Spiral ct can achieve improved image resolution for a given radiation dose compared to individual slice acquisition.

Slip ring technology in ct radiology.

Slip rings are electromechanical devices consisting of circular electrical conductive rings and brushes that transmit electrical energy across a moving interface. Other ct technologies have been adapted to third and fourth generation scanners including. With helical ct the patient is moved through a rotating x ray beam and detector set. A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure.

Dual energy ct scanning. From the perspective of the patient the x ray beam from the ct traces a helical path. Third and fourth generation scanner technologies are both used in many health care. 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.

All power and control signals from the stationary parts of the scanner system are communicated to the rotating frame through the slip ring. Slip ring technology made helical acquisition possible. 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.

It can improve mechanical performance simplify system operation and eliminate damage prone wires dangling from movable joints. Helical spiral ct image acquisition was a major advance on the earlier stepwise stop and shoot method. Large diameter slip rings are ideal for better working of the computed tomography machines. With the ever increasing data speed requirements of multi slice machines an alternative method of handling data across the rotating interface is required.

Slip ring technology enables production of improved images and better diagnostic functionality of the machine. Located inside the gantry the slip ring technology allowed the tube to continue to rotate without the need to rewind. Helical spiral image acquisition. 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.

Used in all modern ct machines. Basics the transmission of power across a large free inner bore is one of the key factors in a rotating system. Most modern hospitals currently use spiral ct scanners. Slip ring tecnology 2.

The use of slip ring technology in ct scans has dramatically improved the accuracy and efficacy of this diagnostic scanning process.
