Description

Optical coherence tomography apparatus having adjustment mechanism

Technical Field

The present invention generally relates to an optical coherence tomography apparatus having an adjustment mechanism.

Background

An Optical Coherence Tomography (OCT) apparatus is a high-precision imaging apparatus that non-invasively detects biological tissue and obtains a two-dimensional or three-dimensional structural image of the biological tissue. And are therefore commonly used for non-invasive imaging in biological systems, for example in ophthalmology for imaging the eye of a subject to be tested. Optical coherence tomography can accurately characterize the pathological features of the eye, and can provide objective basis for diagnosis and treatment of clinicians.

Currently, an optical coherence tomography imaging apparatus typically has several parts, a reference arm, a scanning arm, a light source, a spectrometer, and a photodetection system. However, most devices typically require the scanning arm to be fixed to a table for use, and therefore require the object to be measured to maintain the head upright for use with the device. Therefore, such an optical coherence tomography apparatus may not be effective for eye examination of subjects whose heads are inconvenient to keep upright, such as infants, premature babies, anesthetized patients, and bed-ridden patients. In recent years, therefore, portable optical coherence tomography apparatuses have appeared, mainly by arranging the scanning arm to be hand-holdable to achieve effective eye detection of premature babies, infants and bedridden patients.

However, when an operator performs eye detection on an object to be measured using a handheld scanning arm of a portable optical coherence tomography apparatus, it is difficult to obtain a clear image by manually adjusting the position of the scanning arm. In addition, shaking of the operator's arm may have an effect on the imaging quality.

Embodiments of the present invention relate to an optical coherence tomography apparatus having a probe. For convenience of description, the optical coherence tomography apparatus may be simply referred to herein as an "OCT apparatus".

In some examples, the OCT apparatus 1 according to the present invention may be used to detect an eye of the object 2 to be measured. In some examples, the optical coherence tomography device 1 may operate based on spectral domain optical coherence tomography principles, such as an SD-OCT device.

Fig. 1 is a view showing an application scenario of an optical coherence tomography apparatus 1 according to an embodiment of the present invention. Fig. 2 is a schematic diagram showing an optical coherence tomographic imaging apparatus 1 according to an embodiment of the present invention. Fig. 3 is a block diagram showing the optical coherence tomographic imaging apparatus 1 according to the embodiment of the present invention.

In some examples, OCT device 1 may include a host 10, an adjustment mechanism 20, and a probe 30.

In some examples, the probe 30 may include a hand-held housing 31 and a sampling module 32. In some examples, sampling module 32 may be used to sample the eyes of object 2. In some examples, the sampling module 32 is disposed inside the hand held housing 31.

In some examples, host 10 may include a light source 11, a reference arm 12, a processing device 13, and a display device 14.

In some examples, the probe 30 is connected to the host 10 by an optical fiber. In this case, the light emitted from the light source 11 may be transmitted to the probe 30 via an optical fiber. Therefore, the probe 30 can conveniently transmit signals with the host computer 10 during moving.

In some examples, the light emitted from the light source 11 is split and a portion of the split light is transmitted to the reference arm 12 to form the reference signal. A part of the signal is transmitted to the probe 30 via the optical fiber and reflected by the object 2 to be measured to form a measurement signal. The processing means 13 derive a target image on the basis of the measurement signal and the reference signal. In some examples, display device 14 may display the target image.

Fig. 4 is a partial schematic view showing the adjustment mechanism 20 of the optical coherence tomographic imaging apparatus 1 according to the embodiment of the present invention.

In some examples, the adjustment mechanism 20 may include a fixing portion 21, an adjustment lever 22, and a support portion 23. In some examples, adjustment mechanism 20 may be secured to host 10 by a securing portion 21.

In some examples, the support 23 may be provided with a focusing part 231. That is, in some examples, the adjustment mechanism 20 may include a fixing portion 21, an adjustment lever 22, a support portion 23, and a focusing portion 231.

In some examples, the probe 30 may be placed on the support 23. In some examples, the focusing part 231 can control the probe 30 placed on the support 23 to move in a preset direction. Specifically, when the probe 30 placed on the support 23 is used to perform image acquisition on the eye of the object 2, the focusing section 231 can control the probe 30 to move closer to or away from the eye of the object 2.

