Definitions
- the invention relates to a method for spectral testing of system components of a modular medical imaging system according to the preamble of claim 1.
- Modular medical imaging systems are already known, which include system components such as lighting, endoscope optics and a camera or several of these. Depending on the intended mode of operation, these can be combined with one another to form white-light imaging or fluorescence imaging. However, care must be taken to ensure that the system components set up for a particular function are used in order to correctly assemble the imaging system. If, for example, endoscope optics, which have an integrated fluorescence filter, are used as a system component for an unintended function such as white-light imaging, this leads to a distorted display. The use of lighting designed for the functionality is also important.
- a white light source is used for illumination in fluorescence imaging
- the fluorescence signal that is actually to be detected can be superimposed, as a result of which this background signal generated by the white light can be suppressed.
- the object of the invention consists in particular in providing a generic device with improved properties with regard to security.
- the object is achieved according to the invention by the features of patent claim 1, while advantageous configurations and developments of the invention can be found in the dependent claims.
- the invention is based on a method for the spectral examination of system components, namely at least one optical component and at least one lighting component, which are set up in a configuration provided for a function for assembling a modular medical imaging system.
- At least one test spectrum of a specified test object is recorded in at least one measurement step using the system components that are coupled to one another and a spectrometer, and that the recorded test spectrum is compared with at least one comparison spectrum that is characteristic of an intended mode of operation of the imaging device in at least one comparison step, and in a If the test spectrum matches the comparison spectrum, the imaging system is released for further use or if the test spectrum deviates from the comparison spectrum, a user is informed before subsequent use of the imaging system or the imaging system is blocked for subsequent use.
- the method is in particular a test and/or calibration method which is carried out prior to an examination of a patient using the medical imaging system. In particular, the method is not carried out on a patient.
- a “modular medical imaging system” is to be understood in particular as a system that is composed in a modular manner of various interchangeable medical system components that are set up for medical imaging. “Established” is to be understood to mean, in particular, specially programmed, designed, provided and/or equipped. The fact that an object is set up for a specific function is to be understood in particular to mean that the object fulfills and/or executes this specific function in at least one application and/or operating state.
- the imaging system is in particular an endoscopic, exoscopic and/or microscopic imaging system.
- the optical component is in particular an optical system, in particular such as an objective, an eyepiece, a relay optical system, a filter optical system of an endoscope, microscope and/or an exoscope, in particular with a fixed focal length and/or optical or digital zoom.
- the lighting component comprises in particular at least one light source and preferably a light guide which is set up to forward light from the light source.
- the light guide can be permanently connected to the light source.
- the light guide can be detachably coupled to the light source.
- the illumination can also already be integrated distally in the endoscope.
- the functions of such an imaging system can be understood to mean white light imaging, multispectral (MSI) and/or hyperspectral imaging (HSI), fluorescence imaging, preferably for photodynamic diagnostics (PDD), or the like.
- a “configuration of the system components” is to be understood in particular as a combination and/or an order in which these system components are arranged.
- the system components can differ from one another for different fluorescence imaging when using different fluorescent dyes or in the case of autofluorescence or can be matched to a specific wavelength range of a respective fluorescence.
- a light source of an illumination component can be matched to the absorption spectrum of a fluorescent dye.
- the optical components could be matched to the emission spectrum of a fluorescent dye.
- the system components are coupled to the spectrometer and/or to one another in the measuring step.
- the system components are connected upstream of the spectrometer luminous flux, so that a deviation of a test spectrum recorded by the spectrometer is influenced by the composition of the system components.
- a test object is preferably observed to record the test spectrum.
- the test object is in particular an object which consists at least for the most part of a homogeneous material composition and thus has advantageously macroscopically homogeneous spectral properties, such as a sheet of paper, a metal plate or the like.
- the imaging system includes at least one output device, which is used to inform a user of an incorrect configuration of the system components.
- the output unit may include an optical output element, such as a signal lamp, a screen or the like.
- the output unit could also have an acoustic output element, such as a loudspeaker. Haptic output elements would also be conceivable.

- Operational reliability can advantageously be further improved since it can be ensured on the basis of a test measurement whether the system components provided for a function are combined with one another.
- At least one intended configuration of the system components is set up for white-light imaging, multispectral and/or hyperspectral imaging.
- the imaging system thus has an advantageous mode of operation, by means of which a wide range of medical analyzes can be carried out, such as the detection of tissue types and/or tissue properties, such as water content, fat content, oxygenation, deoxygenation or the like.
- At least one configuration provided for the system components is set up for fluorescence imaging, this being in particular a further configuration provided which differs from the previous configuration.
- the imaging system thus has an advantageous mode of operation, by means of which a wide range of medical analyzes can be carried out, such as perfusion analysis, tumor detection, or the like.
- the various configurations provided differ in particular in terms of the use and/or arrangement of the system components.
- Fluorescence imaging is, in particular, fluorescence from a fluorescent dye delivered to the tissue, such as indocyanine green, fluorescein, 5-aminolevulinic acid (5-ALA), autofluorescence, or the like.
- the imaging system has a multispectral and/or hyperspectral camera which is set up to record at least one multispectral and/or hyperspectral image and which has the spectrometer. Additional components can advantageously be dispensed with, since the spectrometer is already part of the multispectral and/or hyperspectral camera.
- test spectrum is taken from the multispectral and/or hyperspectral test image.
- a particularly fast test step can advantageously be carried out, since the test spectrum can be recorded using only a single pixel, which is recorded with the multispectral and/or hyperspectral camera.
- averaging can be carried out over a number of pixels, rows, columns and/or an entire test image recorded with the multispectral and/or hyperspectral camera in order to determine the test spectrum .
