Flexible Film Cassettes लचीला फिल्म कैसेट

Flexible/Single Envelope Cassettes are of a similar design. They are single envelope, open at one end for loading and unloading film/screens. The open end is held closed and light sealed by means of ‘VELCRO’ nylon fastener. There is an extra finger tab at the sealed end to assist in holding the cassette to the bench for easier and quicker unloading. Closure is normally made of the shorter side of a rectangular cassette but ‘specials’, with the opening on the long side, can be supplied to order. लचीला / एकल लिफाफा कैसेट एक समान डिजाइन के हैं। वे एकल लिफ़ाफ़ हैं, फिल्म / स्क्रीन लोड करने और उतारने के लिए एक छोर पर खुले हैं। खुले अंत को बंद किया जाता है और ‘वीएलसीआरओ’ नायलॉन फास्टनर के माध्यम से बंद कर दिया जाता है। आसान और तेज उतारने के लिए बेंच में कैसेट को पकड़ने में सहायता करने के लिए मुहरबंद अंत में एक अतिरिक्त उंगली टैब है। आम तौर पर एक आयताकार कैसेट के छोटे पक्ष से बंद होता है, लेकिन ‘विशेष’, लंबे समय तक खोलने के साथ, आदेश को आपूर्ति की जा सकती है।

Standard Single Envelope Cassettes are made from 400 micron black PVC. Over the years these have become the standard cassette for industry not recommended for use in very cold weather.

Reinforced Single Envelope Cassettes are made from thin, yet strong PVC/Nylon/PVC laminated material. the Nylon reinforcement is in the form of a mesh and reduces the tendency of the PVC to split at the seams after much use.The PVC laminate retains its flexibility in cold climates and is more suitable for use at low temperatures.

One Seam Reinforced Single Envelope Cassettes are made to outlast any other flexible type of cassette. Constructed without side seams from rugged Nylon reinforced PVC, with one joint at the back of the cassette, overcoming the weakness and tendency to split experienced with other single envelope cassettes that are welded along the sides. Made from specially formulated, heavy duty, Nylon reinforced PVC coloured Black on the inside and Yellow on the outside for easy recognition.

Double Envelope Cassettes consist of two plain, black envelopes without any means of closure. Film and screens are loaded into the inner envelope, the smaller of the two. This is then inserted, open end first, into the larger, outer envelope. light tightness is assured because the open end of the inner envelope is up against the closed end of outer. They are made from standard 400 micron PVC material and are clearly marked on the inner and outer envelopes for easy identification in the darkroom or on site.

Special Cassettes can be supplied to customers own requirements.
Single Envelope up to 3 metres long for pipeline work.

Lead Intensifying Screens

Lead Intensifying Screens are thin sheets of lead foil mounted on card for ease of handling. One is placed either side of x-ray film and in close contact with it, inside the cassette or film holder prior to exposure. They are used in most radiographic techniques, excluding some of those employing low kilo-voltages, because they reduce the exposure required and improve the quality of the image. The screens are made from the finest available radiographic lead foil, laminated onto flexible white photographic base card. The lead surface is not covered with a lacquer coating. The specially formulated lead-rich alloy is hard enough not to cause the transfer of deposits onto the film in normal use. Un-coated lead also has the advantages of higher intensification and the absence of problems associated with uneven coating or melting or partial wearing away of the lacquer. The corners of the screens are rounded to a convenient radius to prevent damage to films and cassettes. Each screen is clearly stamped with the lead thickness.To ensure that the screens are received in perfect condition, the lead surface is protected by a PEEL-OFF protective plastic film. IT IS ESSENTIAL that the protective film is removed before using the screens.The film is best removed by applying a piece of adhesive tape to the corner of the screen, the tape and film will peel away together cleanly and easily.

Intensifying screens are made in sizes for all the world markets. Standard metric and imperial sizes are cut according to BS3490:1985 and ISO 5655-1982. Special sizes can be made to order. The following lead thicknesses (mm.) are available; 0.050, 0.100, 0.125, 0.150, 0.200, 0.250, 0.500, 0.750, 1.000, 1.500, 2.000 and 3.000. Pairs of any thickness combinations can be supplied. Screens are normally sold in 5, 10 or 25 pair packs, but those thicker than 0.250mm are available only in single pair packs.

