Abstract
A security scanner includes a scanner configured to transmit a scanning beam toward a target and detect a returned beam. The security scanner also includes a processing circuit configured to receive a characteristic of the target to be scanned, determine an allowable dosage based on the characteristic, adjust a parameter of the scanning beam based on the allowable dosage, and cause the parameter to be used in the scanning of the target.
Claims20
A security scanner, comprising:
- a scanner configured to transmit a scanning beam toward a target and detect a returned beam;
- and
- a processing circuit coupled to the scanner with a communication link and configured to:
- receive a characteristic of the target to be scanned from the scanner;
- determine a maximum allowable dosage based on the characteristic, a previous dosage, and a maximum dose exposure limit for the target to be scanned;
- adjust a parameter of the scanning beam based on the maximum allowable dosage;
- and
- cause the parameter to be used in the scanning of the target.
A security scanner for reducing a risk that a person may receive an inappropriate dose, comprising:
- a housing;
- a measurement device configured to determine a characteristic of the person and produce a characteristic signal;
- a processing circuit configured to:
- receive the characteristic signal;
- determine a maximum allowable dosage based on the characteristic signal, a previous dosage, and a maximum dose exposure limit for the person;
- and
- produce a beam signal based on the maximum allowable dosage;
- and
- a scanner coupled to the processing circuit and configured to direct a scanning beam toward the person that corresponds to the beam signal.
