Todays, the bill counter is being upgraded to an intelligent banking machine involving various functions such as bill type recognition, counterfeit detection, automatic summation as well as automatic binding. In order to make these possible, we need an efficient number recognition algorithm just for bill counter. This paper explains proposed algorithm and shows that this algorithm makes it possible to recognize the bill types while the bill counter counts in superhigh speed.

Multiple cavernous hemangiomas with fluid-fluid levels were presented in a 40-year-old male patient. These hemangiomas showed nonspecific radiologic features on ultrasound and computed tomography, but gadolinium-enhanced magnetic resonance imaging (MRI) with subtraction revealed fluid-fluid levels with unique and different enhancement of the inferior and superior layer. This is the first case report of cavernous hemangiomas with fluid-fluid levels, containing radiologic features of dynamic MRI with subtraction.

Phyllodes tumor of the breast is a relatively rare fibroepithelial tumor. Turner syndrome is a condition that affects approximately 50 per 100,000 females and includes total or partial absence of one X chromosome in all or part of the cells, reduced final height, absence of female sex hormone, and infertility. In this case report, we describe the first case of a benign phyllodes tumor mimicking a malignancy at breast US in a 26-year-old woman with Turner syndrome who had been undergoing hormone replacement therapy.
