A scanning unit, also known as a gantry, is the structure that contains the X-ray tube, shielding elements, and photon detectors. The X-ray tube and photon detectors are positioned to face each other and are built to rotate 360 degrees in one direction around the patient. 1, record 1, English, - scanner%20gantry

One disadvantage of this geometric design is that the system must be reset after only two complete revolution of the x-ray tube. This is due primarily to the arrangement of the cables within the gantry. It can be seen that there is a time delay between periods when the x-ray tube is activated. This is referred to as the interscan delay(ISD). 1, record 2, English, - interscan%20delay

Helical Acquisition... In this approach, image acquisition time is decreased significantly by connecting the tube voltage cables through a "slip ring, "a sliding contact mounted on the rotating gantry of the unit. With slip-ring technology, the X-ray tube rotates while the patient table moves without stopping. Hence, the patient is moved continuously through the gantry during the study, and the X-ray beam maps out a helical path in the patient... 3, record 3, English, - helical%20acquisition

Percutaneous coronary intervention(PCI) is a treatment for persons experiencing myocardial ischemia(inadequate blood flow to the heart) or myocardial infarction(heart attack).... Under x-ray guidance, a catheter is threaded through the femoral artery up into the aorta(large artery from the heart) and then gently advanced into the affected coronary artery. There, a balloon is used to open the coronary artery(balloon angioplasty) and restore blood flow. Sometimes a stent(a mesh-like metal tube that holds open the artery) is placed at that time to maintain good blood flow through the damaged area. 2, record 7, English, - percutaneous%20coronary%20intervention

As the x-ray tube and detector make this 360° rotation, the detector takes numerous snapshots(called profiles) of the attenuated x-ray beam. Typically, in one 360° lap, about 1, 000 profiles are sampled. Each profile is subdivided spatially(divided into partitions) by the detectors and fed into about 700 individual channels. Each profile is then backwards reconstructed(or "back projected") by a dedicated computer into a two-dimensional image of the "slice" that was scanned. 8, record 15, English, - computerized%20axial%20tomography

Record number: 20, Textual support number: 1 OBS
This is accomplished when an X-ray tube is connected directly to the secondary windings of the high voltage transformer without any intervening rectifier. When the cathode is negative with respect to the anode, electrons will flow from the cathode filament to the anode and produce X-rays. During the next half of the electrical cycle, the anode is negative with respect to the cathode, and electrons could flow in the opposite direction. However, as long as the anode is kept cool, no electrons will be emitted from the anode, and no current will flow. The result is that of half wave rectification, where only half of the cycle of the high-voltage current is used to produce X-rays. 1, record 20, English, - self%2Drectifying%20tube
Record number: 20, Textual support number: 2 OBS
An obvious disadvantage of self-rectification, as opposed to supplying the X-ray tube with an already rectified direct current, is that exposure times must be increased since X-ray production occurs during only half of the time the current is applied. Secondly, repeated exposures could heat the anode to such an extent that electrons are also emitted from the anode. This could result in a reverse flow of electrons in the X-ray tube with excessive heating and destruction of the filament. 1, record 20, English, - self%2Drectifying%20tube

L'innovation la plus importante de la fin des années 1920 concerne sans nul doute l'introduction des tubes à anode rotative. En 1915, Coolidge avait déjà envisagé de construire un tube à anode tournante, sans pour autant aboutir à un résultat satisfaisant. C'est le physicien Albert Bouwers, chercheur de la firme Philips qui réussit en 1929 à présenter le premier tube à anode rotative, utilisé en téléradiographie. La rotation d'un disque anodique favorise le refroidissement et permet d'appliquer une charge beaucoup plus importante dans un laps de temps plus réduit. Le disque est entraîné par un petit moteur à induction dont la rotation se situe entre 3000 et 9000 tours-minute. 3, record 22, French, - tube%20%C3%A0%20anode%20tournante
