Universal Diagnostic X-Ray Radiography System
R°SHER-K

PRESCRIPTIONS
Universal Diagnostic X-Ray Radiography System R°SHER-K is designed for operation in hospital’s radiography rooms. It is used for following investigations: bony tissue, chest, lungs, in pediatric, traumotology, myelography, gastroenterology, in surgery, urology, gynecology, digital angiography. This system is offered in two variants: 1) in traditional kind – with using of film technologies and 2) in digital kind – with using of digital chamber to obtain radiography images or with appliance of Cr-structure.

It includes:

Universal Diagnostic table with Tube Stand with the remote control: 

• Functionally it is able to replace the X-Ray complex for three operators. X-rays operator is able to fulfill all kinds of investigations as from distance as from the control panel on the table.
• Remote control is made using the modern technology “Full Operating Console”. It helps to manage by TV post operation, by parameters of exposure and then to process an obtained digital images.
• Capability to work with URI along the edge of table (urology and gynecology investigations).
• Easy  approach to patient from any side (examinations with the color substances).
• The Power dose in distance of 1 m from the focus (dispersion of radiation) doesn’t exceed 1 mHr/h at anode voltage of 100kV.
• To install this equipment the space of 25sq.m is enough.

To guarantee the maximum safety work, high durability and the capability of equipment’s technical control and the function of self diagnostics, all functions of R°SHER-K are managed by microprocessor.

The table for investigations:

• To make an equipment totally symmetrical, the table with the pitch of  90º/90º was designed. Thanks to this feature, the stop for foots can be set on the both sides of the table to the wish of the user. It depends of the disposition relating to entrance to the room and the defense bar.

Deck of the table:

• The deck of the table can be made of wooden layers or from carbide fiber to the choice of customer. The flat or cave surfaces are also available. In any choice the material of table guarantees   minimum distance from the deck of the table to the film; besides, there are lateral constructions of anode aluminum and they are equipped with guiders for accessories to avoid  any possibility to gather the liquids and they are spread under the surface of table.
• The distance from the floor to the deck of the table is from 76cm to 100 cm. The positioning of the upper table is flexible: 34cm in cross-beam direction, the variant to travel the deck of table on the distance of 95cm in previously fixed longitudinal direction.

The Post of X-ray Tube:

• The wide possibility for the post positioning provides the high flexibility use of the system.
• Longitudinal movement:

- 124cm - without longitudinal movement of the deck;
- 108cm - with longitudinal movement of the deck

• The distance - “focus-film”.

Variable distance “focus-film” in the condition of uninterrupted work with previously selected points of 115cm, 135cm and 150cm gives the possibility to get the images of high quality during cardiology and lugs examinations.

• X-ray Tube’s Assembly’s rotation:

- Due to turning to 180º the exposures on vertical installation and on stretchers are possible.
- Due to turning to -18º X-ray exposures with the cassette out of assembly (for example, exposure of extremities) are possible.

• The minimum distance between the pencil of rays and the edge of table: 43cm makes easy the carrying out of urology and gynecological examinations. Thanks to the special design, the table in vertical position provides the high effective diagnostics and investigations of:

- Patients with the severe displacements in extremities due to diminished distance “focus-floor”.
- Patients in straighten position due to large longitudinal positioning and large focus distance. For positioning, operator is able to use the large “focus-floor” distance and wider space.

Assembly of Aimed Film Station System – UPR

UPR – is totally automated and due to its high universal capability it can be used with cassettes of various sizes from 18x24cm to 35x43cm, with capability of vertical dividing into 2, 3 or 4 parties. 
Besides, you can select the system of remote control (in the version of T90cex), providing the capability of horizontal dividing into 4 and 6 parts for cassettes with sizes 18x24cm, 24x24cm and 24x30cm.
Universality of UPR is raised due to the capability of deleting the telescopic grid.

Collimator

Collimator is equipped with the system of  light centering which helps to execute the adjustment in two regimes:

• Manual;
• From the control panel;
• Automatically - according to the cassette’s divisions, UI field and “focus-film” distance.

Collimator is available with:  rectangle field or with rectangle and iris field. It can be useful while using the digital system.

Control Panel

The Control Panel processes signals from the table and the generator. The Control Panel is equipped with the keyboard of the digital system (where it is foreseen). Operator uses the single control panel for all commands constructed according the single functional and ergonomic logic. These aspects provide the priorities in operation, compact ability, esthetic view . The Control Panel can be installed on the correspond post of bearing on the floor or on the table.
