Problems solved by technology

These methods in the prior art, due to inaccurate weight information, also have data input errors caused by operator negligence, which lead to potential safety problems due to calculation deviations during safety monitoring, or lead to restrictions on applied parameters
[0003] In order to overcome the defects in the prior art that the weight information is inaccurate due to the need for the patient to self-report the weight, the operator to estimate the weight, and the automatic entry of the weighing, and the information input is prone to errors, etc., it is necessary to propose a new weight measurement method and its measuring equipment

Embodiment 1

[0036] In this embodiment, the scissor lifting device 1 is adopted, and the driving device 2 is a motor driving device. The lifting device 1 is driven by the driving device 2 , the driving device 2 is connected with the measuring device 3 , and the data processing unit 4 receives the measurement data of the measuring device 3 .

[0037] After the patient (i.e. the target to be measured) rests quietly on the lifting device 1 according to the requirements, the driving device 2 drives the lifting device 1 to carry out the lifting operation, and the lifting device 1 is lifted to the highest position. The measuring device 3 measures the power information P of the driving device 2 in the driving process in real time support , P total , P friction , P tabletop . The data processing unit 4 acquires the power data measured by the measuring device 3 in real time, and calculates the patient's weight based on the power data.

[0038] Due to the power P required to lift the patient to...

Embodiment 2

[0050] In this embodiment, the lifting device 1 is still a scissor-type lifting device, and the driving device 2 adopts a hydraulic driving device. The driving device 2 drives the lifting device 1 to carry out the lifting operation, the measuring device 3 is connected with the driving device 2, and the data processing unit 4 is set in the host computer of the nuclear magnetic resonance system.

[0051] After the patient lies quietly on the lifting device 1 according to the requirements, the driving device 2 drives the lifting device 1 to carry out the lifting operation, and the lifting device 1 is lifted to the highest position. When the driving device 2 is driving the lifting device 1 , the measuring device 3 acquires the pressure of the liquid therein through the pressure sensor in the hydraulic driving device. There is a link between changes in pressure and body weight.

[0052] Data processing unit 4 obtains the patient's body weight according to the following formula III...

Abstract

The invention discloses a weight measurement method. The method is characterized in that a detected object is arranged on a lifting device; a driving device drives the lifting device, so that the detected object is allowed to go up and go down vertically; a measurement device measures power consumed by the driving device during driving the lifting device or pressure of the driving device, so that power data or pressure data is obtained; and the power data or the pressure data is received by a data processing unit, and the weight of the detected object is calculated based on the power data or the pressure data. According to the weight measurement method, in the process of enabling the detected object to go up and down, the weight of the detected object is calculated based on the power data or the pressure data, obtained through measurement, of the driving device, thereby realizing integration of scanning and weighting during nuclear magnetic resonance, simplifying weight measurement in the process of NMR imaging, and ensuring accuracy of weight obtaining and inputting. The invention also discloses a weight measurement device and a NMR (nuclear magnetic resonance) imaging system comprising the weight measurement device.

Description

technical field [0001] The invention belongs to a body weight measurement method, in particular to a body weight measurement method, body weight measurement equipment and a nuclear magnetic resonance imaging system in the process of nuclear magnetic resonance imaging. Background technique [0002] In the process of using the nuclear magnetic resonance imaging system to perform nuclear magnetic resonance imaging, it is necessary to know the patient's weight information, which is used for software safety monitoring, such as SAR monitoring. One of the usual methods is for the patient to report a weight value by himself, or to estimate a value by the operator based on the observed patient information, or to input it into the system by the operator through the software interface after weighing on the scale in the patient preparation room. These methods in the prior art, due to inaccurate weight information, also have data input errors caused by operator negligence, which lead to ...