In some examples, one end of the adjustment lever 22 is movably connected with the fixing portion 21, and the other end is provided with a support portion 23. In some examples, the adjustment lever 22 may be configured to move the support 23. In this case, the support portion 23 is movable relative to the fixing portion 21, and the relative position of the probe 30 positioned on the support portion 23 and the eye of the object 2 is further adjusted. Thereby, it is possible to provide the optical coherence tomographic imaging apparatus 1 having the portable probe 30 which is easy to operate and can stably image.

In the present invention, the adjustment mechanism 20 can support the probe 30, reducing the possibility of the probe 30 shaking during image acquisition.

In some examples, the adjustment lever 22 may include a first movable bar 221 and a second movable bar 222. In some examples, the first movable bar 221 may be movably connected with the fixed part 21. In some examples, the first movable bar 221 may be disposed to rotate with respect to the fixed part 21. In some examples, the second movable bar 222 may be movably connected with the first movable bar 221. In some examples, the second movable bar 222 may be disposed to rotate relative to the first movable bar 221.

In some examples, the first movable bar 221 may rotate in a horizontal plane. In some examples, the second movable bar 222 may rotate in a vertical plane.

In some examples, the adjustment lever 22 may also include a third movable lever 226. In some examples, the third movable bar 226 may be movably connected with the second movable bar 222. In some examples, the third movable bar 226 may rotate relative to the second movable bar 222. In some examples, the bearing portion 23 is provided at one end of the third movable bar 226. Thus, the support portion 23 can be provided on the adjustment lever 22 and can be interlocked with the first, second, and third movable levers 221, 222, and 226.

In some examples, the adjustment lever 22 is provided with a plurality of locking portions (described later). This can reduce the possibility of the adjustment mechanism 20 shaking during image acquisition.

In some examples, the adjustment lever 22 may be provided with a first locking portion 223 thereon. In some examples, the first locking portion 223 may be disposed on the first movable bar 221. In this case, when the first locking portion 223 is locked, the second movable lever 222 may be fixed to the first movable lever 221.

In some examples, the adjustment lever 22 may also include a second locking portion 225. In some examples, the second detent 225 can secure the third movable bar 226 to the second movable bar 222.

In some examples, the adjuster rod 22 may also include a third latch portion 224. In some examples, the third lockout portion 224 may prevent the second movable bar 222 from automatically descending due to gravity during image acquisition.

Fig. 5 is a schematic diagram showing that the probe 30 of the light coherence tomographic imaging apparatus 1 according to the embodiment of the present invention is attached to the adjustment mechanism 20. Fig. 6 is a block diagram showing the probe 30 of the optical coherence tomography apparatus 1 according to the embodiment of the present invention.

In some examples, the bearing 23 may be provided on the adjustment lever 22. In some examples, the support portion 23 is provided on the third movable bar 226 so as to move in a length direction of the third movable bar 226. In some examples, a drive 228 may be provided on the adjustment lever 22. In some examples, the driving portion 228 may drive the supporting portion 23 to move along the length direction of the third movable bar 226. In this case, the position of the light emitted from the light source 11 that is irradiated to the eye of the object 2 through the probe 30 can be changed, and when the light that has passed through the probe 30 is irradiated to the position of the pupil, the display position of the target image on the display device 14 is relatively suitable for the observation habit of the operator.

In some examples, the support portion 23 may include an angle adjustment portion 232. That is, the adjustment mechanism 20 may include an angle adjustment part 232 provided on the support part 23. In some examples, the angle adjuster 232 may be used to adjust an imaging angle. Therefore, the imaging angle of the image collected by the display device 14 can be adjusted, and the operator can observe the image more conveniently. That is, when the probe 30 placed on the support 23 is substantially aligned with the eye of the object 2, the imaging angle of the target can be made to be the desired angle of the operator by turning the angle adjustment part 232.

In some examples, the angle adjustment part 232 may be adjusted to rotate in a horizontal plane when the object 2 to be measured is in a lying state. When the object 2 to be measured is in an upright state, the angle adjusting unit 232 may be adjusted to rotate in a vertical plane.

