CT Scan
Overview of CT Scan
A computed tomography (CT) scan uses X-rays to make detailed pictures of structures inside of the body.
During the test, you will lie on a table that is hooked to the CT scanner, which is a large doughnut-shaped machine. The CT scanner sends X-ray pulses through the body area being studied. Each pulse lasts less than a second and takes a picture of a thin slice of the organ or area. One part of the scanning machine can tilt to take pictures from different positions. The pictures are saved on a computer.
A CT scan can be used to study many parts of your body, such as the chest, belly, pelvis, or an arm or leg. It also can take pictures of body organs, such as the liver, pancreas , intestines , kidneys, adrenal glands , lungs, and heart. It also can study blood vessels, bones, and the spinal cord. Fluoroscopy which uses a steady beam of X-ray to look at parts of the body and movement within the body may also be done during a CT.
An iodine dye ( contrast material ) is often used to make structures and organs easier to see on the CT pictures. The dye may be used to check blood flow, find tumors, and look for other problems. Dye can be put in a vein ( IV ) in your arm, or you may drink the dye for some tests, or the dye may be put into other parts of your body (such as the rectum or a joint), to see those areas better. CT pictures may be taken before and after the dye is used.
We believe that everyone has the right to the highest level of care everywhere. The right to premium diagnostic capability. The right to excellent image quality and advanced applications. Designed to meet the needs of radiologists, technologists, administrators, and most of all patients, the GE HiSpeed Series can help you provide a new level of care.
GE HiSPeed Scanners
At the heart of the HiSpeed scanners is the patented GE HiLight detector. The result of many years of research and development, the HiLight detector provides outstanding image quality at the lowest dose allowing you to do more, thinner slices.
The HiLight detector delivers 99% absorption of x –rays and better image quality with no post patient collimation.
Superior image quality is also delivered on the HiSpeed systems with Advanced Artifact Reduction (AAR) – Advanced imaging algorithm that significantly reduces artifact caused by oval shape and has large x-ray attenuation differences. This is effective for aged patients who cannot hold arms during exam, shoulder area, CT-AP and so on.
The HiSpeed Series has a very user friendly design from the console to the gantry in order to help you increase the productivity of the department .
The HiSpeed series has been designed to enhance your day-to-day productivity and efficiency.
Completely protocol-driven, the system is simple and intuitive, allowing the technologist to spend more time with the patient, setting up subsequent exams, or responding to additional requests.
True multi-tasking environment with automated real-time processing. The true definition of simultaneity.
Scan a wider range of patients comfortably and easily, with improved productivity, patient comfort and diagnostic efficiency. Compact system design, for ease of siting and easy patient access. Wide, comfortable table with a 400 lb weight limit, allows you to scan a larger, more varied population.
GE’s automate breathing lights allows patients to easily understand breathing/ breath-hold timing and remaining time from a visual display. This is especially helpful for those patients that have a hard time holding their breath or those that have difficulties understanding the language.
Designed for Technological Leadership & Dose Optimization
HiLight Detectors
The result of many years of research and development, the HiLight detector provides industry-leading image quality at the optimum dose allowing you to do more, thinner slices.
Advanced Artifact Reduction
GE’s proprietary reconstruction algorithm, reduces streak artifacts caused by patient’s arms downward in the scan plane.
Auto mA
Reduced unecessary patient dose by maintaining the same IQ level by location of the body.
Beam Tracking
Collimation keeps focal spot shadow over all cells at all times providing real-time X-ray follow-up, guaranteeing that the highest spatial resolution is reached with no post-patient collimation and no dose penalty
Short Geometry
The shorter tube to detector distance reduces the amount of dose given to the patient.
No X-Ray Post-Patient Collimation
All of the beam collimated hits the detectors used to create image… no wasted dose
Display of Estimated Dose (mGy)
CTDIvol display during scan prescription provides patient dose information to the operator
