  Transcranial Magnetic Stimulator What is Transcranial Magnetic Stimulation? Transcranial magnetic stimulation (TMS) is a noninvasive treatment that uses magnetic fields to stimulate nerve cells in the brain. During TMS, magnetic pulses are delivered through a coil placed near the scalp to target specific areas of the brain associated with the condition being treated. These pulses generate weak electric currents that stimulate nerve cells in the targeted regions. TMS was approved by the U.S. Food and Drug Administration in 2008 for treating medication-resistant major depression. Since then, its use has expanded to other neurological and psychiatric disorders. How Does TMS Work? When the TMS coil generates a magnetic pulse near the scalp, it induces an electric current in the region of the brain immediately underneath the coil. The intensity of stimulation can be precisely controlled. Repeated pulses are delivered in sessions that typically last around 30 minutes. Most treatm...

Shutter Image Sensor Ever since the invention of the first photographic camera, camera technology has evolved dramatically over the years. From film cameras to digital cameras, the underlying image sensor technology has played a crucial role in enabling new photographic capabilities and higher image quality. History of Camera Sensors The earliest cameras used light-sensitive chemicals on glass plates or photographic film to capture images. These chemical-based sensors could only capture a single image at a time as each exposure completely erased the previous image. The introduction of CCD and CMOS digital image sensors in the late 20th century allowed cameras to capture, store and playback multiple digital images electronically. However, these early digital sensors still relied on a mechanical shutter to control the exposure time. The shutter would have to open and close very quickly to capture each photo, placing limitations on speed, resolution and other capabilities. The Dawn ...

Non-PVC IV Bags Health Concerns with PVC Use in Medical Devices Polyvinyl chloride (PVC) has been the industry standard plastic used to manufacture intravenous (IV) bags and tubing for administering fluids, medications and blood products to patients. However, concerns have been rising regarding the safety of PVC due to potentially harmful compounds that can leach out of the plastic over time.