In some examples, a restriction 233 may be provided on the support 23. In some examples, the restricting part 233 may be used to restrict the angle adjusting part 232 from rotating. In some examples, the locking portion 229 may be a locking screw or a locking knob. This reduces the possibility of the angle adjusting unit 232 rotating during image acquisition, and further reduces the possibility of the support unit 23 or the probe 30 shaking during imaging.

In some examples, the focus 231 includes a focus knob 2311 and an actuator assembly 2312. In some examples, the actuator 2312 may move the probe 30 relative to the eye of the object 2 under the action of the focus knob 2311.

In some examples, the light source 11 may be a laser light source. In some examples, the light source 11 may be an SLD (super luminescent diode) light source. In this case, due to the wide spectral width and low coherence of the SLD light source, the light emitted from the SLD light source propagates through the optical fiber, which is advantageous for obtaining an accurate target image. In some examples, the central wavelength of the light signal emitted from the light source 11 may be 830-850nm, and the bandwidth may be 100-200 nm.

In some examples, light from light source 11 may pass through fiber coupler 15 and enter reference arm 12 and sampling module 32, respectively. In some examples, the coupling ratio of the fiber coupler 15 may be any ratio. For example, the coupling ratio may be 50: 50, 20: 80, 30: 70. in some examples, the ratio of light emitted by the light source 11 entering the reference may be controlled to be not less than the ratio of light entering the sampling module 32 by changing the coupling ratio.

In some examples, the sampling module 32 may include a first collimating mirror 321, a first lens 322, a second lens 324, and a first galvanometer mirror 323. In some examples, the light emitted from the light source 11 may be focused on the object 2 through the first collimating lens 321, the first lens 322, the first scanning mirror 323, and the second lens 324, and form a measurement signal after being reflected by the object 2.

In some examples, the probe 30 may also include a display module 33. In some examples, the display module 33 may be provided to the hand-held housing 31. In some examples, the display module 33 may be used to monitor eye real-time position information of the object 2 to be measured. In this case, the operator can simultaneously observe the relative positions of the probe 30 and the eyes of the object 2 while the probe 30 is moved.

In some examples, display module 33 may include a camera 331 and a display 332. In some examples, the camera 331 may be a pupil camera. In some examples, the pupil camera may be used to monitor the eye real-time position information of the object 2 to be measured in real time. The display 332 may feed back the real-time eye position information of the object 2 to be measured to the operator in real time.

In some examples, the display 332 may be disposed on the handheld housing 31. In this case, the operator can simultaneously observe the relative positions of the probe 30 and the eyes of the object 2 while the probe 30 is moved. Thus, the display 332 integrated on the hand-held housing 31 can feed back the position information of the pupil in real time to assist the operator in judging the scanning position. In some examples, the eye real-time position information of the object 2 to be measured detected by the pupil camera may also be transmitted to the processing device 13 and displayed in the display device 14.

In some examples, the probe 30 may also include a fixation module 34. In some examples, the fixation module 34 may include an auxiliary light source 341. In some examples, the auxiliary light source 341 may emit fixation light into the eye of the object 2 to be measured. In some examples, the gaze light may have a particular shape. In this case, the vision fixation module 34 may guide the line of sight of the object 2, so as to reduce the possibility of head or eye movement of the object 2 during detection. In addition, the vision fixation module 34 guides the object 2 to be detected to move consciously, so that multi-angle imaging can be conveniently carried out on the eyes.

Fig. 9 is a schematic view showing a visual effect of the auxiliary light source 341 according to the embodiment of the present invention. In some examples, the auxiliary light source 341 may be an LCD display screen. In which case it can be controlled by the processing means 13 to display different fixation patterns. In some examples, the visual effect of the fixation pattern may be substantially as shown in fig. 9. In some examples, the fixed view pattern may be in the form of a cartoon character. In this case, the attention of the infant can be attracted.

In some examples, auxiliary element 36 may include an ophthalmoscope 363. In some examples, the ophthalmoscope 363 is detachably attached to the probe 30. Specifically, in some examples, the measurement signal may carry information of the posterior segment of the eye (e.g., the retina) when the ophthalmoscope 363 is attached to the probe 30. In some examples, the measurement signal may carry information of the anterior segment of the eye (e.g., the cornea) when the ophthalmoscope 363 is detached from the probe 30.

