Abstract
Abstract The dosimetry system used with a strontium-rubidium infusion system is a very high speed circuit capable of measuring the radioactive dosage infused into a patient in real time. The dosimetry system is capable of receiving very short duration input pulses generated by a photomultiplier tube in response to the presence of radioactivity.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
70 words
A strontium-rubidium infusion system comprising: (a) means for generating rubidium 82 in a solution which can be infused into a patient; (b) means for infusing said solution into a patient; (c) means for measuring the radioactivity present in said solution as it is infused into said patient; and (d) means for controlling said means for infusing in response to the amount of radioactivity which has been infused into said patient.
Claim 2
Dependent Claim
70 words
A strontium-rubidium infusion system comprising: (a) means for generating rubidium 82 in a solution which can be infused into a patient; (b) means for infusing said solution into a patient; (c) means for measuring the radioactivity present in said solution as it is infused into said patient; and (d) means for controlling said means for infusing in response to the amount of radioactivity which has been infused into said patient.
Claim 3
Dependent Claim
28 words
The strontium-rubidium infusion system of claim 1 wherein said means for generating rubidium 82 in a solution which can be infused into a patient comprises a strontium-rubidium generator.
Claim 4
Dependent Claim
24 words
The strontium-rubidium infusion system of claim 2 wherein said means for infusing said solution into a patient comprises a syringe including a plunger therein.
Claim 5
Dependent Claim
34 words
The strontium-rubidium infusion system of claim 3 wherein said means for infusing said solution into a patient further comprises means for electromechanically operating said syringe and means for moving the plunger of said syringe.
Claim 6
Dependent Claim
30 words

Claim 7
Dependent Claim
20 words
The strontium-rubidium infusion system of claim 5 further comprising electronic means for controlling said means for electromechanically operating said syringe.
Claim 8
Dependent Claim
29 words
The strontium-rubidium infusion system of claim 6 wherein said means for measuring the radioactivity present in said solution as it is infused into said patient comprises a dosimetry system.
Claim 9
Dependent Claim
21 words
The strontium-rubidium infusion system of claim 7 wherein said dosimetry system is connected to means for controlling said means for infusing.
