The invention relates to a device (1) for writing on thermographic material (5). The inventive device (1) comprises a heater (20) with which the thermographic material (5) is preheated to a temperature, which is lower than a writing temperature. The thermographic material (5) can be written on with a writing instrument (10) which is distanced from the thermographic material (5) after input of an information signal (s(t)). The writing instrument (10) has a plurality of individually controllable point sources (30-33; 51-53). The thermographic material (5) can be written on in a point-by-point manner with said point sources (30-33; 51-53).

A recording process comprising the steps of: information-wise exposing to radiation a photosensitive thermally developable photographic material, thereby producing a latent image; and heating the photosensitive thermally developable photographic material, characterized in that the photosensitive thermally developable photographic material is on one and the same holding or guiding means during both the information-wise exposure step and the heating step; and the information-wise exposure step is carried out during the heating step; and a method of increasing the photosensitivity of a photosensitive thermally developable photographic material.

The invention relates to a device (10,60) for reading out information stored in a phosphor carrier (15) and to an X-ray cassette (70) which contains the phosphor carrier (15) and such a device. The inventive device (10,60) has a radiation source (11;20, . . . ,29,30 . . . 39; 50,53;61) that can emit a first radiation source (16) with which the phosphor carrier (15) can be exited such that the carrier emits a second radiation (17). This second radiation (17) comprises an image of the information stored in the phosphor carrier (15). The device (10,60) additionally has a receiving means (12,62) which contains a number of point elements (PD1, . . . PDn) in order to receive the second radiation (17) emitted from the phosphor carrier (15) in a point-by-point manner. The second radiation of a point of the phosphor carrier (15) can thus be received by each one of the point elements (PD1, . . . ,PDn).
摘要:
A cassette for an x-ray film coated with a stimulable phosphor layer is formed so that a cassette memory which carries storable, recordable, readable and erasable data is rigidly attached to the cassette at the positioned spaced a predetermined distance from a given cassette corner. This position is the same for all cassettes of the same type and different formats.

A method and to a corresponding apparatus for processing information carriers, in particular for reading out storage phosphor plates (2) for storing X-ray information, an information carrier (2) and/or a container (1) in which the information carrier (2) is located being processed, in particular being moved and/or fixed, by at least one mechanical processor (13), the processor (7) being driven by at least one stepper motor (10), and information from the information carrier (2) being read out and/or written in the information carrier. In order to simplify the processing of information carriers (2) with at the same time high precision when determining the position of the processor (13) and reduced production costs, provision is made such that a motor load is recorded which is a measure for the load of the stepper motor (10) while the processor is being driven, and information about the position of the processor (13) is deduced from the number of steps, which corresponds to the number of steps of the stepper motor (10) while the processor (13) is being driven, taking into account the motor load recorded.

摘要:
A stack of individual sheets of film is enclosed by lightproof plastic packaging. An opaque sheet is disposed at the bottom of the stack, and the side of the opaque sheet confronting the packaging is provided with a bar code containing information about the film. The packaging is removed in a lighttight area of a processing unit for the film and the bar code is read. The opaque sheet prevents the radiation used to read the bar code from reaching the film. The information retrieved from the bar code is employed to control processing of the film.
