Method for determining of mass of patient through patient table and device having patient table

Abstract

A force sensor (10a) is attached to table leg (6) of patient table (4) supported with patient (2). Two positions of the tabletop relative to table leg are determined. The force values are determined using force sensor based table top and patient masses. The balance position (XA) of table top is determined based on force values, in which total center of gravity (22) of table top and patient are in predetermined spatial relationship to force sensor. A balance-force value (KA) for balance position is determined due to tabletop mass and patient mass at location of force sensor. An independent claim is included for a device for determining of mass of patient.

Description

technical field [0001] The invention relates to a method for automatically determining the patient mass of a patient placed on a patient table and to a device for carrying out the method. Background technique [0002] In some areas of medical imaging technology, patient quality is an important factor. In x-ray-based methods, the radiation dose or the contrast agent dose to be used, for example, generally depends on the patient mass. In this case, knowledge of the patient quality as accurately as possible enables a precise adjustment of the radiation dose or contrast agent dose to the minimum required and thus has very little impact on the patient with sufficient image quality. [0003] Normally, the patient's mass is determined by the examiner at the time of prior admission of the imaging study patient by asking about the patient's mass or by weighing the patient with the aid of a weighing scale. Patient quality is then typically maintained in an electronic patient file in...

AI Technical Summary

Problems solved by technology

[0004] However, sometimes it is not possible to question or weigh the patient, for example because the patient is unable to talk or stand in an acutely ill situation

In these cases, the best guess is to make a guess about the patient's weight, which can lead to an unnecessarily high burden on the patient or poor image quality
