Technical Field

The invention relates to the field of head and neck tumors, in particular to a surgical data extraction system based on signal analysis.

Background

The head and neck tumor comprises three major parts of neck tumor, otorhinolaryngology tumor and oral cavity maxillofacial tumor. Neck tumors belong to common surgery in comprehensive hospitals, and are thyroid tumors in common; common tumors of the otolaryngology department include laryngeal carcinoma, paranasal sinus carcinoma and the like; oral and maxillofacial tumors are commonly found in various oral cancers, such as tongue cancer, gingival cancer, buccal cancer, etc. Therefore, the tumors of the head and neck, which have many primary sites and pathological types, are the top of the tumors of the whole body. Meanwhile, important organs of the head and the neck are concentrated, the anatomical relationship is complex, and the treatment methods are different.

For the diagnosis of advanced cervical metastatic cancer, the diagnosis depends on inquiring about the history of tumor at other parts, and can be made clearly by means of CT, MR, cervical fine needle aspiration biopsy and the like. Meanwhile, the relationship between the cervical metastatic cancer and the carotid artery can be observed by applying selective carotid angiography and B-ultrasound. For advanced cervical metastatic cancer, a comprehensive therapy method with surgery as the main therapy and radiotherapy and chemotherapy as the auxiliary therapy before and after surgery is adopted.

However, in the conventional treatment mechanism for head and neck tumors, it is impossible to determine whether or not an open cranium operation needs to be performed based on the size of an intracranial tumor and whether or not an open cranium operation needs to be performed based on the intracranial hemorrhage volume area, and the judgment of the treatment timing of the head and neck tumors is too dependent on manual experience.

Detailed Description

Embodiments of the surgical data extraction system based on signal analysis according to the present invention will be described in detail below with reference to the accompanying drawings.

According to the data provided by the international epidemiological research organization, the annual incidence rate of the head and neck tumors is 15.22/10 ten thousand in recent years, and accounts for 4.45 percent of the malignant tumors of the whole body. The onset of head and neck tumors was, according to site, laryngeal (32.1%), thyroid (19.6%), oral (16.1%), nasopharynx (14.9%), paranasal sinus (6.6%), salivary gland (4.2%), oral (3.3%), ocular (1.52%), hypopharynx (1.5%) in order. In gender, except thyroid tumor women (14.2%) were significantly more numerous than men (5.40%), the rest were men.

The incidence of head and neck tumors varies from place to place due to different living environments and different pathogenic factors. For example, nasopharyngeal carcinoma is more frequently encountered in two areas of China, while thyroid tumor is more frequently encountered in coastal and inland areas lacking iodine.

The intracranial tumor mechanism in the prior art cannot determine whether the craniotomy needs to be performed or not based on the size of the intracranial tumor and determine whether the craniotomy needs to be performed or not based on the intracranial hemorrhage volume area, so that the judgment of the treatment time of the head and neck tumor is too dependent on manual experience, on one hand, the reliability of diagnosis is not high, and on the other hand, a complex judgment procedure is needed.

In order to overcome the defects, the invention builds a surgical data extraction system based on signal analysis, and can effectively solve the corresponding technical problem.

In addition, CMOS (Complementary Metal-Oxide-Semiconductor), which is known as CMOS in the Chinese scientific name, is an important chip in a computer system and stores the most basic data for system booting. The CMOS manufacturing technology is not different from that of a common computer chip, and mainly utilizes a semiconductor made of two elements, namely silicon and germanium, so that N (band-electric) and P (band + electric) level semiconductors coexist on the CMOS, and the current generated by the two complementary effects can be recorded and interpreted into an image by a processing chip. CMOS has later been processed to also serve as an image sensor in digital photography.

For portable applications independent of the power grid, CMOS technology, which is known for its low power consumption characteristics, has a clear advantage: CMOS image sensors are designed for 5V and 3.3V supply voltages. The CCD chip requires a power supply voltage of about 12V, and therefore a voltage converter has to be employed, resulting in an increase in power consumption. Integrating control and system functions into a CMOS sensor would provide another benefit in terms of overall power consumption: he removes all external connection lines to other semiconductor elements. Drivers with their high power consumption have been abandoned today because the energy consumed to communicate inside the chip is much lower than with external implementations through a PCB or substrate.

CMOS sensors can also be subdivided into Passive Pixel sensors (Passive Pixel Sensor CMOS) and Active Pixel sensors (Active Pixel Sensor CMOS).

A Passive Pixel Sensor (PPS), also called Passive Pixel Sensor, is composed of a reverse biased photodiode and a switching transistor. The photodiode is essentially a PN junction composed of a P-type semiconductor and an N-type semiconductor, and it can be equivalently a reverse biased diode in parallel with a MOS capacitor. When the switch tube is opened, the photosensitive diode is communicated with a vertical Column line (Column bus). A Charge integrating amplifier read circuit (Charge integrating amplifier) at the end of the column line keeps the column line voltage constant, and when the signal Charge stored in the photodiode is read, the voltage is reset to the column line voltage level, and at the same time, the Charge proportional to the optical signal is converted into a Charge output by the Charge integrating amplifier.

An Active Pixel Sensor (APS) is also called an Active Pixel Sensor. Almost at the same time as the invention of the CMOS PPS pixel structure, it was quickly realized that the performance of the pixel could be improved by introducing buffers or amplifiers within the pixel, with its own amplifier within each pixel in the CMOS APS. The amplifying transistor integrated on the surface reduces the effective surface area of the pixel element, reduces the packaging density and enables 40% -50% of incident light to be reflected. Another problem with such sensors is how to achieve a better match between the multi-channel amplifiers of the sensor, which can be better achieved by reducing the residual level of fixed pattern noise. CMOS APS has less power consumption than CCD image sensors because each amplifier within the pixel is activated only during this readout.

It is to be understood that while the present invention has been described in conjunction with the preferred embodiments thereof, it is not intended to limit the invention to those embodiments. It will be apparent to those skilled in the art from this disclosure that many changes and modifications can be made, or equivalents modified, in the embodiments of the invention without departing from the scope of the invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention, unless the contents of the technical solution of the present invention are departed.
