An X-ray source is on a slide in the table body stored and movable in the longitudinal direction of the table. A spar arrangement is coupled to the sledge, which moves along the table body with the X-ray source. The spar arrangement shows a standing Holm who has an X-ray imaging device in selected divisions above the top of the table. An X-ray table of this type is disclosed in US patent application Ser. No. 656 448 of July 27, 1967.

If the doctor still takes pictures in the form of x-rays too desires to do so, an imaging device, i.e., an X-ray imaging device, is used. Latter presents a film slide at an exposure station in the path of X-rays from an X-ray source carried in the table body, which are currently in use Image pickup devices have an automatic shutter mechanism and a carriage system for moving a film sheet in different positions within the exposure station to selectively the entire film sheet or sequentially to expose selected parts of the film sheet. An image pickup device with a shutter mechanism of this type is disclosed in U.S. Patent 3,502 described. In the image pickup devices used heretofore, a film in a cassette is used. Every Film foil is in a separate cassette. The image recording device has a movable carriage, that takes and sets up a film cassette for exposure. When the exposure is over, the exposed Film cassette removed from the image pickup device and a cassette containing an unexposed film sheet, inserted into the slide for subsequent exposure.

The use of cartridges is with a whole number of

609816/0986

Disadvantages, which include:

a) The cassettes must be loaded individually in the dark and brought into the X-ray room, where they are exposed and returned to a dark environment for taking out and developing. These Individual handling of film foils and relatively heavy cassettes is time-consuming, cumbersome and expensive"

b) A large number of cassettes are required in clinics and the like in which there are a large number of X-ray rooms are in operation and each must be supplied with a film in a cassette.

c) The handling of the cassettes while taking a series of X-ray photographs is cumbersome and time consuming. In addition, each film must be labeled to ensure that the X-ray images not be confused with those of another patient,

d) The cartridges must be handled carefully to prevent light penetrating and exposure To prevent scattered radiation. In the case of storage in an X-ray room, the cassettes must be equipped with a radiation shielding Be provided with envelope.

e) Bad or unusable radiographs can be obtained if the cassette springs, which the Clamp film between two reinforcement screens, break, weaken, or improperly positioned be, the problem of achieving an intimate umbrella /

is necessary is not yet for cassette film systems solved perfectly. This problem may require that if an X-ray is unusable, the patient must be brought back to the X-ray table in order to take part or all of the recordings of a series of X-rays to repeat.

f) The X-ray transmittance of film cassettes varies from cassette to cassette. An uneven one X-ray permeability causes variations in the quality of the X-ray images.

Various types of X-ray machines as the image pickup devices have been proposed in the past made with the aim of avoiding the use of cartridges in order to avoid the problems associated with cartridges turn off. Such proposals provide for the use of separate film storage magazines which the exposed and record unexposed film sheets. The unexposed film sheets are individually from a magazine for unexposed Foils conveyed to an exposure station. The exposed films are from the exposure station brought to a magazine for exposed films.

U.S. patent application Ser.No. 93 268 of November 27, 1970 describes a cassette-less system in which film sheets of different sizes conveyed in storage magazines of different sizes and selecting an exposure station are fed. After exposure, the film sheets are exposed to a common station Films fed. In the system described, a vacuum source is used to provide a complete intimate contact between a film foil and two

609816/0986

-s- 2S4484!

To achieve strengthening screens.

Imaging devices introduce a number of new problems which counteract the use of the previous ones Cassette-less film handling systems in an image capture device speak.

One such problem concerns balance. As an image pickup device movable on the movable Spar of a tiltable X-ray table is mounted, must their weight and the weight of the spar carrying them are carefully balanced so that the image recording device and the spar can be easily moved regardless of the inclination angle of the inclinable table top. the The need for counterbalancing means that the weight of the image pickup device is so light must be kept as possible. In addition, as in the aforementioned US patent application Ser.No, 656 t ^ 8 dated July 27, 1967, every kilogram of the imaging device is not one kilogram, but three kilograms of counterweight. As a result, the weight of the image recording device per kilogram is four kilograms Load must be placed on the table. This additional load requires a further strengthening of the table, whereby a further increase in weight is obtained.

