Abstract

A system and method may generate a radiological request by which to conduct a radiological procedure that employs a series of procedural steps to acquire internal images of a patient. Each step may have a corresponding protocol item which affects image quality and the time required to complete the step. A database may be maintained that includes protocol items and patient characteristic data. A rule-based algorithm may accept patient characteristic data as input. Based upon one or more patient characteristics, an overall protocol by which to conduct the radiological procedure may be determined. The tailored protocol may include steps that are selected, omitted, and/or altered based upon a patient characteristic. The patient characteristics may be medical restrictions, such as age, pregnancy, allergies, artificial joints, or other limitations. As a result, the protocol items may be automatically selected based upon patient specific characteristics, and/or an anatomical structure to be examined.

Claims

1. A data processing system for planning radiological requests, the system comprising:

a memory configured to store patient data associated with a patient that is to undergo a current radiological procedure and a plurality of pre-determined protocol items related to acquiring images of one body area of the patient, each of the pre-determined protocol items being associated with the physical operation of a medical imaging device during a radiological procedure;

a processor configured to retrieve updated patient data from a remote medical facility and update the patient data stored in the memory to reflect the updated patient data retrieved from the remote medical facility, the updated patient data being acquired during a previous examination of the patient performed at the remote medical facility and containing a new patient restriction identified during the previous examination; and

the processor further configured to determine an optimized protocol by which to conduct the current radiological procedure by employing a rule-based algorithm acting upon the updated patient data, wherein the rule-based algorithm employed automatically determines the optimized protocol from among the plurality of pre-determined protocol items related to acquiring images of one body area of the patient as a function of (1) a body area of the patient to be examined during the current radiological procedure and (2) the new patient restriction contained within the updated patient data retrieved from the remote medical facility, and the processor facilitates the performance of the optimized protocol to acquire images of the body area of the patient to be examined such that the new patient restriction identified during the previous examination of the patient performed at the remote medical facility is automatically accounted for during the current radiological procedure.

2. The system of claim 1, wherein the processor is operable to control an imaging device to conduct the current radiological procedure in accordance with the optimized protocol.

3. The system of claim 2, wherein the optimized protocol results in an optimum image quality in the images acquired by the imaging device in view of (1) the body area to be examined and (2) the new patient restriction identified during the previous examination of the patient.

4. The system of claim 2, wherein the imaging device is a modality.

5. The system of claim 2, wherein the optimized protocol results in an optimum procedural time required to acquire images of the body area to be examined and account for the new patient restriction identified during the previous examination of the patient.

6. A data processing system for planning radiological requests, the system comprising:

a memory storing a plurality of pre-determined protocols associated with a specific type of radiological device operable to acquire images of a body area of a patient;

a processor configured to retrieve up-to-date patient characteristic information associated with the patient from a remote database, the up-to-date patient characteristic information being acquired during a previous medical examination of the patient performed at a remote medical facility; and

the processor further configured to employ a rule-based algorithm to select an optimized protocol by which to conduct a radiological procedure from among the plurality of pre-determined protocols associated with the specific type of radiological device,

wherein the up-to-date patient characteristic information includes a new patient restriction identified during the previous medical examination of the patient performed at the remote medical facility, and the rule-based algorithm selects the optimized protocol from among the plurality of pre-determined protocols associated with the specific type of radiological device as being a function of (1) the new patient restriction identified during the previous medical examination of the patient performed at the remote medical facility and (2) the body area of the patient to be examined, and

the optimized protocol selected by the rule-based algorithm from among the plurality of pre-determined protocols associated with the specific type of radiological device is used by the processor in acquiring images of body area of the patient to be examined such that the new patient restriction identified during the previous medical examination of the patient performed at the remote facility is accounted for in the acquiring of the images.

7. The system of claim 6, wherein the optimized protocol comprises a list of protocol items to be employed during the course of the radiological procedure.

8. A method of planning a radiological request, the method comprising:

pre-determining a plurality of potential procedural steps associated with an overall radiological procedure performed via an imaging device to acquire medical images of a patient;

storing the pre-determined plurality of potential procedural steps in a database;

retrieving a new patient restriction that impacts the overall radiological procedure performed via the imaging device from a remote medical facility via a processor, the new patient restriction being identified during a previous examination of the patient performed at the remote medical facility;

automatically tailoring the overall radiological procedure to account for the new patient restriction identified by configuring the processor to accept the new patient restriction identified during the previous examination of the patient performed at the remote medical facility as a first input parameter and a body area of the patient to be examined as a second input parameter, and then automatically select one or more procedural steps from among the pre-determined plurality of potential procedural steps associated with the overall radiological procedure, as a function of the first and second input parameters, to achieve an optimized protocol that is optimum for the new patient restriction identified and the body area of the patient to be examined; and

acquiring images of the body area of the patient using the optimized protocol.

9. The method of claim 8, wherein the optimized protocol comprises a list of protocol items to be employed during the overall radiological procedure.

10. A method of planning a radiological request, the method comprising:

retrieving updated patient information from a database, the updated patient information including a new patient restriction identified during a previous medical examination of a patient performed at a remote medical facility;

identifying a body area of the patient to be examined;

a rule-based algorithm automatically selecting, from a plurality of pre-determined protocol items associated with the body area, a protocol item to be employed during a radiological procedure via a processor as a function of the new patient restriction identified during the previous medical examination of the patient performed at the remote medical facility and the body area of the patient to be examined; and

acquiring images of the anatomical structure body area of the patient to be examined via an imaging device controlled by the processor in accordance with the protocol item automatically selected.

11. The method of claim 10, wherein the protocol item automatically selected comprises a set of physical parameters that control the acquisition of the image by the imaging device.
