Abstract
There are provided an endoscopic diagnosis apparatus, lesion portion size detection method, and a non-transitory computer-readable recording medium that enable easy detection of the size of a lesion portion using an endoscope. This object is achieved by capturing an endoscopic image by emitting light having a regular repetitive pattern onto a subject, detecting, from the endoscopic image, a region in which a repetitive pattern is different from the repetitive pattern of the emitted light, and detecting at least one of a length and area of a lesion portion by using a number of repetitive patterns in the region in which the repetitive pattern is different and a size of a unit of repetition in the repetitive pattern.
Claims20
An endoscopic diagnosis apparatus comprising:
- an endoscope having a forceps outlet;
- light emitting unit for emitting light having a regular repetitive pattern, the light emitting unit being able to be protruded from the forceps outlet;
- and
- image analyzing unit for detecting, from an image for measurement which is an image captured by the endoscope in a state where light is emitted by the light emitting unit, a region in which a repetitive pattern is different from the repetitive pattern of the light emitted by the light emitting unit, and calculating at least one of a length and area of a lesion portion by using a number of repetitive patterns in the region in which the repetitive pattern is different and a size of a unit of repetition in the repetitive pattern.
A lesion portion size measurement method comprising:
- imaging a subject by emitting, with light emitting unit for emitting light having a regular repetitive pattern, the light having the repetitive pattern onto the subject by using an endoscope having a forceps outlet, the light emitting unit being protruded from the forceps outlet;
- detecting, in an image obtained by imaging the subject, a region in which a repetitive pattern is different from the repetitive pattern of the light emitted onto the subject;
- and
- calculating at least one of a length and area of a lesion portion by using a number of repetitive patterns in the region in which the repetitive pattern is different and a size of a unit of repetition in the repetitive pattern.
A non-transitory computer-readable recording medium on which a program is recorded, the program causing a computer to execute:
- a step of detecting, from an image obtained by imaging a subject by emitting a regular repetitive pattern, a region in which a repetitive pattern is different from the repetitive pattern of the emitted light;
- a step of counting a number of repetitive patterns in the region in which the repetitive pattern is different;
- and
- a step of calculating at least one of a length and area of a lesion portion by using the number of repetitive patterns in the region in which the repetitive pattern is different and a size of a unit of repetition in the repetitive pattern.
