- the pre-setting stress on the patient is reduced, and since the overall time per examination is also reduced, patient throughput can be increased.
- a patient positioning device in a medical panorama X-ray photographing apparatus in which after data of the relative position of the subject to the X-ray photographing apparatus supplied from a sensor is compared with data of the relative position of a tomographic zone to the X-ray photographing apparatus thus to produce compa ⁇ son data which is in turn transmitted to a d ⁇ ve circuit, a tomograph forming assembly and/or the subject is moved from coinciding with each other
- the device further includes a compa ⁇ ng a ⁇ thmetic circuit in which the detected position data of the subject and position data of the tomographic zone are a ⁇ thmetically compared in order to improve operatabi ty and positioning accuracy
- the device furthermore includes a sensor, which is adjustable for angular and vertical setting with the use of sensing position changing means in order to improve adaptability to individualities of the subject.
- What is needed is an arrangement that allows an x-ray imaging apparatus, specially an apparatus for mammographic examination, to automatically assume settings specific for a certain person to be examined.
- Advantages with the arrangement according to the present invention are that the burden on the operator and the patient reduces and the number of persons which can be examined and the examination flow increase as the pre-adjustment time reduces.
- the initially mentioned arrangement further comp ⁇ ses a device for adjusting collimator slots widths based on information ret ⁇ eved from said database and/or a position of said pedals Moreover, the arrangement comp ⁇ ses means to detect the positions of said pedals, a compression sensor for sensing a pressure exerted by said pedals onto said breast and adjusting said pressure and position sensors for positioning said x-ray source
- the identity input device is any one of a card reading device, a fmger p ⁇ nt sensor, a pin-code input device or a keyboard
- the invention also relates to a method in initially mentioned arrangement, which is characte ⁇ sed by the steps of claiming an identity of said patient, upon receiving said identity ret ⁇ eving a set of setting data from at least one last x-ray examination of said person and/or a position of said pedals, and adjusting collimator slots' widths based on said information
- a substantially manual adjustment is earned out and results of said substantially manual adjustment are registered for later examinations
- Fig 1 is a schematic diagram illustrating an x-ray imaging according to the present invention
- Fig 1 is a schematic diagram of a system employing an arrangement according to the invention, specially for mammography examming apparatus
- the essential parts of the system 10 comp ⁇ se a radiation source 11, collimator means 12 and a pedal pares, including first and second compression pedals 13a and 13b, respectively
- the female breast 14 is positioned between the compression pedals 13a and 13b
- the upper compression pedal 13a is at least partly transparent to the x-ray radiation while lower pedal 13b can contain a film or a detector assembly (not shown).
- the arrangement according to the invention mamly comp ⁇ ses a main control unit 15 and connected to it sub-control units 16-19.
- the sub-control unit 16 is an x-ray source controller and for instance controls the x-ray intensity by controlling power level to the tube and the current between the cathode and anode of the x-ray tube
- the sub-controller 17 is a step motor or the like for relocating the x-ray source 11 ho ⁇ zontal and/or vertical directions with respect to the breast's 14 position.
- the sub-controller denoted 18 adjusts the collimator 12 features, e.g the width of the collimator slots.
- the sub-controller 19 is a device, such as a step motor which displaces the pedals 13a, 13b relative each other and controls the pressure exerted onto the breast 14. It is also possible to move the entire apparatus including the x-ray source and the pedals 13a/13b vertically to adopt it to the patient's height.
- collimator slit's width can be adjusted with regard to the patient data and/or the compressed breast thickness (distance between the pedals) to adjust the radiation dose. Hence, there is no need to adjust the slits' widths (in multi slits colhmators) under the examining.
- the main control unit 15 also includes or communicates with an input device 20 and a data storage unit (database) 21.
- the function of the control unit includes controlling the sub-control units based on the input from the input device and the storage unit.

- the invention is most suitable for recurrent x-ray examinations, e.g mammographic examinations and specially for mass screening situations, as the settings of the system are depending on the patient's physical appearance, such as length, breast thickness etc.
- the invention may also be used for bone densitometry examination. Following non limiting example simplifies the underrating of the invention:
- the height of the pedals 13a, 13b, and the x-ray source is adjusted in a known way with respect to the height of the patient and the breast of the person is placed in between the compression pedals 13a, 13b exercising an amount of pressure on the breast.
- the height of the pedals and the source are registered automatically by means of sensors ( or manually) and stored in a database 21 with relation to the patient identity.
- the intensity, and exposure area and time of the x-ray beam is adjusted by adjusting the power and the current to the tube and possibly by adjusting the collimator 12. All settings are stored in the above-mentioned database for later use Sensors are provided for reading the setting values, however, a manual reading and data ente ⁇ ng may occur
- the system is activated by ente ⁇ ng her identity through the input device 20, which can be an identity number, a social secu ⁇ ty number, a f ger p ⁇ nt or any other unique identifying code.
- the main control unit Based on the identity of the person to be examined, and preferably after an identity check, the main control unit ret ⁇ eves the height, pedal pressure, x-ray intensity, focussing and exposure time and other relevant data from the database 21.
- the mam control unit controls the sub-control units 16-19 with respect to the data ret ⁇ eved from the database
- the step motor 17 positions the x-ray source 11 in a correct height
- the pedals 13a and 13b are brought into correct height and the operator helps placing the breast of the patient between the pedals, which then brought together by the step motor 19 to compress the breast into a substantially flat body for best contrast.
- the x-ray source is controlled based on the breast thickness to radiate with correct power. If there is a need for readjustment of the settings, the new settings are stored.