In other words, it adds a little extra weight to the image pickup device, which is very significant in terms of design Problems with yourself. Since the previous cassette-free film systems for use in systems under the Table and the like, where the weight of the system was not a real problem, are the previous ones

609816/0986

ORIGINAL INSPECTCD

2B44848

Systems usually too heavy for an imaging device «,

Another problem faced by film handling or conveying systems peculiar to image pickup devices is that there is limited space for the image pickup device is available. A modern x-ray room has an x-ray source located across the thickness as well as equipped with other facilities used both with and near the X-ray table "In order for proper use of such facilities to be made, the imaging device must be of limited size and must be out of the way in a "park" position when not in use can be brought. The previous cassette-less film conveyor systems are for use with image capture devices not suitable as they are cumbersome and bulky.

Some of the previous film feed systems have been mechanical Sensors used to detect the presence of a film sheet at various locations along a film conveyor track to feel. The problem with using such sensors is that they drag on the film sheet and are undesirable Leaving marks on the film and occasionally disrupting the promotion of the film.

In order to avoid such and the disadvantages described above, the object of the invention is to provide a Image recording device of compact design and relatively to develop low weight, which can be operated in such a way that a rapid, fully automatic conveyance and adjusting the film sheets while taking an X-ray image or a series of X-ray images can be made.

609816/0986

ORIGINAL IMSPECTED

The image recording device according to the invention has a housing which encloses a space in a light-tight manner. The case delimits a chamber of L-shaped cross-section that has a has first relatively narrow elongated region, which in the vicinity of its one end with a second relatively wide area is related. A vacuum-evacuable assembly is movable in the first area arranged. A film feed mechanism is located in the second area.

An orthogonal drive system is provided with separate X- and Y-direction drive motors through which the vacuum-evacuatable Composite from a retracted position near the second area into an exposure station can be withdrawn in the first area. The drive motors are servo-controlled to make the vacuum evacuable Bring the composite into selected positions in order to expose all parts or a sequence of parts of a film sheet, which is included in the network.

The νakuumevakubaren composite has a relatively rigid vacuum plate and a relatively flexible one Base plate on, there are reinforcing screens between the vacuum plate and the base plate. One of the reinforcement screens lies tightly against the base plate, while the other screen lies tightly against the vacuum plate.

The vacuum plate has a circumferential groove that extends into in the circumferential direction around its reinforcing screen. There is a vacuum seal in this groove. The base plate reinforcement screen is larger than that Dimensioned vacuum plate shield and lies against the vacuum

609816/0986

seal on. The vacuum evacuation channel is formed in the vacuum plate and is used to vacuum evacuate the chamber, which is limited between the intensifying screens so that the forces of the ambient air pressure, which act against the vacuum plate and the base plate, are used, an intimate screen-film contact between the intensifying screens and a film sheet arranged between them to manufacture.

The vacuum-evacuable composite is designed so that, when a square sheet of film to the image recording device of standard size is arranged in a vacuum composite, a peripheral edge area or a "lip" of the film itself extends out of the composite. This film lip is used for two purposes. One function of the film lip is there is to obtain a film sheet which can be easily grasped by the film conveying mechanism when the Vacuum evacuable composite is in its retracted position »A second function of the film lip is in it too see that there is a film sheet part to which an identification image can be attached so that the Film can be identified by a patient's name or an identification number.

A light source and an optical system are provided as the film identification system, an identification card, which bears the identification mark for the patient can be inserted into an envelope that is removed from the housing the image pickup device. If a film is brought into the vacuum-evacuable compound, the light source is switched on to illuminate the identification marks. An optical system with two mirrors and a lens creates an image of the indicia on the film lip.

609816/0986

Through one side of the housing of the image recording device, two openings are provided which are used for recording serve from two film magazines to the film feed mechanism, which is carried in the second area of the housing. One Power-operated sliding door is provided for opening and closing the openings.

The film magazines are designed differently. One can carry and dispense unexposed film with foils and the other is used for receiving and conveying film-exposed film. Each of the magazines is with one movable cover which is latched when the magazines are removed from the film feed mechanism.

