

BACKGROUND Despite its superb lateral resolution, flat-panel-detector (FPD) based tomosynthesis suffers from low contrast and inter-plane artifacts caused by incomplete cancellation of the projection components stemming from outside the focal plane. The incomplete cancellation of the projection components, mostly due to the limited scan angle in the conventional tomosynthesis scan geometry, oft...

Background: Photon attenuation as an inevitable physical phenomenon influences on the diagnostic information of SPECT images and results to errors in accuracy of quantitative measurements. This can be corrected via different physical or mathematical approaches. As the correction equation in mathematical approaches is nonlinear, in this study a new method of linearization called ‘Piece ...

Hearing loss is a common chronic condition among older adults. The most common form is sensorineural hearing loss, which is caused by damage to the hair cells of the inner ear. Physicians have little ability to reliably access the complex anatomy of the inner ear and thus are unable to cure the most common forms of hearing loss. Two generations of an image-guided robotic system for targeted, at...
