Slip Ring Technology In Ct Radiology

Most modern hospitals currently use spiral ct scanners.

Slip ring technology in ct radiology.

Continuous rotation of the tube and detectors coupled with continuous movement of the table and patient through the gantry are the basic components of spiral helical ct figure 16 5. Dual energy ct scanning. Slip ring tecnology 2. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals.

From the perspective of the patient the x ray beam from the ct traces a helical path. Slip rings are electromechanical devices consisting of circular electrical conductive rings and brushes that transmit electrical energy across a moving interface. Slip ring technology in conventional ct scanning there was a paused between each gantry rotation. Third and fourth generation scanner technologies are both used in many health care.

Used in all modern ct machines. Spiral ct can achieve improved image resolution for a given radiation dose compared to individual slice acquisition. It can improve mechanical performance simplify system operation and eliminate damage prone wires dangling from movable joints. Large diameter slip rings are ideal for better working of the computed tomography machines.

Helical spiral image acquisition. With the ever increasing data speed requirements of multi slice machines an alternative method of handling data across the rotating interface is required. A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. Located inside the gantry the slip ring technology allowed the tube to continue to rotate without the need to rewind.

Slip rings are electromechanical devices consisting of circular electrical conductive rings and brushes that transmit electrical energy across a moving interface. In the earliest ct scanners this data transmission task was accomplished with a slip ring i e sliding electrical contacts. The 1980s saw a significant advancement in technology with the introduction of slip rings which eliminated the need for a high tension cable supply to the x ray tube and detectors and allowed the x ray tube to rotate continuously in one direction around the patient. Helical spiral ct image acquisition was a major advance on the earlier stepwise stop and shoot method.

Basics the transmission of power across a large free inner bore is one of the key factors in a rotating system. This is known as spiral or helical ct. With helical ct the patient is moved through a rotating x ray beam and detector set. Slip ring technology made helical acquisition possible.

Other ct technologies have been adapted to third and fourth generation scanners including.
