The “Cox” Maze
Dr. James Cox developed a procedure called the “Cox maze” in 1987, that has changed from the “cut and sew” surgical procedure, where there were several cuts made to create a maze, to a use of surgical ablation technology, where ablation lesions are put with different energy sources such as radiofrequency, cryothermy, microwave, and high-frequency ultrasound. Therefore, this course of action has evolved from a median sternotomy choice to one that can be done minimally, invasively, and robotically. (Henry, 2013)

It’s a concern for patients and their radiation dosages when they have lifelong imaging needs with chronic disease. There is an advanced clinical cardiac CT scanner recently available. It is a second-generation, dual-source scanner that offers high-spatial resolution of a modern CT, the high-temporal resolution of dual-source technology, and the wide z-axis of modern cone-beam CT scanners. With this new and improved technology, it reduces scan time, reduces the exposure to radiation, and enlarges the imaging of a cardiac CT. There is evidence that when patients with adult congenital heart disease get a CT scan by a second-generation dual-source scanner, there are low-radiation dosages and clear and concise image quality. (Ghoshhajra, et al., 2012)

Medtronic’s O-arm Multidimensional Imaging System

There are several hospitals using different surgical imaging technology. For example, Via Christi on St. Francis has bought and activated a surgical imaging system that is high-tech and advanced enough for surgeons use while working through spinal surgeries. This high-tech and advanced imaging system is called Medtronic’s O-arm Multidimensional Imaging System. Patients at the Wichita hospital get faster, safer, and accurate placement of spinal implants as a result. This lowers the risk for implant-related problems and returns to the OR for a reposition. ““It makes me feel more confident in what I do,” said Michael Chang, MD, PhD, FAAOS, an orthopedic spine surgeon at Via Christi Clinic and the first to use the system at Via Christi. “Plus, it ultimately may lead to faster recoveries and improved outcomes for patients.””. The O-arm Imaging System was designed specifically to be used in the OR by providing complete multidimensional, intraoperative surgical imaging, surgeons with real-time, three-dimensional images, and also multiplane two-dimensional and fluoroscopic imaging. Spine surgeons can view the patient’s bodily reaction in the operating room, keep an eye on the surgery and its status, and note any changes with a 3-D image while the patient is still in a surgical state. Some of the things that make the O-arm easier than previous technology or ways is its navigation on the computer, which helps guide placement of an implant by it providing real-time and live imaging, and the capability of CT scanning that helps to also verify optimal placement. The O-arm in all reduces the amount of radiation exposure greatly for the surgeons and operating room staff. They can remove themselves from the patient’s room while images are being taken. If not with computer navigation, they must be taken while the operation is being done. The O-arm Imaging System that was received with an FDA clearance in 2006, was created for orthopedic operations but has...

Another form of digital radiography is direct radiography in which a sensor converts x-ray energy into electrical signals” (Bansal, 2006). “In digital imaging phosphor plates are two to four times faster than film screens. A higher efficiency implies a lesser dose of x-rays required. The image quality in a digital system depends on the quality of the x-ray equipment, applied dose, pixel size and depth, signal to noise ratio, and
