1. Röntgenavbildningsapparat för tänder med panoramavisning, som omfattar: 5. en röntgensträlavsändare (2) för att emittera röntgensträlar mot ett föremäl (1 ); medel (3) för att detektera en bild av röntgensträlar som har penetrerat föremälet; medel (4) för att rotera röntgenstralavsändaren (2) och detekte-10 ringsmedlen (3) av röntgensträlar integralt kring föremälet; medel (5) för att lagra bildinformation som kommer frän detekte-ringsmedlen (3) av röntgensträlar under funktion av vridmedel (4); och medel (6) för att behandla bildinformation för att bilda en tomo-15 grafisk tomografibild som följer en önskad tomografinivä pä ba- sen av bildinformation som har lagrats i lagringsmedlen (5) för bildinformation, samt för att utföra en beräkningsprocess för tomografibild, varvid behandlingsmedlen (6) för bildinformation hämtar rambilder frän lag-20 ringsmedlen (5) för bildinformation, och en föreningsprocess utförs för de hämtade rambilderna samtidigt när deras position förflyttas enligt ett valt för-flyttningsavständ i breddriktning av en spaltbild som i sin form motsvarar röntgenspaltsträlar, kännetecknad av, att flera tomografibilder beräknas, vilka omfattar en tomografibild av en bestämd tomografinivä och en tomogra-25 fibild av en annan tomografinivä, och vilka motsvarar flera i avsändnings-riktningen av röntgensträlar efter varandra anordnade tomografiniväer, vilka omfattar sagda bestämda tomografinivä och andra tomografinivä, och mellan dessa flera tomografibilder utförs. en konvolutionsprocess eller en frekvens-process för bildens densitet, vilken frekvensprocess använder Fourier-trans-30 form, varvid störningar kan avlägsnas frän den sagda bestämda tomografi-bilden.
2. Röntgenavbildningsapparat för tänder med panoramavisning enligt patentkrav 1, kännetecknad av, att frän tvä eller flera tomografibilder 35 avlägsnas störningarna och tomografibilderna, frän vilka störningarna har avlägsnats, förenas med varandra, varvid man fären förenad tomografibild.
