Abstract

A method for examining a patient in a medical imaging device is provided. The method includes measuring a pressure inside the body of the patient over a period of time during the examination, recording measurement data originating in the patient while the examination is in progress, reconstructing the medical image from the recorded measurement data, wherein the recording of the measurement data is controlled by the measured pressure and/or wherein the measured pressure is taken into account while the medical image is being reconstructed from the recorded measurement data.

Claims

1. A method for producing a medical image of a patient, the method comprising:

measuring a pressure inside a body of the patient over a period of time during a medical examination,

recording image measurement data originating in the patient during the examination, and

reconstructing a medical image from the recorded measurement data,

wherein recording of the measurement data is controlled with the measured pressure, reconstructing the medical image from the recorded measurement data is carried out using the measured pressure, or a combination thereof.

2. The method as claimed in claim 1, further comprising:

evaluating the measured pressure during the examination, and interrupting the recording of measurement data when the measured pressure is outside a tolerance range or exceeds a threshold value.

3. The method as claimed in claim 1, further comprising:

discarding a part of the recorded measurement data during the reconstruction of the medical image when the measured pressure is outside a tolerance range or exceeds a threshold value during the recording of said part of the measurement data.

4. The method as claimed in claim 1, wherein the medical imaging device is a nuclear medical imaging device, a magnetic resonance imaging device, or a computer tomography imaging device.

5. The method as claimed in claim 1, wherein the measured pressure inside the body is a gas pressure.

6. The method as claimed in claim 1, wherein measuring the pressure includes measuring a pressure in a hollow organ of the body.

7. The method as claimed in claim 6, wherein the pressure in the intestine is measured.

8. An imaging device for examining a patient, comprising:

a sensor that is operable to measure a pressure inside the body of a patient while measurement data is being recorded,

a recording unit that is operable to record the measurement data originating in the patient,

a processing unit that is operable to generate a medical image based on the recorded measurement data,

wherein the recording unit controls the recording of the measurement data based on the measured pressure, the processing unit reconstructs the medical image from the recorded measurement data using the measured pressure, or a combination thereof.

9. The imaging device as claimed in claim 8, wherein the sensor is operable to measure pressure in a hollow organ of the body.

10. The imaging device as claimed in claim 9, wherein the sensor is operable to measure pressure in the intestine.

11. The imaging device as claimed in claim 8, wherein the sensor is disposed on a valve mechanism for releasing an excess pressure.

12. The imaging device as claimed in claim 8, wherein the sensor is disposed on an inflatable balloon.

13. The imaging device as claimed in claim 8, wherein the sensor is operable to be inserted into in the intestine rectally.

14. The imaging device as claimed in claim 8, wherein the sensor is operable to measure a gas pressure.
