CT Technician Job Description, KRAs and Skills

A CT Technician runs the CT scanner for emergency, inpatient and outpatient scans. They check the request and patient history, prepare and position the patient, choose the protocol and dose, handle contrast with the doctor or nurse, and reconstruct images for the radiologist. Stroke and trauma scans arrive at any hour, so the technician has to work fast without skipping a single safety check.

KRAs and KPIs for a CT Technician

Key result areas for the appraisal form, each with a KPI you can measure every month or quarter.

Key result area	How to measure it
Emergency scan time	Stroke CT started within 15 minutes of the patient reaching the CT room in 90 percent of cases
Repeat scans	Scans repeated because of technician error below 1 percent of studies
Dose control	Doses within department reference levels for 95 percent of routine protocols
Contrast safety	Creatinine and allergy check documented before every contrast scan
Study completeness	All images and reconstructions on PACS before the patient leaves the department
Daily QA	Calibration and phantom checks logged on every working day

Interview questions for a CT Technician

How would you time contrast for a CT pulmonary angiogram?
A patient's creatinine is 2.1 and the doctor wants a contrast CT. What do you do?
How do you reduce dose for a paediatric abdomen CT?
During injection the patient complains of pain at the IV site. What are your next steps?
What is the difference between MPR and MIP images?
An unconscious trauma patient arrives in a cervical collar. How do you position for head and spine CT?

Managing a CT Technician in ZeniaHR

AttendanceCT runs 24 hours in most hospitals, so technicians rotate across morning, evening and night duty with staggered weekly offs. Build the cycle once as a rotation template and assign it across the team, and let biometric punches at the imaging block confirm each shift.LeaveAt night one CT technician often runs the scanner alone, so any leave request covering a night week needs a named reliever. Shift swaps between CT-trained colleagues keep cover intact without HR editing the roster by hand.Performance and KRAsSet weighted KPI goals for emergency scan time, repeat rate, dose and contrast safety in an annual cycle, with the chief radiographer looking at register data every month. New CT technicians also go through a probation review rated 1 to 5.

Frequently asked questions

What does a CT technician do?

A CT technician prepares and positions patients, selects scan protocols and dose settings, handles contrast injections with the doctor or nurse, performs routine, angiography and emergency scans, reconstructs images for the radiologist and keeps daily quality checks and registers.

What qualification is needed to become a CT technician?

Most hospitals ask for a BSc in Radiology and Imaging Technology or a radiography diploma such as DMRIT, plus supervised training on CT. Freshers with a CT internship are hired for day shifts first, and move to independent night duty after they are signed off.

Is CT scan work risky for technicians?

CT uses X-rays, so there is occupational exposure, but technicians work from a shielded console room and wear TLD badges that record dose every quarter. With shielding, distance and time rules, doses stay low. The larger daily risks are lifting patients and handling contrast reactions.
