A Short Introduction to Clinical Photography for the Plastic Surgeon

A Short Introduction

Microsurgery not only means working with the help of a surgical microscope. One of themajor advantages lies in the possibility to perform operations through small skin incisions (“keyhole surgery”). This needs meticulous preoperative planning, exact positioning of the patient, and reliable localization of the surgical target area in projection to the entry level on the skin surface. All these f...

Run-DMA

Copying data from devices into main memory is a computationally-trivial, yet time-intensive, task. In order to free the CPU to perform more interesting work, computers use direct memory access (DMA) engines — a special-purpose piece of hardware — to transfer data into and out of main memory. We show that the ability to chain together such memory transfers, as provided by commodity hardware, is ...