Intermediate (centre) screens, with lead foil on each side of the card support, are available with any lead thickness. Most commonly they are supplied as 0.10mm (0.05 lead on each side) or 0.20mm (0.10mm of lead on each side)

IQI EN 462-1 / ISO 19232

EN 462-1:1994-ISO 19232 Wire Type were introduced as a EUROPEAN STANDARD to supersede the German Standards Institute (DIN 54.109) and the British Standards Institute (BS3971:1980 type 1) Image Quality Indicators. Each indicator consists of a series of seven parallel wires of different thickness mounted and encapsulated between two thin sheets of transparent, flexible PVC. A lead monogram indicates the number of the thickest wire, the material and the EN symbol.

Wire lengths ; 10mm, 25mm or 50mm (Please state length required when ordering)
Indicator Sizes:
There are four sizes of EN-ISO Image Quality Indicators.
Size 1 – contains wire numbers 1 to 7 and used for material thicknesses in the range of 40 to 160mm
Size 6 – contains wire numbers 6 to 12 and used for material thicknesses in the range of 12.5 to 50mm
Size 10 – contains wire numbers 10 to 16 and used for material thicknesses in the range of 5 to 20mm
Size 13 – contains wire numbers 13 to 19 and used for material thicknesses in the range 2.5 to 10mm

All sizes are available in Steel (Fe), Aluminium (Al), and Copper (Cu) Titanium (Ti) Image Quality Indicators are only available in sizes 10 and 13.
As an illustration the identification (i.e. lead monogram) for, say Size 1 (Wire numbers 1 to 7) in carbon steel (Fe) would be 1 FE EN
All EN-ISO Image Quality Indicators are individually numbered and supplied with a Certificate of Conformity

Image Quality Indicator EN 462-2

This European standard replaces the previous national standards such as NFA 09 – 205 (AFNOR) or BS 3971. They are manufactured in Carbon Steel as standard and can also be manufactured in Aluminium, Copper, Titanium to order.

There is a direct correlation between the specified EN models and the previous AFNOR types:

AFNOR Model    H3   HA   HB    C
EN Model            H1   H5   H9   H13

Description. The EN 462-2 IQIs compriseof six plaques, measuring 5 x 7mm, 7 x 10mm or 15 x 15mm, which are encapsulated in transparent plastic along with an identification monogram in cast white metal. Each plaque has one or two through-drilled holes whose diameter is the same as the plaque thickness. The IQIs are supplied in a wallet with a Declaration of Conformity.

Quality Assurance. Manufacturing, including inspection, follows a written procedure, which forms part of a Quality Management System registered according to ISO 9001. Each IQI carries a unique serial number. The Declaration of Conformity provides a complete manufacturing history.

The monogram within the IQI identifies the model, for example, H 13 FE means:
H = Hole type IQI, 13 = Number of the thinnest step, FE= Steel.

H1 Stepwedge Range 0.125 to 4mm  Material Thickness 6.3 to 20mm

H5 Stepwedge Range 0.32 to 1mm material Thickness 16 to 50mm

H9 Stepwedge Range 0.8 to 2.5mm material Thickness 40 to 125mm

H13 Stepwedge Range 2 to 6.3mm Material Thickness 100 to 315mm

Duplex IQI EN462-5

Duplex IQI

The Duplex IQI is used in many X-ray applications, especially in digital X-ray. Designed for evaluating total image unsharpness of film and additionally basic spatial resolution of digital images according to EN 13068 (Radioscopy), EN 14784 and ISO 13671

CR – Computed Radiography with imaging plates), ISO 17636-2 (digital radiology of welds – flat panel detectors) or ASTM E 2597 (characterization of digital detector arrays). A new ISO standard is in preparation, describing the possibility of using the Duplex IQI for determination of focal spot size of X-ray tubes.

Image valuation with Duplex Wire Type IQI

In radiography the wire pair with largest diameter d has to be identified, which cannot be separated visually.

The radiographic film may be magnified up to 4X.

In digital radiology the separation between wires (Dip) is evaluated. The wire pair with largest d, showing Dip less than 20 percent of the wire pair contrast, identifies total image unsharpness (U = 2d) and basic spatial resolution (SRb = d) of digital image.
