Abstract
In a method and apparatus for determining at least one patient-specific safety parameter for a medical imaging examination conducted on the patient by a medical imaging device, position data of the patient are acquired by a position data detector while the patient is on a patient-positioning device of the medical imaging apparatus. The acquired position data are evaluated in a processor in order to determine position information of the patient. The patient-specific safety parameter is determined using the position information of the patient.
Claims16
A method for determining at least one patient-specific safety parameter for a medical imaging examination conducted on a patient by a medical imaging apparatus, said method comprising:
- with a position data acquisition detector, acquiring position data of the patient while the patient is situated on a patient-positioning device of the medical imaging apparatus;
- transmitting the acquired position data to a safety parameter determining processor;
- in said safety parameter determining processor, evaluating the acquired position data to obtain position information of the patient;
- in said safety parameter determining processor, generating a patient model based on said position information of the patient, the patient model being an Active Shape Model;
- and
- in said safety parameter determining processor, determining a patient-specific safety parameter using the patient model, and making the patient-specific safety parameter available in electronic form from the safety parameter determining processor.
A medical imaging apparatus comprising:
- a medical data acquisition scanner having a patient-positioning device;
- a safety parameter determining processor;
- and
- a position data acquisition detector that is configured to acquire position data of the patient while the patient is situated on said patient-positioning;
- device, and to transmit the acquired position data to said safety parameter determining processor, wherein
- the safety parameter determining processor is configured to:
- evaluate the acquired position data to obtain position information of the patient;
- generate a patient model based on said position information of the patient, the patient model being an Active Shape Model;
- and
- determine a patient-specific safety parameter using the patient model, and to make the patient-specific safety parameter available in electronic form from the safety parameter determining processor.
A non-transitory, computer-readable data storage medium encoded with programming instructions, said programming instructions being loaded into a control computer of a medical imaging apparatus that comprises a position data acquisition detector and a safety parameter determining processor, said storage medium being encoded with programming instructions that cause said a position data acquisition detector and said safety parameter determining processor to:
- with said position data acquisition detector, acquire position data of the patient while the patient is situated on a patient-positioning device of the medical imaging apparatus;
- transmit the acquired position data to the safety parameter determining processor;
- in said safety parameter determining processor, evaluate the acquired position data to obtain position information of the patient;
- in said safety parameter determining processor, generate a patient model based on said position information of the patient, the patient model being an Active Shape Model;
- and
- in said safety parameter determining processor, determine a patient-specific safety parameter using the patient model, and make the patient-specific safety parameter available in electronic form from the safety parameter determining processor.