In some examples, the first lens 322 may be a tunable lens. In particular, the adjustable focus lens may be a liquid lens. In some examples, the focus range of the focus adjustable lens may be 50 to 120 mm. In some examples, the first lens 322 may be controlled by the processing device 13, and controlling the first lens 322 by the processing device 13 may perform a focusing process on the incident light, thereby enabling auto-focusing for different eye lengths. In addition, the focus can be quickly focused in accordance with the focus adjusting section 231.

In some examples, the second lens 324 may be a focus adjustable lens. In some examples, the second lens 324 may be manually adjusted. In this case, the second lens 324 can be adjusted according to the diopter of the eye of the object 2 to be measured, so that the image can be made sharp.

Fig. 10 is a schematic diagram showing the probe 30 of the optical coherence tomographic imaging apparatus 1 according to the embodiment of the present invention.

In some examples, the handheld housing 31 may include a grip 311 and a scanning head 312. In some examples, the grip 311 and the scanning head 312 may generally form a predetermined angle therebetween.

In some examples, the predetermined angle may be configured such that the scanning head 312 is substantially directed toward the object 2 to be measured when the grip portion 311 is in a posture of being gripped or clamped. In some examples, the predetermined angle may be substantially between 90 ° and 180 °.

Fig. 11 is an operation principle diagram showing the reference arm 12 of the optical coherence tomographic imaging apparatus 1 according to the embodiment of the present invention.

In some examples, reference arm 12 may include a second collimating mirror 121, a second scanning galvanometer 122, a first focusing lens 123, and a first mirror 124. In this case, the light entering the reference arm 12 may sequentially pass through the second collimating mirror 121, the second scanning galvanometer 122, and the first focusing lens 123 to reach the first reflecting mirror 124, and then sequentially pass through the first focusing lens 123, the second scanning galvanometer 122, and the second collimating mirror 121 after being reflected by the first reflecting mirror 124, so as to form the reference signal. In this case, the reference signal may interfere with the measurement signal carrying information of the anterior segment of the eye.

In some examples, the reference arm 12 may further include a dispersion compensation device 125, a second collimating mirror 121, a second scanning galvanometer 122, a second focusing lens 126, and a second mirror 127. In this case, the light entering the reference arm 12 may sequentially pass through the second collimating mirror 121, the second scanning galvanometer 122, the dispersion compensating device 125, and the second focusing lens 126 to the second reflecting mirror 127 and be reflected by the second reflecting mirror 127, and then sequentially pass through the second focusing lens 126, the dispersion compensating device 125, the second scanning galvanometer 122, and the second collimating mirror 121 to form the reference signal. In this case, the reference signal may interfere with the measurement signal carrying information of the posterior segment of the eye.

In some examples, when the second scanning galvanometer 122 is at a first angle, light entering the reference arm 12 may form a reference signal that may interfere with a measurement signal carrying anterior eye information. In some examples, when the second scanning galvanometer 122 is at a second angle, light entering the reference arm 12 may form a reference signal that may interfere with a measurement signal carrying posterior segment information of the eye.

In some examples, the scanning frequency of the second scanning galvanometer 122 can be 100-800 KHz, and the response speed can be 50-800 us. In some examples, the scanning frequency of the second scanning galvanometer 122 may preferably be 200KHz, and the response speed may preferably be 400 us.

In some examples, light entering reference arm 12 may strike second mirror 127 perpendicular to it through second focusing lens 126. In some examples, the second mirror 127 is movable. In some examples, light entering the reference arm 12 may strike the first mirror 124 perpendicularly after passing through the first focusing lens 123. In some examples, the first mirror 124 is movable. In this case, image acquisition may be performed with different ocular parameters (e.g., ocular axis length).

In some examples, the reference arm 12 may also include a second polarization controller 128. Therefore, the polarization state of the light path can be better controlled, the consistency of the reference signal is ensured, and the imaging quality is further improved.

In some examples, the reference arm 12 may also include a filter 129.