The film feed mechanism includes several powered ones Sub-units that are used to:

1) to grasp the film magazines when they are inserted through the openings in the housing and the magazines in the Film funding mechanism to pull;

2) to unlatch the magazine, to open it and to bring it to positions in which a sheet of unexposed film out of the magazine for the unexposed film and a sheet of exposed film in the magazine for exposed film can be promoted;

3) to convey the film sheets individually from the magazine for unexposed film to the vacuum-evacuable composite and to close the magazine after this conveyance has taken place;

H) exposed the magazines again to take up a film Open the film, remove the exposed film from the vacuum

609816/0986

to convey the evacuable composite into the magazine for exposed film and to close the magazines; and

5) open the door and eject the film magazines.

A feature of the invention is the use of infrared radiation directed at the film sheet portions which take their way along a film conveyor track. The reflected infrared radiation is used as an indication of the Presence of a film near the infrared sensor recorded. This sensing device has the advantage that the presence or absence of a film can be determined without physical contact with the Film takes place and without an undesired exposure of the film,

Another feature is the use of such infrared sensors to initiate the activity of certain components based on the scanned position of a film sheet. The use of limit switches as sensors to trigger the actuation of certain components is also described below described.

Likewise, a feature of the invention is the arrangement of a vacuum-evacuable composite, which in one area an L-shaped chamber is movably mounted, and a film conveyor system that is in a connecting chamber area is arranged in the vicinity of one end of the path of the film composite. The compact design, which obtained by this arrangement results in the smallest possible length of the film conveying path and the smallest possible mechanical effort required to move the film sheets

609816/0986

between the magazines and the vacuum-evacuable composite is required.

It is also a feature of the invention to use a film identification system which afterwards forms an identification image on a peripheral lip of each film sheet the greater part of the film foil has been brought into the light-tight environment of the vacuum-evacuable composite and after the film magazines have been closed to prevent exposure of other sheets of film.

The features according to the invention also include the designs the magazine for unexposed and exposed film, the vacuum-evacuable collar, the adjustment system, the film feed mechanism and the various components of the film feed mechanism all working together to form a compact, lightweight imaging device capable of capturing a rapid succession of X-ray images enables.

From the foregoing it follows that the main object underlying the invention is to provide a novel and to develop improved x-ray imaging devices.

As will be explained in more detail below, the film magazines 400, 450 introduced into the film conveying mechanism 500 at points shown in dashed lines in FIG. Before an unexposed Film sheet can be conveyed from the magazine 400 for unexposed film, and before an exposed film sheet can be fed into the magazine 450 for exposed film, the covers of the magazines 400, 450 must be opened and the magazines 400, 450 must be moved to the positions shown in solid lines in FIG. The following is an actuating mechanism 600 (not shown in FIG. 21) for opening and moving the magazines 400, 450 is described.

A conveyor roller system 800 is used to convey film foils to and from the magazines 400, 450. After the magazines 400, 450 have been moved into the positions shown in FIG. 21 with full lines, the conveying of a

609816/0986

- 34 - 254A848

Film film from the magazine 400 for unexposed film initiated by the fact that the carrier plate 4 35 in the magazine 400 for unexposed film is raised to the top sheet of unexposed film in support of a main feed roller 502 to bring. When the feed roller rotates, the top film is placed between the roller and a locking bar 501 inserted.

The film foil is then conveyed along a path which is indicated by arrows 503. The film conveyor is driven by large diameter rollers 504, 505, 506, rollers 507, 508, 509, 510, 511, fixed film guides 515, 516 and pinch rollers 512, 513 are determined. The pinch rollers 512, 513! Guide the film into the vacuum-evacuable composite 200. A film foil arranged in the vacuum-evacuable composite 200 is denoted by 201. This film sheet 201 has a "lip" 201A extending between the pinch rollers 512,513.

Before the composite 200 moves to bring the film sheet 201 to an exposure station, the lower Pinch roller 513 lowered as indicated by arrow 515 to reveal lip 201A of film sheet 200. The composite 200 then brings the film sheet 201 to an exposure station and returns the exposed film sheet, to bring the film lip 201A between the pinch rollers 512, 513.

The conveying of the exposed film sheet 201 from the vacuum-evacuable The composite 200 to the magazine 450 for exposed film is made by lifting the lower pinch roller 513 initiated.

