MOKHOA OA HO KHETHA TRANSDUCER E NEPILENG BAKENG SA ULTRASOUND SCANNER?

Katleho easesebelisoa sa ho lekolahaholo-holo ho itšetlehile ka li-sensor tsa ultrasound tse kentsoeng ho eona.Palo ea bona sesebelisoa se le seng sa ho skena e ka fihla ho likotoana tse 30.Li-sensor ke eng, ke tsa eng le hore na u ka li khetha joang ka nepo - a re hlahlobeng ka hloko.

MEFUTA EA ULTRASONIC SENSOR:

• li-linear probes li sebelisoa bakeng sa tlhahlobo ea tlhahlobo ea meaho le litho tse sa tebang.Nako eo ba sebetsang ka eona ke 7.5 MHz;
• li-convex probes li sebelisoa ho hlahloba lisele le litho tse tebileng.Nako eo li-sensor tse joalo li sebetsang ka eona ke ka hare ho 2.5-5 MHz;
• li-sensor tsa microconvex - boholo ba ts'ebeliso ea tsona le khafetsa eo li sebetsang ho eona li tšoana le tsa mefuta e 'meli ea pele;
• intracavitary sensors - e sebelisetsoang lithuto tsa transvaginal le tse ling tsa intracavitary.Maqhubu a bona a ho hlahloba ke 5 MHz, ka linako tse ling a phahame;
• li-sensor tsa biplane li sebelisoa haholo-holo bakeng sa tlhahlobo ea transvaginal;
• li-sensor tsa intraoperative (convex, neurosurgical le laparoscopic) li sebelisoa nakong ea opereishene;
• li-sensor tse hlaselang - tse sebelisetsoang ho hlahloba methapo ea mali;
• li-ophthalmic sensors (convex kapa sectoral) - tse sebelisoang thutong ea leihlo la mahlo.Li sebetsa ka lebelo la 10 MHz kapa ho feta.

MOLAO-MOTHEO OA HO KHETHA LI-SENSOR BAKENG SA ULTRASOUND SCANNER

Ho na le mefuta e mengata e fapanengli-sensor tsa ultrasonic.Li khethoa ho latela kopo.Ho boetse ho eloa hloko lilemo tsa moqoqo.Ka mohlala, li-sensor tsa 3.5 MHz li loketse batho ba baholo, 'me bakeng sa bakuli ba banyenyane, li-sensor tsa mofuta o tšoanang li sebelisoa, empa ka lebelo le phahameng la ho sebetsa - ho tloha ho 5 MHz.Bakeng sa tlhahlobo e qaqileng ea li-pathologies tsa boko ba masea a sa tsoa tsoaloa, ho sebelisoa li-sensor tsa likarolo tse sebetsang ka lebelo la 5 MHz, kapa li-microconvex tse phahameng haholo.

Ho ithuta litho tsa ka hare tse tebileng, ho sebelisoa li-sensor tsa ultrasound, tse sebetsang ka makhetlo a 2.5 MHz, le bakeng sa mehaho e sa tebang, maqhubu a lokela ho ba bonyane 7.5 MHz.

Litlhahlobo tsa pelo li etsoa ho sebelisoa li-sensor tsa ultrasonic tse nang le antenna e tsamaeang ka mekhahlelo 'me li sebetsa ka lebelo le fihlang ho 5 MHz.Ho hlahloba pelo, ho sebelisoa li-sensor tse kenngoang ka 'metso.

Boithuto ba boko le litlhahlobo tsa transcranial li etsoa ho sebelisoa li-sensor, tseo hangata li sebetsang ke 2 MHz.Li-sensor tsa Ultrasound li sebelisoa ho hlahloba libe tsa maxillary , ka maqhubu a phahameng - ho fihlela ho 3 MHz.
