Regarding claim 5, KOCH discloses claim 1. But KOCH fails to disclose a boron concentration measurement room that is independent of other rooms and that is used to measure a boron concentration of a therapy target object . SOMMER, however, discloses a measurement room (imaging rooms 7’s with 9) that is independent of other rooms (2, 8, other 7) and that is used to measure Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA applications) to combine/modify the invention of KOCH, with a measurement room that is independent of other rooms, as taught by SOMMER, to use for x-ray imaging the portion of the patient to be treated via the therapy beam for increased accuracy and prevention of unnecessary healthy tissue irradiation and increased high patient throughput (pg. 6). But KOCH as modified by SOMMER fails to disclose a boron concentration measurement room that is used to measure a boron concentration of a therapy target object. (JP 6538423 B2)., however, discloses an irradiation room (fig. 1, containing 12, 18 and 20) that is a boron concentration measurement room (fig. 1; containing 10, 20) that is used to measure (via 19, 20) a boron concentration of a therapy target object (on 18). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA applications) to combine/modify the invention of KOCH, with an irradiation room that is a boron concentration measurement room that is used to measure a boron concentration of a therapy target object, as taught by (JP 6538423 B2)., to use as a substitution of one known irradiation/treatment room type (i.e. boron centration measuring and irradiation treatment room) for another (i.e. generic beam therapy/imaging room) to obtain predictable boron concentration measurement and tumor treatment results. 2. Claim(s) 9 is/are rejected under 35 U.S.C. 103(a) as being unpatentable over KOCH (DE 102006057626 B3) in view of LIFSHITZ et al. (US 20090154645 A1).