Roller 519 and roller 505 to guide. The soft foam rubber roller 521 is placed on top of the open exposed film magazine 450 and guides the film sheet into the exposed film magazine 450.

The conveyance of the film sheets along the paths 503, 518 is monitored by a series of light-emitting diode and sensor units 530, 531, 532, 533, 534. Each of the diode units 530-533 has a light source which directs invisible infrared light radiation to the associated film web which it is monitoring. When a film sheet moves along the associated film path, the infrared light is reflected back onto a light-sensitive part of the diode unit. Upon receiving reflected light, the diode unit causes a change in an electrical signal indicating the presence of a film sheet adjacent the diode unit. Light emitting diode and sensing units of this type are commercially available from one
A number of companies are available, for example from Monsanto Company, St ₈ Louis, Mo. 63 166, which markets the diode sensor units under the model designation MCA-7.

As shown in Fig. 22, a similar arrangement is made up of a Actuator arm 877, link 876, and lever 874 on the opposite side of film feed mechanism 500 provided adjacent to the side plate 601. When the shaft 873 is rotated, the actuator arms 877 become common raised and lowered. The arms 877 are raised by an extension movement of the piston rod 871, the lowering the actuating arms 877 is done by a retraction movement of the piston rod 871,

The actuating arms 877 have dual functions when the

R09816 / 0986

Arms 877 are in their fully lowered position the slots 880 are engaged with the portions 86 5 of the bushings 854 of reduced diameter and move the lower conveyor roller 513 to a position in which the bushings 854 abut against the bottom of the slots 860. if when the arms 877 are in a position between their top and bottom positions, they are rearward protruding tabs 881 arranged so that they rest against the tabs 202a (Fig. 5) on the vacuum composite plate 202 are formed. When the actuator arms 877 are in their fully raised position, can the rearwardly protruding tabs 881 engage the tabs 202a and lift them to the vacuum-evacuable Open composite 200 in order to allow a film to enter or emerge.

As shown in Fig. 26, a reversing motor 900 is for the reversible Drive the various conveyor rollers described provided. The motor 900 has an output shaft 901, which carries a pulley 902. A belt 903 is wrapped around the pulley. The belt 9 03 also runs a freely rotatable pulley 904 carried by the side plate 602 and the pulleys 783, 810 and 824. As a result of this arrangement, the motor 900 can simultaneously drive the conveyor rollers 502, 504, 505, 506, 507, 508, 509, 510, 511, 519 and the pinch rollers 512, 513.

As shown in Fig. 26, the guide rails 515, 516 are curved metal plates that are inserted between the rollers 507, 508 and 510, 511 are arranged. The curved guide rails 515, 516 extend laterally between the side plates 601, 602 and are attached to the side plates 601, 602 at opposite ends.

809816/0986

As can be seen from FIGS. 22 and 26, the guide rail 520 is a curved metal plate which extends along its Underside is supported by a shaft 9 20. The wave

920 extends laterally between side panels 601, 602 and their opposite ends are through Side plates 601, 602 supported for rotation. At the end of shaft 920 adjacent side plate 601 is a lever

921 attached.

As FIG. 2 2 shows, a double-acting compressed air cylinder 925 is provided for pivoting the lever 921. The cylinder 9 25 has a housing, the upper end region of which can be pivoted on the side plate 601 by means of a pin 926 is attached. The cylinder 925 has an extendable piston rod 9 27. A bracket 9 28 is of the piston rod 927 carried. A pin 929 is for the articulated connection of the bracket 928 and the lever intended.

When the piston rod 9 27 is extended, the lever 921 pivots the guide rail 520 into the position shown in broken lines in FIG. 21 Drawn position for guiding a film film along the path 518 its way out of the area of the roller 509 takes to the adjacent roller 519 in order to convey them between the roller 519 and the roller 505. When the piston rod 92 7 is withdrawn, as shown in Fig. 22, the guide rail 520 is raised to one position pivoted, in which it does not affect the conveyance of the film along the path 503.

