Abstract
Abstract In an illustrative embodiment, body zone selector keys are associated with a visual representation of the human body. When a body zone key is actuated, the available exposure programs for specific organs or body portions in the selected body zone are displayed on respective indicator panels having respective adjacent operating keys. For the case of seven zone keys and seven operating keys, an electronic fixed value store (e.g. a PROM) may contain seven sets of storage locations, each set containing data for controlling the alphanumeric displays at the seven indicator panels to indicate available exposure programs related to one body zone. For example, there may be twelve matrices formed of LEDs in each indicator panel for display of twelve alphanumeric characters to designate the organs or body portions indicative of the seven different exposure programs currently available for selection.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
310 words
An x-ray diagnostic apparatus having operating keys for the organwise programmed setting of the exposure data, having an indicator field respectively assigned to each operating key for indicating respective body portions or body organs, and having an indicator board associated with the operating keys and including a representation of the body zones of a human body, and also means comprising a selective switching device for selecting a respective one of a specific number of body zones and for assigning a set of body portions or body organs for indication on the indicator fields according to the selected body zone, the selective switching device and the operating keys cooperating to determine the exposure data in conformity with the selected specific body part or body organ of the set corresponding to the selected specific body zone, and indicator means controlled by the selective switching device for producing at the indicator fields assigned to the respective operating keys a set of displays representing the respective body parts or body organs of the set corresponding to the selected body zone, characterized in that an electronic fixed value store (26) is present for controlling the indicator means (22), said store having a specific number of store locations corresponding to each setting of the selective switching device (15 through 21), said fixed value store being responsive to the setting of the selective switching device (15 through 21) such that said store respectively supplies a respective output signal which characterizes the respective set of displays representing body portions or body organs which correspond with the respectively selected body zone, and the indicator means (22) comprising an electronic luminous display for alphanumeric character reproduction, said luminous display being controlled by the output signal of the electronic fixed value store (26) to provide a set of alphanumeric displays at the indicator fields in accordance with the selected body zone.
Claim 2
Dependent Claim

An x-ray diagnostic apparatus having operating keys for the organwise programmed setting of the exposure data, having an indicator field respectively assigned to each operating key for indicating respective body portions or body organs, and having an indicator board associated with the operating keys and including a representation of the body zones of a human body, and also means comprising a selective switching device for selecting a respective one of a specific number of body zones and for assigning a set of body portions or body organs for indication on the indicator fields according to the selected body zone, the selective switching device and the operating keys cooperating to determine the exposure data in conformity with the selected specific body part or body organ of the set corresponding to the selected specific body zone, and indicator means controlled by the selective switching device for producing at the indicator fields assigned to the respective operating keys a set of displays representing the respective body parts or body organs of the set corresponding to the selected body zone, characterized in that an electronic fixed value store (26) is present for controlling the indicator means (22), said store having a specific number of store locations corresponding to each setting of the selective switching device (15 through 21), said fixed value store being responsive to the setting of the selective switching device (15 through 21) such that said store respectively supplies a respective output signal which characterizes the respective set of displays representing body portions or body organs which correspond with the respectively selected body zone, and the indicator means (22) comprising an electronic luminous display for alphanumeric character reproduction, said luminous display being controlled by the output signal of the electronic fixed value store (26) to provide a set of alphanumeric displays at the indicator fields in accordance with the selected body zone.
Claim 3
Dependent Claim
53 words
An x-ray diagnostic apparatus according to claim 1, characterized in that setting means comprising a programmable read only memory (51) is operable for establishing the exposure data, said programmable read only memory being jointly responsive to the setting of the operating keys (1 through 7) and the selective switching device (15 through 21).
Claim 4
Dependent Claim
36 words
An x-ray diagnostic apparatus according to claim 1, characterized in that the selective switching device (15 through 21) is formed by keys which are arranged in the body zones as represented on the indicator board (13).
Claim 5
Dependent Claim
100 words
An x-ray diagnostic apparatus according to claim 1, characterized in that setting means comprising a programmable read only memory (51) is operable for establishing a number of exposure data programs corresponding to the number of combinations of settings of the operating keys (1 through 7) and the selective switching device (15 through 21), said setting means having means responsive to the settings of the operating keys to produce a binary output signal for representing a desired exposure data program, and the programmable read only memory being responsive to the binary output signal to supply exposure setting signals in accordance therewith.
Claim 6
Dependent Claim
36 words
An x-ray diagnostic apparatus according to claim 4 characterized in that the selective switching device (15 through 21) is formed by keys which are arranged in the body zones as represented on the indicator board (13).
