1. A method for producing a sensor unit having a support plate, a stack of collimator sheets being attached on an inner side of the support plate, the method comprising:producing a plurality of scintillator strips, each of the plurality of scintillator strips being produced from a plurality of scintillator pixels adjoining one another along one dimension;forming a plurality of sensor strips, each of the plurality of sensor strips being respectively formed by a longitudinal side of one scintillator strip being connected to a respective one photodiode strip made of a plurality of photodiodes, adjoining one another along one dimension such that, for readout purposes, respectively one of the plurality of photodiodes is respectively associated with one of the plurality of scintillator pixels; andindividually mounting a plurality of the formed sensor strips on an outer side of the support plate, facing away from the stack of collimator sheets, wherein a narrow side provided for contacting the photodiodes of each of the photodiode strips respectively protrudes beyond the adjacent scintillator strip or strips. 2. The method as claimed in claim 1, wherein the sensor strips are, during the assembly on the support plate, respectively aligned with a stop which is fixed with respect to the collimator sheets. 3. The method as claimed in claim 2, wherein the sensor strips are aligned with a stop formed by the collimator sheets. 4. The method as claimed in claim 1, wherein, during the assembly of the sensor strips on the support plate, the photodiode strips are respectively aligned substantially perpendicularly with respect to the support plate. 5. The method as claimed in claim 4, wherein, during the assembly of the sensor strips on the support plate, the photodiode strips are respectively arranged substantially flush with the collimator sheets. 6. The method as claimed in claim 1, wherein, during the assembly on the support plate, interspaces formed between the individual sensor strips are subsequently filled. 7. The method as claimed in claim 1, wherein the photodiode strip is adhesively bonded to the scintillator strip using an optically transparent adhesive in order to produce the sensor strip. 8. The method as claimed in claim 1, wherein the individual scintillator pixels are produced in a substantially cuboid shape. 9. The method as claimed in claim 1, wherein individual beams of scintillator material are initially lined up parallel to and at a certain distance from one another in order to produce the scintillator strips, wherein the beams are subsequently connected by filling septa with at least one of a light reflecting and absorbing material and wherein this combination is finally separated out into the individual scintillator strips in the transverse direction of the individual beams. 10. The method as claimed in claim 1, wherein the five sides of each scintillator pixel not intended to adjoin a photodiode are provided with a reflector lacquer before the sensor strip is produced. 11. A sensor unit, comprising:a support plate;a stack of collimator sheets attached to the support plate;a plurality of sensor strips attached to the support plate, each of the plurality of sensor strips being respectively formed by a scintillator strip and a photodiode strip, and each of the plurality of sensor strips being individually attached to the support plate, wherein a narrow side provided for contacting the photodiodes of each of the photodiode strips respectively protrudes beyond the adjacent scintillator strip or strips. 12. The sensor unit as claimed in claim 11, wherein each of the plurality of sensor strips are attached to the support plate such that the photodiode strips are respectively arranged substantially perpendicularly to the support plate, wherein each of the plurality of photodiode strips are each basically arranged between two scintillator strips. 13. The sensor unit as claimed in claim 12, wherein the photodiode strips are arranged such that the photodiode strips are substantially flush with the collimator sheets. 14. The method as claimed in claim 2, wherein, during the assembly of the sensor strips on the support plate, the photodiode strips are respectively aligned substantially perpendicularly with respect to the support plate. 15. The method as claimed in claim 3, wherein, during the assembly of the sensor strips on the support plate, the photodiode strips are respectively aligned substantially perpendicularly with respect to the support plate. 16. The method as claimed in claim 6, wherein, during the assembly on the support plate, interspaces formed between the individual sensor strips are subsequently filled using a casting resin. 17. The method as claimed in claim 9, wherein the beams are subsequently connected by filling the septa with a polymer which is liquid at first. 18. The sensor unit as claimed in claim 11, wherein the sensor strips include a single row of scintillator pixels attached to a single row of photodiodes.