The conveyance of a film sheet from the unexposed magazine 400 along the path 503 only begins when the piston rod 92 7 of the cylinder s 925 is withdrawn to the guide rail 5 to pivot 20 into its upper position, in which it is out of the way, and only when the

609816/0988

Piston rod 871 of cylinder 870 is extended to raise the lower pinch roller 513 and the vacuum-evacuable Open composite 200.

When the film sheet, which is fed from the unexposed film magazine 400, leaves the magazine 400 and between of the barrier bar 501 and the conveyance roller 502, the diode 530 carried by the barrier bar 501 supplies a signal. This signal is used to pull back and close as described below the magazines 400, 450 to effect.

When the film fed to the vacuum evacuable assembly 200 moves past the light emitting diode 532 (Fig. 21), the latter causes a change in an electrical signal that a solenoid valve (not shown) is actuated, which supplies compressed air to the compressed air cylinder 870 (Fig. 26). The piston rod 871 of the cylinder 870 is then withdrawn, whereby the arms 877 are lowered to close the vacuum evacuable assembly and the lower To move pinch roller 513 down to a position in which the lip 201a of the film sheet 201 by the pinch rollers 512, 513 is released. After the pinch rollers 512, 513 have released their grip on the film sheet 201, can the vacuum-evacuable composite 200 to an exposure station are driven to expose the film sheet 201, as described.

XIII. The conveyance of an exposed film sheet.

After the film sheet 201 has been exposed, the vacuum-evacuable composite 200 leads the film sheet 201 to a Position back in which the lip 201a of the film sheet

6098 16/0986

extends between the separate pinch rollers 512, 513. When the light emitting diode 533 detects the return of the lip 201a, it becomes "exposed" Film "promotional signal is generated which is used to initiate the performance of several operations.

One of the work processes that are initiated by the aforementioned conveying signal is the extension of the piston rod 871 to raise the 877 actuator arms. When the arms 877 are raised, the lower pinch roller becomes 513 brought into contact with the lip 201a of the exposed film sheet 201 and becomes the vacuum-evacuable film composite 200 open. When the compound 200 is open, the motor 900 is actuated to drive the various conveyor rollers, so that the film sheet 201 is conveyed along the path 518.

Another operation initiated by the "exposed film" conveyance signal is the extension of the piston rod 9 27 in order to pivot the guide rail 520 into its lower position, which is shown in phantom in FIG. 21.

Also another process that is caused by the aforementioned The conveying signal is initiated is the pushing out of the magazines 400, 450. When pushing out the magazines takes place the same sequence takes place as described above. The lids of the two magazines 400, 450 are opened and the magazines 400, 450 are moved into the positions shown in FIG. 21 with full lines.

From the foregoing description of the magazine unlocking, opening and ejecting mechanism 600, it will be recalled

brought that the cylinders 625 and 720 serve to move the rails 617, 717 along the guide rods 621, to effect part of the sequence of operations for magazine unlocking, opening and ejection. The movement of the rails 617, 717 is also useful for performing other operations during the conveyance of the film sheets along the paths 503, 518 and these additional functions are subsequently carried out described.

As can be seen in FIGS. 24 and 27, the rail 717 carries two hooks 950. When the rail 717, seen in the cited figures, moved to the right, the hooks 950 are extended to a position in front of the conveyor roller 505. The task of the hooks 950 is the inevitable conveyance of the trailing edge of an exposed film sheet in the magazine 450 for exposed film. Therefore, as part of the magazine extension work sequence that s-tett finds, before a sheet of exposed film is conveyed out of the vacuum assembly 200, the hooks 950 through a Movement of rail 717 extended to the right.

The hooks 950 remain extended until the trailing edge of a sheet of exposed film is fed into the magazine 450 is moving past the diode 5 34. The diode 534 signals the cylinder 720, the hook 950 retract to pull the trailing edge of film into magazine 450.

XIV “The withdrawal of the magazine.

As already stated, the magazines 400, 450 are both withdrawn after a sheet of unexposed film has been taken out the magazine 400 for unexposed film has been brought out

S0981S / 098S

254 48 4

and after a sheet of exposed film is fed into the exposed film magazine 450. The withdrawal of the magazine is done by the cylinder 625 which moves the rail 617, seen in Fig. 24, to the left.
