Abstract

A collimator storage device for a collimator having a certain diameter. The device comprises a support, a first collimator storage member having a first slot for inserting the collimator, and a second collimator storage member having a second slot for inserting the collimator. The first and second collimator storage members are mounted at the support in a distance from each other which is smaller than the diameter of a collimator having smallest size such that the first and second slots combine for bearing a smallest size collimator or a collimator having larger diameter therebetween.

Claims

1. A collimator storage device, comprising:

(a) a support comprising a support frame having first, second, third and fourth lateral frame surfaces, a top surface and a bottom surface, all said surfaces defining a support frame cavity;

(b) a first collimator storage member mounted at the support frame outside the support frame cavity and shaped like a comb having a row of comb teeth and comb gaps between adjacent comb teeth, said comb gaps forming a number of first vertical slots corresponding to the number of collimators;

(c) a second collimator storage member mounted at the support frame outside the support frame cavity and shaped like a comb having a row of comb teeth and comb gaps between adjacent comb teeth, said comb gaps forming a number of second vertical slots corresponding to the number of collimators; and

(d) a number of collimators each having at least a predetermined minimum diameter;

wherein always one first vertical slot of the number of first vertical slots together with one second vertical slot of the number of second vertical slots forms a pair of slots, wherein said first and second storage members carry at least one collimator out of said number of collimators, said collimator being received in a vertical position by the first and second vertical slots of one of said pair of slots, said first and second vertical slots being separated by a distance which is less than the predetermined minimum diameter of the collimator received by them.

2. The device according to claim 1, for a first and a second number of collimators, comprising a first pair of first and second collimator storage members having each a number of slots corresponding to the first number of collimators, and a second pair of first and second collimator storage members having each a number of slots corresponding to the second number of collimators.

3. The device according to claim 1, further comprising a third collimator storage means which is mounted at the support perpendicular with respect to the first and second collimator storage members for storing a collimator in horizontal position.

4. The device according to claim 1, wherein the first and second collimator storage members lie on a common horizontal line.

5. The device according to claim 3, comprising collimators having heavier weights and collimators having lighter weights, wherein the first and second collimator storage members are designated for storing the lighter collimators and the third collimator storage means is designated for storing the heavier collimators.

6. The device according to claim 3, wherein the third collimator storage means comprises a first and second storage tray for storing a first and second collimators in horizontal positions.

7. The device according to claim 3, further comprising a first and second bumpers mounted at the support underneath the third collimator storage means for restricting the relative linear movement between a detector head deposited underneath the third collimator storage means and the support.

8. The device according to claim 2, wherein the first pair of first and second collimator storage members is mounted perpendicularly with respect to the first lateral frame surface and the second pair of first and second collimator storage members is mounted perpendicularly with respect to the second lateral frame surface.

9. A collimator storage device comprising:

(a) a support comprising a support frame having first, second, third and fourth lateral frame surfaces, a top surface and a bottom surface, all said surfaces defining a support frame cavity;

(b) a first collimator storage member mounted at the support frame outside the support frame cavity and having at least one first vertical slot for inserting a collimator;

(c) a second collimator storage member mounted at the support frame outside the support frame cavity and having at least one second vertical slot for inserting a collimator; and

(d) at least one collimator having at least a predetermined minimum diameter;

wherein the first and second vertical slots are separated by a distance which is less than the predetermined minimum diameter and the collimator is received in the first and second vertical slots and carried by the first and second collimator storage members in a vertical position.

10. The device according to claim 9, for a number of collimators each having at least a predetermined minimum diameter, wherein the first collimator storage member has a number of first vertical slots and the second collimator storage member has a number of second vertical slots, wherein always one first vertical slot of the number of the first vertical slots together with a second vertical slot of the number of second vertical slots forms a pair of slots, the first and second vertical slots of each pair of slots being separated by a distance which is less than one of the predetermined minimum diameters, and wherein the first and second collimator storage means carry at least one collimator out of the number of collimators, said collimator being received in a vertical position by the first and second vertical slots of one of the pairs of slots, said first and second vertical slots being separated by a distance which is less than the predetermined minimum diameter of the collimator received by them.
